Architecture

Overview The architecture consists of three main function groups:

• the Control Cabinet with operator interface • the Remote Cabinet with motor control • the Field Installation sub system

These three groups are described separately.

Layout Control Cabinet


Schneider Electric

6

Description Control Cabinet

The main components of the Control Cabinet are: • Twido Compact PLC (PLC) with AS-Interface Master Module • Magelis XBT-N compact operator terminal (alphanumerical display) • Optional: Emergency Stop Safety Module category 3, based on Preventa Safety

module and additional standard components The Control Cabinet contains the PLC, the HMI and the optional Emergency Stop safety module. Also, the 400 VAC power distribution and protection as well as 30/24 VDC power supply for control unit and AS-Interface network are implemented here. The HMI terminal is powered by the 24 VDC sensor supply output from the PLC. This has the advantage that the PLC and HMI work independently of the other system components and are therefore capable of detecting and reporting fault conditions in other components. The optional safety module implements an Emergency stop which causes motor power disruption. The power can only be switched on again after pushing the confirmation button to confirm safety has been restored. Power availability is indicated by the light inside the button.

Layout Remote Cabinet

and Field Installation

Description Remote Cabinet

The main parts of the Remote Cabinet are: • 6 TeSysU Motor Starters with AS-Interface (TeSysU) • 4 digital I/O-blocks IP20 with AS-Interface (IP20-I/O) • Optional: Emergency Stop switch (EStp) The TeSysU motor starters can be installed side by side and powered via power rails. This minimizes space requirements and cabling. The IP20-I/O-modules can also be installed side by side. The optional Emergency Stop switch is hooked into the Emergency stop loop originating from the Safety Module in the Control Cabinet. It allows you to initiate an Emergency stop from the Remote Cabinet’s location.

Field Installation The Field Installation consists of 3 digital I/O-blocks IP67 with AS-Interface (IP67-I/O). These blocks and their taps need no housings and can be installed as and where required.

Number of components

A detailed list of the required components, including quantities and part numbers, is included in the appendix of this document.

Degrees of protection

Not all of the components used within this configuration have been designed to withstand the full range of environmental conditions in the field. Some components will, therefore, require additional protection and are only suitable for installation in a control cabinet. For information on which components are suitable for direct installation on site, please refer to the list provided in the Appendix (column headed “In the field, on site”, which also indicates the relevant IP protection class).

Design data

Safety category Cat. 3 (optional)

Safety notice In this application example, Category 3 (according to EN 954-1) has been selected

for the purpose of ensuring safety. The issue of whether a safety category (1-4) should be adopted and, if so, which one, is determined by the system’s design and the overall extent to which this system represents a hazard to people and machinery. Safety category 3, based on EN 954-1, is the second highest category.

Size/ Dimensions

The components of the Control Cabinet can be installed inside a housing with approximate external dimensions of 500 x 500 x 210 mm (WxHxD). The Safety Module with the mains switch and circuit breaker is also intended to be housed here. The components of the Remote Cabinet can be installed very close together. The TeSysU motor starters are installed side by side and supplied via power rails. The IP20-I/O modules can also be installed side by side. The housing needed should have approximate external dimensions of 400 x 600 x 210 mm (WxHxD). The Field Devices with their taps do not need a housing. They are installed as and where required.

Installation

Introduction This chapter describes the steps required to assemble the hardware and install the

software to acheive the application task concerned.

Note This document does not claim to be comprehensive and does not absolve users of

their duty to check the safety requirements of their equipment and to ensure compliance with the relevant national or international rules and regulations in this respect. Safety category 3, which is suggested here as one possible option, is not necessarily required/adequate for every application, as a risk analysis must be drawn up and verified for each system in accordance with national and/or international standards and regulations.

General • The components designed for installation in a control cabinet, i.e., Twido PLC, Phaseo

power supply unit, Emergency stop safety module, line circuit breaker, contactors and motor circuit breaker, can be snapped onto a 35 mm DIN rail.

• Emergency stop, mains and maintenance switches are designed for backplane assembly in the field; all switches can also be installed directly in a control cabinet (e.g., on the control cabinet door) without their own housings.

• There are two options available for mounting XB5 push buttons and indicator lamps: 1. Using a 22 mm hole drilled into the front door of the control cabinet in the

appropriate position. 2. Using an XALD housing, which can house up to 5 push buttons or indicator lamps.

This XALD is designed for backplane assembly or direct wall mounting. • 400 VAC wiring between the master switch, the 24 V power supply unit (primary), as

well as the motor circuit breaker and motor starters and motors. • 24 VDC wiring between the power supply unit and the Safety Module. • AS-Interface power and Aux.-power 30/24 VDC via yellow and black AS-Interface

cables.

Implementation

Introduction This chapter describes how to install and set up the software for the task associated

with the following application.

Function Functional description

1. The whole application is controlled via the HMI in the Control Cabinet. 2. The installed hardware must be in operation mode:

- The components have to be installed properly. - The mains switch must be switched on. – All circuit breakers must be closed. – The motor starters must be switched on. – The Emergency stop components have to be acknowledged so that the foreseen safety level is achieved.

