You will find the glossary at the end of the Engineering Manual System Configuration.


Section 1 Overview

AC 900F ControllerThe PM 902F or PM 901F CPU module is the core component of an AC 900F controller. As there are only minor differences in appearance between both CPU module types, the drawings and photos of the PM 902F included in the present document also apply to the PM 901F.

The term “controller” used in this manual is equivalent to the term “process station” in Freelance Engineering or to the precise type designation “AC 900F”.

AC 900F_ Controller.png

Unless a description refers to special features and functions of a specific module type variant, the general type designations PM, CI, TA, TU etc. are used throughout this document.

Depending on the application and requirements, the controller can be complemented by additional modules. These modules are fieldbus communication interfaces and I/O modules.


AC 900F Controller Section 1 Overview

The AC 900F comprises the following components:

• PM CPU module with

– PM 902F: four Ethernet interfaces

– PM 901F: three Ethernet interfaces

– one diagnostic interface

– two serial interfaces

– one TD display unit (optional)

• up to ten S700 I/O modules with I/O terminal blocks

• max. two CI/CM fieldbus communication interfaces

The controller can be used in single or redundant configuration. It supports remote I/Os, transmitters, actuators, drives, and other devices using PROFIBUS and other fieldbus protocols. ABB offers a wide range of different devices and network components for applications in standard and hazardous areas.

In the present version, the AC 900F controller supports the following fieldbus technologies:

• PROFIBUS-DP V0/V1

• Modbus RTU (serial) and Modbus TCP

• Telecontrol protocol (serial) and Telecontrol TCP

• ABB CAN Bus protocol

Depending on type and number of process signals, input/output modules are used either as “direct” I/O or as remote I/O. For more detailed information on assembly and installation of I/O modules, please refer to Mounting and Installation Instructions, I/O Modules for AC 700F / AC 900F.

Similar to the AC 700F and AC 800F, the hardware configuration of the AC 900F is based on the hardware function block principle.

The AC 900F controller is designed for the combination with fieldbus-compliant components like remote I/O, field devices and network components. ABB offers equipment for applications in standard and hazardous areas.

Communication

System

TCP/IP, UDP/IP

The Control Net (Ethernet) connects the individual stations with each other. It transfers data between the controllers and between Freelance Operations, the gateways and Freelance Engineering. The AC 900F controller supports data sending and receiving through TCP/IP (Ethernet-based sending/receiving) and/or UDP/IP (lateral communication). Additional application layers can be implemented by downloading them on the controllers. Simultaneous operation of TCP/IP, UDP/IP and application layer is also ensured.

The data distribution at the bus is based on the Ethernet switch. The max. data transmission rate is 10 Mbit/s for 10 Base T and max. 100 Mbit/s for Fast-Ethernet.

Twisted pair cables with RJ45 connector are used as transmission medium. The maximum cable length is 100 m at a maximum transmission speed of Mbit/s.

Detailed diagnostic messages for rapid fault localization can be retrieved via the diagnostic interface and/or the Freelance Engineering software.


Section 1 Overview Fieldbus

Fieldbus

PROFIBUS®

PROFIBUS-DP is designed for rapid data exchange in the field area. Central control units communicate with decentralized field devices like remote I/O, transmitters or drives etc. using a fast serial connection. The data exchange with the distributed modules is mainly performed on a cyclic basis. PROFIBUS-DP is optimized in terms of high speed and simple device connection. This protocol variant is specifically designed for the communication between programmable controllers and a distributed I/O level. The AC 900F controller supports PROFIBUS Master redundancy.

For additional information on PROFIBUS-DP and the PROFIBUS CI/CM modules, please refer to Section 3, Modules as well as to the Engineering Manual, Communication and Fieldbusses.

Modbus

Numerous automation systems support the Modbus protocol by default or as an optional feature. This ensures easy communication with the AC 900F process station via on-board SER interfaces using the RS232/RS485 standards (MODBUS®) or TCP/IP (MODBUS TCP®). The Modbus protocol also ensures process data exchange with other systems via the serial or the Ethernet interfaces of the AC 900F.

