INTRODUCTION 1-1


1. INTRODUCTION

SPiiPlus motion controllers have a unique High-Speed Synchronous Serial Interface (HSSI) bus, which facilitates expansion and provides a cost effective way to implement a distributed system.

The HSSI protocol is open for the user to design and build his own HSSI Modules to interface with the controller according to some special application needs.

The following SPiiPlus products support the HSSI bus:

• SPiiPlus PCI-4/8

• SPiiPlus PCI-DDM4

• SPiiPCI-4/8

HSSI COMPONENTS 2-1


2. HSSI COMPONENTS

2.1. HSSI-Hub The HSSI-Hub is a distribution board for up to four HSSI channels. The HSSI-Hub may be used as a unit between the controller and any HSSI module.

The HSSI-Hub is typically installed inside a PC where the SPiiPlus PCI / SPii PCI is located.

The HSSI-Hub has following connectors:

• One 30-pin connector to communicate with the SPiiPlus PCI-4/8 controller

• One 20-pin connector to communicate with SPiiPlus PCI-DDM4 controller

• Two 10-pin connectors to communicate with the SPii PCI controller

• Four RJ45 receptacles for HSSI Cables

FIGURE 2-1 HSSI-Hub

2-2 HSSI COMPONENTS


2.2. HSSI Cables Cable: FTP category 5 that is commonly used for Ethernet communication.

The total cable length must be limited to 20 meters. When daisy chaining, the sum of length of all cables must be limited to 20m.

2.3. Address Switch Settings To prevent contention while transmitting data to the motion controller, each unit is allowed to transmit at specific time. Any of the 4 Addresses can be selected from the switches. The Address also defines the relevant bits for reception.

Every HSSI-IO16 unit in the chain has a different Address.

In Command Mode the HSSI-IO16, regardless of the Address assignment, interprets all 64 bits.

3.3. HSSI-IO16 Mounting Options • DIN Rail Mount – for DIN rail mounting use the standard supplied plastic side elements.

• Surface Mount - for surface mounting use the supplied metal side elements. Mount the modules with the supplied screws to the surface.

3.4. Daisy Chain Wiring of Modules To increase the number of inputs and outputs available to the system, HSSI-IO16 units can be daisy chained. Up to 4 units can be chained on each HSSI channel. Each unit has two RJ45 connectors for easy chaining. Total length of the daisy chain should not exceed 20m. For HSSI Cable specifications refer to section 2.2 HSSI Cables.

3.5. Input Structure The I/O stages get their power from a user supplied DC power source. If isolation is not needed, the system 24V(-20% +10%) power supply can be used instead, by making an external connection.

The input stage is versatile and can be configured as sink or source by making the following external connection:

• Source – Connect input connector pin-18 (REF) to pin-19 (VIN_RET)

• Sink – Connect input connector pin-18 (REF) to pin-20 (VIN)

3.6. Output Structure The HSSI-IO16 has 16, opto-isolated outputs.

The outputs source type and are divided into two groups: Outputs 0-7 and Outputs 8-15. The total current available to each group is internally limited to 350mA. Thus, the HSSI-IO16 can supply 350mA to 2 loads, 175mA to 4 loads, or 43mA to 16 loads.

SOFTWARE SUPPORT 4-1


4. SOFTWARE SUPPORT

The following chapter explains the basic software support to provide the following functionality:

• How to get started

• How to designate channel and module numbers

• How to read an HSSI input in each module

• How to assign an HSSI output in each module

• How to interrogate and verify communication by getconf function

• How to diagnose HSSI-IO16 communication by setconf function

• How to use the SPiiPlus MMI, I/O monitoring tools for the HSSI-IO16

• How to use the SPiiPlus MMI, Scope to monitor the HSSI-IO16

4.1. HSSI-IO16 Operation • How to write and read an output: Use the proper array element of ETXOUT.

Example Assuming that an HSSI-IO16 is connected to channel 0 and its address is 2. To set output 0: EXTOUT2=0x1 To set all outputs: EXTOUT2=0xffff To read the status of the outputs: ?EXTOUT2

• How to read an input. Use the proper array element of ETXIN. Example (assuming the above setup): ?EXTIN2

4-2 SOFTWARE SUPPORT


• How to find out which module types are connected and their status by using getconf. Example Two HSSI-IO16 units are connected to channel 3 with Address 0,1(12,13) getconf(24,12) -returns 0, unit is connected getconf(24,13) -returns 1, unit is connected getconf(24,14) -returns -1, no unit is connected getconf(24,15) -returns -1, no unit is connected

• How to recover from communication fault. When an HSSI Expansion Module detects communication failure, it turns all outputs off and turns the communication LED to red. Usually it happens if the communication cable is disconnected. To reinitiate the unit(s) issue the getconf command to all units that are connected to that channel. Example 4 modules are chained to channel 0 and the cable between unit 1 and 2 was disconnected. The communication LED of units 2 and 3 will turn red. After reconnecting the cable, issue the following commands: getconf(24,0) getconf(24,1) getconf(24,2) getconf(24,3)

• How to switch between Command Mode and Data Mode. When in Data Mode, the bits EXTOUT3.15,,,,, are always sent as 1 to the modules. In command mode it is possible to address the HSSI expansion modules using low level protocol and commands, via the EXTOUT/EXTIN arrays. EXTOUT3.15, EXTOUT7.15, EXTOUT11.15 and EXTOUT15.15 are sent to the modules as is. To switch to Command Mode, use the setconf command. Example To switch to Command Mode the module that is connected to channel 0 with address 2: setconf(24,2,1) To switch to Data Mode: setconf(24,2,0)

4.2. Designate Channel and Module Numbers Each HSSI-IO16 module has identification switches that assign to the module a number from 0 to 3. The modules connected to one channel must have different numbers. Module designations include channel number and module number (for example, module 1:3 means the module number 3 connected to channel 1).