3. The HMI has six screens to observe and control the motor starters. Each screen shows the states of the motor starter (Ready/Run) and allows you to control the motor starter (Forward/Reverse).

4. The HMI has an additional screen to enable the outputs of the seven digital I/O-modules. Setting enable starts periodical on/off-toggle of the digital outputs LED indicators.

5. The left navigation button on the HMI switches between the motor starter control screens and the I/O control screen.

6. The right navigation button on the HMI cycles through all six motor starter screens.

HMI

Introduction This application features a compact Magelis XBT-N401 HMI,

that is interfaced with the PLC via the Modbus protocol. XBT-L1000 software is used to program and configure the terminal. The following pages explain this procedure.

Preconditions The following conditions must be met in order to carry out the steps described below:

• The XBT-L1000 configuration tool is installed on your PC • The “DP-ASI.dop“ project is available in the default directory that has been set up

(C:\Program Files\Schneider Electric\XBT-L1000\Apps). • The Magelis terminal is supplied with power from the Twido PLC i.e. the PLC has to

be switched on and supplied with power. • The Magelis terminal and the PC are linked to one another via the PC <> Twido

programming cable (XBTZ915).

Programming/ Configuration

1 When the XBT-L1000 program starts up, the configuration screen for creating a new application appears. Click "Cancel" to exit this dialog.

2 Select File -> Open to go to the default path: “C:\Program Files\Schneider Electric\XBT-L1000\Apps”. This is where the “DP-ASI(.dop)“ application should be stored. After selecting the application and clicking on Open, one of the configured screens from the HMI apllication will appear on the screen.

Simulation 1 The behaviour of the HMI

terminal can be simulated by selecting Simulation in the menu bar, followed by Simulation Application.

Transferring a program

1 In order to transfer the program from the PC to the terminal, the two must be connected with the XBTZ915 communication cable.

2 The application is transferred to

the Magelis terminal by selecting Transfers in the menu bar, followed by Export. Before the download begins, a message appears, which you should confirm with "OK". Two other windows will follow; the first informs you of the progress of the download and the second tells you that the transfer has been completed successfully. Confirm with “OK”.

3 You can now disconnect the

programming cable from the Magelis terminal and insert the communication cable XBTZ9680, used to link to the Twido via additional port 2. If the PLC is active, a “Connection in progress" message will appear on the panel shortly after the connection is made. This message disappears once the bus connection has been established successfully and the application is then displayed.


Schneider Electric

19

PLC

Introduction The PLC chapter describes how to initialize, parameterize and load the program to the

PLC in order to implement the functional description described above. The PLC program is created using Twidosoft.

Preconditions The following conditions must be met in order to carry out the steps described below:

• The Twidosoft Version 3.2 programming tool is installed on your PC • The “DP-ASI.twd“ Twidosoft project is available in the default directory that has been

set up (C:\Program Files\Schneider Electric\TwidoSoft\Applications) • The Twido PLC is switched on and supplied with power • The PLC and the PC are linked to one another via the PC <> Twido programming

cable (TSXPCX1031) via built-in port1.

Setting up communication

1 Once the Twido programming software has been launched, start by calling up the "DP-ASI.twd" PLC program by selecting: File -> Open. The "Applications” default directory in which the file should be located is displayed.

2 After the program has been loaded, communication with the PLC must be set up. Select : PLC -> Select a connection And select the port to be used; in this case, COM1.


Schneider Electric

20

Transferring a program

1 In order to transfer the program, the PLC and the PC must be connected to one another via the communication cable. Once the cable has been connected, select PLC-> Connect to create an online connection to the PLC so that you can download the program.

2 Before a program is downloaded to the PLC Twidosoft usually informs you that the program to be downloaded and the program in the PLC are different. In this case, use the button PC -> Controller to transfer the program to the PLC. If the PLC is in “run“ mode you are asked to stop the controller first before the download can be performed. In this case click OK. If there is a valid application on the PLC you are informed that this application will be replaced with the new application. In this case click OK again.

Assigning of Addresses to the AS-Interface modules

1 AS-Interface modules fresh from stock do not have a pre-set slave address. As it is not allowed to have more than one module with a certain address connected to one AS-Interface master, they need to be assigned a unique address. At this stage no AS-Interface module should be connected to the bus. To assign addresses to the modules select: Hardware -> Configure a module.

2 The dialog now shown, should list all configured modules connected to the Twido Expansion Bus – in this case only the AS-Interface master “TWD NOI 10M3”. Select this module and click OK.


Schneider Electric

21

3 The Configure Module dialog appears. As we are connected to the PLC the dialog has two Tabs: Configuration and Debug. Switch to the Debug tab. All configured AS-Interface modules are shown (addresses 01 .. 13). The indicators are red because the AS-Interface Master detects no module connected.

4 Now connect one non-

addressed TeSysU module to the AS-Interface bus. An “Unknown” module appears at address 00. The indicator is red because one module with the invalid address 00 is detected Now click on the “Unknown” module and drag it to first “ASI LUF C5” field left of address 01 and drop it there. After a few seconds the module is detected, the indicator turns to green and the “Unknown” module on address 00 disappears.