This protocol allows data to be transmitted in either master or slave mode. For the configuration with serial interface, a specific MODM_DEV interface object must be assigned in the hardware structure. The interface-specific parameters are defined in this block.

For the TCP configuration (Ethernet), a specific MTCP_DEV interface object must be assigned in the hardware structure.

Please refer to the Engineering Manual, Communication and Fieldbusses and the Engineering manual, System Configuration, Hardware Structure for more detailed information.


Fieldbus Section 1 Overview

Telecontrol protocol

The function blocks of the telecontrol library are designed for the connection between the Freelance Engineering tool and external systems. The link is made via the serial interface (RS-232) or the Ethernet interface of the CPU module. The telecontrol protocol complying to IEC 60870-5-101 (serial)/IEC 60870-5-104 (TCP/Ethernet) is used.

For the serial interface, the telecontrol protocol provides device modules for symmetrical data transmission (FWK_DEV), asymmetrical data transmission as a master (FWK_DEV_M) and asymmetrical data transmission as a slave (FWK_DEV_SL). These modules are configured in the hardware structure. Please refer to the Engineering Manual, System Configuration, Hardware Structure for more detailed information.

For Ethernet-supported communication, the Ethernet interface and the parameters of the IEC 60870-5-104 compliant protocol must be set in the FWK_DEV_104 function block designed for telecontrol connection in the Ethernet network. The FWK_DEV_104 device module can be configured in the hardware structure below the Ethernet interface of the AC 900F.

ABB CAN Bus protocol

The CAN Bus of the AC 900F controller is intended to be used for connecting rack-based Freelance I/O modules only. With this feature, the current AC 900F controller CPU modules of type PM 902F/901F can alternatively take over the tasks of the CPU module types DCP 02/10 of the Freelance rack system.


Section 2 Configuration

This section provides information on the AC 900F controller configuration for single and redundant operation.

The AC 900F controller features a modular design. The basic components are a PM CPU module, CI/CM PROFIBUS communication interfaces and S700 I/O modules. The external 24 VDC voltage required to operate the controller can be provided by a CP-C power supply unit, for example.

Configuration levelsThe AC 900 F controller in basic configuration comprises the PM CPU module and two TA dummy couplers designed to protect the unused C1/C2 slots. The on-board Ethernet interfaces and serial interfaces of the CPU module are available for field communication.

AC 900F_only CPU.png


Configuration levels Section 2 Configuration

The controller of the medium configuration level is composed of a PM CPU module and up to two CI/CM modules for PROFIBUS communication. Alternatively, a CAN Bus module can be plugged into one of these two slots.

Medium configuration.png

The high configuration level controller is composed of a PM CPU module and up to two CI modules for PROFIBUS communication. Alternatively, a CAN Bus module can be plugged into one of these two slots. S700 I/O modules are used as “direct I/O”.

AC 900F_ Controller.png


Section 2 Configuration Controller redundancy

The S700 I/O modules are connected on the right side of the I/O bus, i.e. they are simply plugged to the TU terminal blocks that were previously added to the CPU modules. Up to ten I/O modules can be connected to the I/O bus of the CPU module.

The configuration in the Freelance Engineering hardware structure should correspond to the actual controller configuration (local DIN rail). Make sure that there are no blank TU terminal blocks between the individual I/O modules. I/O modules connected on the right side of a gap (i.e. of a blank terminal block) are not controlled by the CPU module.

Controller redundancy Two controllers of identical configuration - hereinafter referred to as redundant controllers - are used for redundant operation. While the active controller has the “Primary“ status, the “Secondary“ status is assigned to the other controller. During normal operation, the primary is the active controller and the secondary the passive one (hot standby).

For synchronization purposes, a point-to-point Ethernet connection (100 MBit/s) must be established between the controllers. This connection is also referred to as redundancy link.

A redundant configuration may be composed of two controllers of basic or medium level configuration. Make sure to use only the CI 930F, CI 910F or CI 773F communication interface modules for the medium configuration level as only these module types are suitable for redundant operation.

The S700 Direct I/O and the CM 772F communication module are not supported with redundant controller arrangement.


Controller redundancy Section 2 Configuration

If the primary controller (Primary) fails, the secondary controller is activated via a designated communication connection (redundancy link).