There are 4; 16-bit input registers per HSSI channel. The registers are designated 0, 1, 2, and 3. The input registers are represented by the EXTIN array of 16 elements. Each element contains 16-bits. The EXTIN array is Read only except in the simulator where they are Read/Write.

There are 4; 16-bit output registers per HSSI channel. The registers are designated 0, 1, 2, and 3. The input registers are represented by the EXTOUT array of 16 elements. Each element contains 16-bits. The EXTIN array is Read/Write.

Up to 4, HSSI-IO16 Expansion Modules can be connected to each channel. The Address of each unit must have proper EXTIN and EXTOUT arrays.



Bit-15 in each channel is used for command identification. Therefore, bit-15 is not transferred to the device and is not available: EXTOUT3.15, EXTOUT7.15, EXTOUT11.15, EXTOUT15.15, etc.

EXTOUT15.3 = 1 Set output 3 in module 3:3 to 1

EXTOUT2 = EXTIN0 Read all 16 input bits of module 0:0 and assign to all 16 output bits of module 0:2

EXTIN0.1 = 1 The assignment is senseless in actual controller, but can be used in Simulator for input emulation

4.4. HSSI Module Interrogation (getconf function)

The getconf function does the following:

• Tests communication integrity

• Identifies module type

• Switches to Data Mode and turns led green

The user application can interrogate the modules connected to HSSI channels in order to obtain their Address and to verify the communication during Operational or Command Modes.

The getconf function with key 24 provides information about the connected modules. The syntax of the function is: int getconf ( int Key, int Index ) where the Key argument must be 24 to interrogate the connected module, the Index specifies the interrogated module exactly as the index in EXTIN/EXTOUT arrays does.

The function returns an integer number that specifies the following:

• Positive number represents the module Address and means that the module is functioning properly. Address of the HSSI-IO16 module is 1.

• Value –1 means that no module is connected that corresponds to the specified index.

• Negative value indicates failure of the module test. Either units with the same address are connected to the same channel, or communication failed

For example, if the function getconf(24, 12) returns –1, no module is connected to HSSI-IO16 channel 3, Address=0

If the function finishes successfully and returns positive number, the controller transfers the module to Data Mode and switches the communication LED to green.



The GETCONF function can be used periodically to check the integrity of the modules. The GETCONF command execution takes up to 10millisecond. During that period, the outputs are not updated and the EXTIN array is not updated according to the state of the inputs.

The interrogation affects the communication with the interrogated module and with other modules on the same channel. For the time of interrogation (10 milliseconds) the modules does not update their outputs with the bits of EXTOUT array and does not update the EXTIN arrays according to the state of their inputs. For example, execution of function getconf(24, 10) freezes for 10milliseconds all operations in modules 2:0, 2:1, 2:2, 2:3.

4.5. Switching Between Modes (setconf function) When setting the HSSI communication channel into diagnostic mode, then it is possible to address the modules that are connected using low level protocol and commands, via the EXTOUT/EXTIN arrays.

The setconf function gives an option to set an HSSI channel to Command Mode for entire communication check without a limit of time.

The setconf function with key 24, switches on/off the HSSI channel to Command Mode. The syntax of the function is: setconf ( int Key, int Index, int Enable ) where the Key argument must be 24 for mode switching.

Index specifies the module exactly as the index in EXTIN/EXTOUT arrays does. Enable accepts only two values: 1 set the HSSI channel to Command Mode and 0 set the HSSI channel to Data Mode (pending that the communication with the HSSI modules function properly).

Example setconf(24, 2, 1) sets the HSSI channel 2 in Data Mode

4.6. SPiiPlus MMI Support SPiiPlus MMI has a screen that allows monitoring and setting of values to digital I/O as follows:

• Digital Inputs (setting values can be done only with SPiiPlus Simulator)

• Digital Outputs

• External digital Inputs and Outputs in all optional 16 units of HSSI-IO16



4.6.1. I/O Monitor The I/O Monitor displays the desired I/Os (Onboard, External) as where selected in the I/O selection screen. The I/O Monitor provides indication of onboard IN0/OUT0 and all 16 EXTIN and EXTOUT array bits (all I/O of up to 16 HSSI-IO16 modules). To open the I/O Monitor press the I/O button in the SPiiPlus MMI main panel.

FIGURE 4-1 I/O Monitor screen In the I/O Monitor, circles present digital Inputs. Whenever a specific input is On, the representative circle is illuminated. The user can toggle each Input On or Off state by click the representative circle (besides the onboard digital inputs when the SPiiPlus MMI is not connected to the Simulator).

In the I/O Monitor, squares present digital outputs. Whenever a specific output is On, the representative square is illuminated. The user can toggle each Output On or Off state by click the representative square.



4.6.2. I/O Variables The Select I/O Variables screen appears after pressing the I/O button in SPiiPlus MMI main panel and then pressing Select I/O Variables. The I/O Variables screen allows the user to select the desired I/Os (Onboard, External) to be monitored in the I/O Monitor.