5 Repeat the procedure described above (4) for the • remaining 5 TeSysU

modules • 3 IP67 modules

ASI67FPM43E • 4 IP20 modules

ASI20MT4I3OSE when done the dialog shows all 13 modules detected and indicated as green. The AS-Interface master module is now able to operate the bus. End the dialog by clicking “OK”.

22

Starting the application

1 Now the application is ready to run. Select: PLC -> Run (RUN).

2 You have to confirm the start of the PLC by clicking OK.

Data exchange

Introduction The Magelis terminal is connected via Modbus to the Twido PLC. Magelis acts as

Modbus master, Twido as Modbus slave (slave address 1). For this connection the Remote Link 2 on Twido PLC is used. This chapter explains how the data is exchanged between the Magelis terminal and the Twido PLC via the Modbus connection as well as the assignment of communication data to the AS-Interface modules.

Performance characteristics of the complete system

Performance characteristics for example application

Introduction The data provided in this chapter is related to the system and its features as

described and specified in this document. The values shown vary widely depending on:

• the number of I/O points • the number of AS-Interface I/O modules • the number of instructions/operations (program size) • the memory utilization

Application reaction time for example application

The application reaction time is defined as the time needed to obtain an output reaction as a result from an input action. This means that the application reaction time is dependent on (simplified):

• the time needed to recognize the input signal • the time to transfer the input signal from the I/O module to the PLC memory • the time for the PLC application to calculate the dependent output value(s) • the time to transfer the output values from thePLC memory to the I/O

modules Furthermore one has to consider a worst case reaction time in order to ensure the given reaction time covers all cases. (see the tables below for worst cases(max))

The PLC scan time for example is 10 ms. The relevant application reaction time was measured as 33 ms (average: 25 ms, best case: 17 ms).

Worst-case Application Reaction for 13 and 31 AS-Interface modules

The Table below shows the differences between configurations of 13 respectively 31 AS-Interface modules. These differences vary between 3 and 8 ms. This shows that the dependence of the application reaction time on the number of configured AS-Interface modules is very low. The application reaction is almost stable for any number of AS-Interface modules.

This statement is valid only for AS-Interface on Twido PLCs and cannot be generalized for other Schneider Electric products.

Remark: How to get the relevant PLC scan time

Twidosoft displays the PLC scan time, together with other information, in the Controller Operations dialog. This dialog can be accessed after the PLC is started (see above) via PLC -> Check PLC. The Controller Operations dialog shows the longest, shortest and current PLC scan time.

How to use tables or diagrams

Read the current scan time. With that go to the relevant table or diagram above to obtain the expected application reaction time. See below for a more generalised method to estimate the application reaction time.

Performance characteristics for Twido with AS-Interface

Introduction The following sections discuss some notable facts of the AS-Interface bus system

when used in co-operation with Twido PLCs. Cable The length of an AS-Interface cable system is limited to 100 m. It can be extended

using repeaters to an overall length of 300 m (2 repeaters max.). Any branches off from the ‘main’ cable must be added to the cable length. AS-Interface modules which drive devices (e.g. TeSysU motor starters) or I/O-modules which require more than 20 mA load on their outputs need external auxiliary power via the ‘black cable’.

Number of modules

Dependent from the interface version of the module the Twido master module can operate the bus in two topologies: • There may be up to 31 modules with standard addressing connected to one

Twido AS-Interface master. The bus cycle is dependent on the number of connected modules and needs approximately 0.16ms per module – i.e. 5 ms for an AS-Interface cable with 31 modules.

• Using extended addressing, there may be up to 62 modules connected to one Twido AS-Interface master. The bus cycle is dependent on the number of connected modules and needs approximately 0.16ms per module – i.e. 10 ms for an AS-Interface cable with 31 modules addressed as A-Slaves and 31 modules addressed as B-slaves.

• Modules with standard addressing appear as A- and B-slaves simultaneously. Performance of Twido AS-Interface master

The master module is responsible for transferring the data from the connected AS-Interface modules to the PLC memory and vice versa. The time required for this is fixed and independent of the number of connected modules and is 8 ms. If the twido uses two AS-Interface master modules, the time needed is 18 ms.

Performance Rule of Thumb

To estimate the maximum application reaction time the following algorithm can be used: Application Reaction Time (ms) = 2 * PLC scan (ms) + 2 * No_Of_Modules * 0.16 ms + 10 ms

Caution

It may be that the Application Reaction Time calculated with the given algorithm leads to incorrect results. Under particular circumstances the Twido-AS-Interface-system could have longer application reaction times as expected!

Twidosoft displays the PLC scan time, together with other information, in the Controller Operations dialog. This dialog can be accessed after the PLC is started (see above) via PLC -> Check PLC. The Controller Operations dialog shows the longest, shortest and current PLC scan time.

How to use the Algorithm

Read the “current” scan time. With that and the quantity of AS-Interface modules use the formula above to calculate the expected application reaction time.