The cyclical adjustment ensures smooth change over from the primary to the secondary controller, i.e.

• the outputs of fieldbus-connected I/O components are maintained.

• the internal status (component data, variables) is maintained.

• the configuration and operating data of the primary and secondary controllers are automatically adapted.

Section 3 Modules

This section provides information on the features and interfaces of the various AC 900F modules.

The parameter data have a direct effect on the module functionality. For more information on module configuration and parameter setting refer to Engineering Manual, Process Stations, and Engineering Manual, System Configuration, Hardware Structure.

PM CPU modulesThe PM CPU module is the basic component of the AC 900F controller. It comes with a high-performance processor for multitasking and for processing tasks with short cycle times.

The module is equipped with three or four on-board Ethernet network connections of 100 Mbit/s and two serial interfaces. A third serial interface is provided for diagnostic purposes and for the connection of a radio clock.

Additional modules can be added on the left and right sides of the CPU module using the coupler bus slots and an I/O bus interface.

The TD display unit shows the system status and diagnostic data directly at the module. The operating mode can be changed using the switches provided on the front panel of the CPU module.

The following instructions must be thoroughly read and observed to ensure safe operation.

• Make sure that the maximum supply voltage (see Section 9, Technical Data) for modules, sensors and other devices is not exceeded. A module supply voltage of more than 30 V DC may lead to irreversible damage and destruction of the system.

• Incorrect wiring (e.g. +/- of the power supply is connected to both L+/L+ or M/M) will cause a short circuit. This may trip the fuse of the power supply unit or damage the switch-mode power supply unit. For general information on safety and precautionary measures, please refer to the Safety Instructions for the AC 700F/AC 900F.

Ethernet interfaces

The on-board Ethernet network interfaces of 100 Mbit/s can be used for communication between the controllers, gateways, control station and engineering stations as well as for Ethernet-based field devices to support Modbus TCP or telecontrol protocol as per IEC-104.

Unused slots must be covered with TA dummy couplers to comply with the ISA 74.01 G3 requirements.

I/O bus

The I/O bus on the right side of the PM CPU module is provided for communication with I/O modules that are directly connected to the CPU module. This bus serves for exchanging I/O data and diagnostic data between the CPU module and the I/O modules.

IO_Bus_us.png


LED display and control elements Section 3 Modules

Up to 10 TU I/O terminal blocks (one block per I/O module) can be added to the CPU module. For this purpose, the I/O terminal blocks are equipped with a male connector on the left and a female connector on the right side.

LED display and control elements

LEDs and switches

The LEDs on the front panel show essential status information and diagnostic data. The operating mode can be changed using the switches.

LED Color Status Meaning

PWR Green ON Power supply correctly connected, 24V DC voltage is applied

OFF No supply voltage

Power supply not correctly connected

ERR Red ON Hardware error during self-test

Flashing Error occurred, LED continues to flash until the sys-tem is stopped or started again

OFF No error

RUN Green ON AC 900F is operating RUN

Red ON AC 900F was stopped STOP


Section 3 Modules LED display and control elements

Three switches are provided for the following functions:

– RUN/STOP

– TOGGLE (Primary/ Secondary)

– RESET

RUN/STOP switch

This switch is used to start and stop the program sequence. In redundant mode, the position of the RUN/STOP switch on the active AC 900F is used.

P/S Green on Primary

ON In redundant configurations, the active AC 900F is referred to as Primary.

Synchronous operation as normal state

Flashing Non synchronous operation as transition state; oc-curs when the data are not aligned with the Sec-ondary

Orange on Sec-ondary

ON Synchronization mode

Flashing Synchronization on

Red on Second-ary

ON Redundancy synchronization failed

OFF No redundancy configured

BATT Green ON Sufficient battery capacity for the indicated buffer-ing time

Red ON Battery test during power-up

Empty battery

Battery not connected

Orange ON The battery must be replaced.



LED display and control elements Section 3 Modules

Both controllers perform the command (Run or Stop). The LED display on the Primary shows the current status. In the case of a redundancy change-over, the last status is retained irrespective of the RUN/STOP switch position.

Change-over to Run Normal operation. The program sequence is started. If the module is reset and a self-test is subsequently started, no configuration menu appears at the diagnostic interface.

Change-over to Stop The program sequence is stopped. If the module is reset and a self-test is subsequently started, the configuration menu appears at the diagnostic interface.

TOGGLE switch

With a redundant AC 900 F configuration in synchronized state, a change-over of the TOGGLE switch on the Primary produces the following effect: The previous Secondary changes immediately to Primary and the previous Primary to Secondary without requiring any system rebooting. Any actuation of the TOGGLE switch on the Secondary will be ignored.

RESET switch

The RESET switch is used to reset the AC 900F. Depending on the system status, either a warm or a cold start is initiated. A “tool“ (e.g. a ball pen or similar) is required to actuate the RESET switch.

When the RESET switch is pressed for a specified time, the following functions will be released:

Single controller < 4 s = Warm start > 4 s = Cold start

Redundant controller < 4 s = no function > 4 s = redundancy change-over and cold start of the controller with actuated RESET switch


Section 3 Modules Battery

SD card reader

The SD card reader is used for data backup, for restoring the application as well as for updating the firmware. All high-quality SD cards with up to 32 GB are supported. With an appropriate adapter, micro SD cards can be used as well.

Battery

The optional battery serves for saving the SRAM contents (e.g. process and configuration data) in the event of power failure and to supply the real time clock.

The CPU module monitors the battery status (capacity). A low battery capacity warning is displayed before data storage is at risk (about 2 weeks in advance). Upon this warning message, the battery should be replaced as soon as possible. For more detailed information, please refer to Section 4, Accessories.

Display unit

The PM CPU module supports the TD 951F display as an optional accessory. Remove the front panel to install the display unit to the PM CPU module. For more detailed information, please refer to Section 4, Accessories.

CI/CM PROFIBUS modulesThe AC 900F is designed for operation with different PROFIBUS communication interfaces like the CI 930F, CI 773F and CM 772F that can be connected on the left side of the PM CPU module.

PROFIBUS communication interfaces ensure communication via the PROFIBUS-DP fieldbus. The internal coupler bus connects the CI/CM with the CPU module. This applies to data and power supply. A dual-port RAM is used for data exchange.

CI 930F PROFIBUS-DP Master Interface

The CI 930F provides two on-board PROFIBUS interfaces A/B for increased availability regarding PROFIBUS communication.

CI 930F_us.png

Data arriving at CI 930F via the coupler bus are routed in parallel to both A and B connections.

Data arriving to CI 930F via the controller coupler bus are routed in parallel to the two PROFIBUS terminals A and B.The first data coming in over line A or line B with a correct telegram start are routed to the coupler bus. With simultaneity, either line A or line B is selected at random. Testing and selection is always based on the first character. In the case of a telegram start with error on A, the control logic in CI 930F switches to the redundant line B. The same procedure applies vice-versa for line B.

General description

Operating status display

The green “OUTPUT OK“ LED lights up during operation.

Adjustment of the output voltage

Using the “OUTPUT adjust“ potentiometer, the output voltage can be adjusted within the range of 22 to 28 V.

Parallel operation

In order to increase capacity or to ensure redundancy, devices of the same type can be connected in parallel. To ensure symmetric current distribution, the line connections should feature identical cross-section and length.


Switch-mode power supply units CP-C 24/5.0 and CP-C 24/10.0 Section 3 Modules

Parallel operation, increase in capacity

For “n” number of power supply units connected in parallel the output current can be increased to “n x Ir”. A parallel connection is recommended if the power supply unit is not rated to provide the power required for the most powerful consumer load. In this case, the consumer load should be supplied by several independent power supply units. Up to max. 5 devices of identical type can be connected in parallel.

CP_C24_parallel_operation_capacity.png

Parallel operation, redundancy

Redundant circuits are used to increase the operational reliability of the system in case of errors (e.g. incorrect wiring, fuse trip in primary circuit, failure of individual devices). If a fault occurs in the first power supply circuit (referred to as initial fault), all loads are supplied by the second redundant circuit. For this purpose, the power supply units connected in parallel are rated such as to ensure that the total power requirements of all loads can be entirely covered by a single power supply unit.

Key Description


TA 951F battery for RAM buffering Section 4 Accessories

Use

The TA 951F lithium battery serves to supply the real time clock and the SRAM in order to save the memory contents (e.g. process and configuration data) in the event of power failure. The CPU module is delivered without lithium battery. A new TA 951F battery must always be inserted during initial start-up of the CPU module.

After longer voltage supply interruptions at the CPU module (maintenance operations, shut-down, transport or similar), a new battery must be installed as well in order to ensure the specified buffering times.

Although the CPU module can also be operated without battery its use is strictly recommended in order to avoid data loss.

The CPU module monitors the battery voltage and thus indirectly also the battery capacity (charging status). The “Low CPU module battery capacity” message is issued when the capacity has reached a level that is sufficient for 14 days buffering. The battery should be replaced at regular intervals and as soon as possible after the low battery warning has been displayed.

The TA 951F lithium battery is the only battery type that is compatible with the PM CPU module. It is a non-rechargeable primary cell.

Safety instructions

Risk of overheating and subsequent explosion!

The battery must only be replaced with the controller supply voltage ON in order to avoid any data loss.

Data buffering is not possible without a battery when the supply voltage is switched off.

B

Batteries must not be short-circuited, recharged, opened or thrown into fire!

Store the batteries in a dry place.

Strictly observe the applicable local recycling and environmental regulations during disposal of used batteries.

Suitable dowels and screws (e.g. 4 x 50 mm) must be selected depending on the wall material at the place of installation.

AC 900F_wall accessory_3.png

The enclosed mounting set (red parts) is intended for both upper screws. Both plastic tubes are designed to bridge the gap between the plastic housing and the wall. Insert the nose of these tubes into the bore provided in the plastic housing.


Section 5 Mounting TU terminal blocks

TU terminal blocks

When using a direct I/O, the corresponding number of I/O terminal blocks must be connected on the right side of the CPU module using the previously attached accessory part. The TA526 accessory part for wall mounting prevents any deformation of the terminal block during fixing to the wall. It is recommended to mount the terminal blocks in small groups of up to three units. After having marked the correct position and drilled the bores, the terminal blocks can be fixed by means of screws. Use two M4 screws per terminal block for this purpose. The screws must be inserted at the terminal block front.

Coupler bus slots Section 5 Mounting

Coupler bus slots The C1 and C2 coupler bus slots serve for connecting the CI/CM communication interfaces to the CPU module. When configuring the AC 900F controller and integrating a CI/CM module, the bottom module part must be plugged in first. Then press the module backwards until it locks in place at the top of the slot.

Coupler bus C1-C2_us.png

A TA dummy coupler is installed and removed from the C1/C2 slots as described for a communication interface.

The module change during operation is described in Section 8, Service.

Section 6 Wiring

This section provides information on wiring the AC 900F controller exclusive of the CI/CM communication interface module. It contains safety instructions, general guidelines and information on cable routing.

Safety instructions

The L+ and M terminals are assigned twice. Incorrect wiring may cause short circuits and damage the power supply unit or the fuse protection of the power supply unit. If no suitable protection is provided (suitable module), the CPU module may be damaged as well. For this reason, the CPU module must be wired in compliance with the following instructions and an adequately dimensioned fuse must be used.

General instructionsStrictly observe the following basic principles and instructions when installing and wiring the controller.

Make sure to strictly observe the following safety instructions when wiring the controller. This requirement is essential to exclude personal injury and equipment damage.

Please refer to the safety instructions for the AC 700F/AC 900F for general information on safety and precautionary measures.

The specified earthing and shielding measures must be implemented in order to ensure reliable controller operation.


Controller earthing Section 6 Wiring

• Keep all connecting lines as short as possible. This is particularly important for the earthing conductors.

• Make sure to select sufficiently dimensioned wire cross-sections. This is particularly important for earthing conductors.

• To achieve low-impedance, i.e. optimum contacts over a large surface, proceed as follows:

– establish vibration-resistant connections,

– use bare contact areas (remove paint, clean surface),

– avoid the use of aluminum parts (oxidize easily),

– select solid plug and screw connections,

– directly earth the cable shields with clips to a well-grounded metallic surface,

– do not use drain wires (pig-tails),

– do not use toothed washers to lock the screw unions.

Contact_us.png

Controller earthingProper earthing of the controller requires an earthed mounting plate or metal frame. Additional earthing measures are only required if the mounting surface or frame material cannot be earthed. In this case, a short earthing conductor must be connected to the lower left/right fastening screw of the CPU module. l

The controller is earthed through the DIN rail or both lower fastening screws. Use yellow chromated steel DIN rails to ensure proper earthing.


Section 6 Wiring Cable routing

Cable routing• Ensure proper cable routing during wiring.

• Sort the cables in different cable groups (power current cables, power supply cables, signal cables and data cables).

• Make sure to lay signal and data cables separately from power current cables, i.e. in separate conduits or cable bundles. The distance should be at least 20 cm.

• Signal and data cables should be installed close to earthed surfaces.

Cable shields• Use only shielded data cables. The shield must be earthed on both sides. Make

sure that no compensating currents pass through the cable shield. A current-carrying equipotential bonding line can be used for this purpose.

• If a cable shield is earthed on one side, it only provides protection against capacitive coupling and low-frequency interference (50/60 Hz ripple voltage).

• Only use braided-shield cables. Foil shields exhibit low mechanical stability as well as poor contact and HF properties.

• Only metallic or metal-coated connectors must be used for shielded data cables.

• Use only shielded cables for analog signals. Earth the shield on one end only for the transmission of small signals.

• Earth the cable shield using a clamp directly at the entry into the switch cabinet. Guide the shield up to the module without any interruption.

• There must be a low-impedance connection between the PE bar and the shield bar.


Switch cabinet Section 6 Wiring

Switch cabinet• Low-impedance connections between the switch cabinet, mounting plate,

earthing bar (PE) and shield bar must be provided.

• Earth the switch cabinet doors on the sides using short and highly flexible conductors.

• To protect the control system against interferences, only bulbs or interference-suppressed fluorescent/LED lamps should be used in the direct vicinity of the control system for switch cabinet lighting.

• If an interference immunity of 6 kV instead of 4 kV is required, the controller must be installed in a switch cabinet and operated exclusively with the door being closed.

Minimum distances• Provide for adequate distances to the switch cabinet walls, cable conduits,

adjacent devices, etc. There should be a distance of 20 mm around the controller to all sides in order to ensure proper ventilation and electrical insulation.

• Horizontal installation is highly recommended. Vertical mounting is also possible, but involves restrictions in terms of performance due to insufficient air circulation, which causes heating of the devices.

• When mounting the system in vertical position, mechanical stops must be provided at the top and the bottom to protect the modules against vibrations. For applications with high levels of vibration, the installation of mechanical stops on the left and right sides is also recommended for horizontal mounting in order to efficiently protect the modules against vibrations.

Reference potential• Ensure a uniform reference potential throughout the line and earth the complete

electrical equipment, as far as possible.

• Install the earth conductors in star configuration to avoid the formation of ground loops.

7 Earthing of the 0V rail


Power consumption Section 6 Wiring

• Install sufficiently dimensioned equipotential bonding lines if high potential differences between the system components are present or expected to occur with your specific application.

• The impedance of the equipotential bonding line should amount to maximum 10% of the shield impedance of shielded signal lines between the same points.

• The cross-section of the equipotential bonding line must be rated for the maximum compensating current. Experience has shown that a cross-section of 16 mm² is usually sufficient.

• Equipotential bonding and shielded signal cables should be laid as close as possible to each other to prevent the formation of inductive loops and the risk of interference coupling.

• Ensure low-impedance connection between equipotential bonding lines and PE.

Power consumption The total power consumption of the controller corresponds to the sum of all individual consumption values. The following values must be taken into consideration:

• the power consumption of the CPU module through the L+ and M terminals. After voltage conversion within the CPU module, the communication interfaces and the bus-connected I/O modules are supplied from here as well.

• the power consumption for the process supply voltage at the ZP and UP terminals of the terminal blocks. The power for the consumers at the digital/analog outputs and the electronics inside the I/O module is also supplied from here.

Section 6 Wiring Fuse dimensions

A single power supply unit can be used for both supply voltages. The CPU module and the I/O modules should, however, be provided with separate fuse protection. As a matter of course, separate power supply units can also be used.

Fuse dimensionsTo select the appropriate fuses for the station, the power consumption and the inrush currents (melting integral of the upstream fuse) must be taken into account.

Bus termination Section 6 Wiring

Bus termination

Serial interfaces of the CPU module

Interface standards

Serial interfaces comply with the EIA RS-232 and EIA RS-485 standards.

Serial interfaces (SER1 and SER2) for the CPU module

Serial interface_ser1_ser2_us.png

The SER1, SER2 serial interfaces are connected by means of a removable 9-pin terminal block. They can be configured for RS-232 or RS-485 and used e.g. for Modbus (master / slave).

If the RS-485-bus is used, each connected bus line (each bus segment) must be electrically terminated. This includes:

• one 120 Ohm bus terminating resistor on both wire ends (to avoid signal reflections).

• one additional 470 Ohm pull-up resistor on RxD/TxD-P and one 470 Ohm pull-down resistor on RxD/TxD-N per bus. These two resistors are designed to ensure a defined high level on the bus when no data are transmitted.

• shielded twisted-pair cables with an impedance level of 100 to 120 Ohm.


Section 6 Wiring Serial interfaces of the CPU module

The two 470 Ohm resistors are integrated into the CPU module and can be activated by a short wire link between the terminals 1-2 and 3-4. The following drawing shows an RS485 bus with a bus master at the line end.

RS 485 bus_us.png

If the master is located within the bus line, a terminating resistor is not provided. The pull-up resistor and the pull-down resistor, however, need to be activated (see drawing below). The cable shields of the bus line must be earthed.

RS-485 Bus_bus line_us.png

Ethernet_Connect_us.png

The external 120 ohm resistor (line termination) must be protected against electrostatic discharge. It is recommended to provide the complete resistor (except for the wire ends) with a heat shrink tube for this purpose.


Serial interfaces of the CPU module Section 6 Wiring

Redundant controller

The RS232/485 bus lines of a redundant controller should first be connected to terminal strips and then be guided to the field. The terminal strips must be arranged as close as possible to the controller. In this configuration, the pull up/down resistors of the CPU module are not required.

RS232

RS 232 redundant PM.png


Section 6 Wiring Serial interfaces of the CPU module

RS485

RS485 redundant PM.png

A regulated power supply with output voltage 5 V DC +/- 10% is needed to provide for a defined quiescent level on the RS484 bus. .

The 5 V DC power supply unit must have a safe electrical isolation. As described earlier in this section, the external resistors must be protected against electrostatic discharge.


Serial interfaces of the CPU module Section 6 Wiring

Ethernet

The CPU module features several on-board Ethernet interfaces. As far as the maximum line lengths in Ethernet networks are concerned, various factors must be taken into consideration. With twisted pair cables (transmission rate of 10 Mbit/s and 100 Mbit/s) for instance, the maximum length of one segment, i.e. the maximum distance between two network components is limited to 100 m due to the electric properties of the cable.

In addition, the length limitation for one collision domain must be observed. A collision domain is the area within a network that may be affected by a potential collision. However, this must only be taken into consideration if the components are operated in half duplex mode, as the CSMA/CD access process is only used in this case. If all components work in full duplex mode, no collisions will be caused.


Section 7 Commissioning

This section provides information on the basic operations required for first commissioning of the controller.

Data backup Data backup is not possible without a battery when the supply voltage is switched off.

.

To insert the battery, proceed as described below.

Insertion of the TA 951F battery

Remove the detachable front panel of the CPU module or the display unit installed in this position. The following drawing shows the mounting position of the battery behind the fixed housing front part. The new CPU module housing has been equipped with a battery compartment that replaces the previously used battery holder.

Module with battery compartment (new)

Push the battery to the left into the battery compartment. It will be locked in place by the front panel or the display unit.

The use of unsuitable batteries leads to explosion or fire hazards. This is why exclusively TA 951F lithium batteries must be used for the PM CPU module.

As soon as the battery is connected and the controller is not supplied with operating voltage, buffering and battery unloading are started.


Insertion of the TA 951F battery Section 7 Commissioning

Module with battery holder

Place the battery in inclined position onto the lower holder. Press the battery downwards and then to the left until it locks in the upper holder. Both holders are provided for locking purposes only; they are not electrically connected to the battery.

To connect the battery to the power supply, plug in the battery connector into the mating socket. The connector is keyed to ensure reverse polarity protection. Close the housing with the previously removed front panel or display unit.

Section 8 Service Maintenance menu

F1 - Module exchange

This function supports the CI module change with the controller being in operation. The current ON/OFF status of both C1 and C2 slots is displayed.

Press the F3 (C2) or F4 (C1) function key to change the status. Change back to ON after a module change has been performed in OFF state.

Module exchange.png

F2 - Backup config

The controller writes a copy of the loaded configuration (application) on the SD card. This function is only activated on condition that an application is running on the controller and an SD card is inserted.

Save application.png

As soon as the process is completed, an OK message appears on the display.

The file with the backup copy has the name <IP Address>.CFI, with the IP address being indicated in hexadecimal format. During the saving process, the controller remains in operation, but downloads are rejected.

The parameter/variable values that were temporarily changed by Write or Force in the application and thus on the controller will not be saved on the SD card.


Maintenance menu Section 8 Service

F3 - Save memory image

The controller writes a copy of its memory contents on the SD card. This function is only activated on condition that an application is running on the controller and an SD card is inserted.

Write memory image.png

As soon as the process is completed, an OK message appears on the display.

The file with the memory contents has the name <IP Address>.MEM, with the IP address being indicated in hexadecimal format. During the saving process, the controller remains in operation, but downloads are rejected.


Section 8 Service Offline functions of the display unit

Offline functions of the display unitThe following information refers to functions that can only be performed offline. For this reason, the controller must be in Boot Configuration mode.

In order to activate the configuration mode of a controller during operation, the controller supply voltage must be switched off and on again with the ESC key being pressed and held during restart.

Boot Config.png

Update/Restore

The menu (Update/Restore) provides three F1 - F3 functions.

Restore.png

F1 - Restore config

The controller searches the configuration (application/project) on the SD card under the file name that corresponds to the IP address in hexadecimal format.


Update/Restore Section 8 Service

F2 - Firmware update

The controller searches a valid firmware file on the SD card and loads it into the flash memory of the CPU module. Upon restoring or updating, the controller is automatically rebooted. Depending on the file size, this process can take several seconds (loading..... is displayed). As soon as the ABB logo appears, you can remove the SD card from the slot.

F3 - Enable autorestore

The controller can be configured to automatically restore the configuration data saved on the SD card (Backup config) when a cold start is initiated.

The Autorestore function can only be properly performed on condition that the SD card with the configuration remains installed. The controller features a monitoring function to check whether this is the case. This monitoring function can be activated using the AC 900F parameter dialog in Freelance Engineering, only:

CPU/Security > SD card > SD card monitoring

If the SD card is removed while the monitoring function is activated, the controller displays a “SD card removed” message. This message appears in the Freelance Operations message list.

In the Freelance Engineering Commissioning mode the AC 900F parameter dialog shows the following:

[...] SD card available: [ ] = no card, [v]= card available

As to the use of the Autorestore function, please observe the following information.

CPU module with battery

In the case of a cold start and an empty memory, the data will be automatically transferred from the memory card to the controller memory. If the controller already contains data, the data from the memory card will not be stored.

Make sure that the SD card is not removed and the power supply is not switched off during firmware updating!


Section 8 Service Update/Restore

CPU module without battery

This AC 900F operating mode is recommended with regular supply voltage failures for a longer period of time, e.g. with solar energy supply. As no energy is supplied at night (buffering mode), the battery would be discharged within less than two years.

In order to ensure that after a control start the controller operates with the data from the memory card and not with “partly” still available data in the memory, a minimum turn-off time of the controller must be observed. The turn-off time (discharge of the buffer capacitors in the CPU module) must be > 60 s.


Update/Restore Section 8 Service
