Configuration

General Information The configuration of decentralized systems connected by network is done in two steps:

The CPU has to be informed about which Communication Modules are assigned to it (internal and/or external Communication Modules).

The Communication Modules have to be informed about which peripheral devices are connected to them.

How to do this, it is discribed on the following pages.

Starting the Programming Software 1. Start the AC500 Control Builder programming software.

2. Select File > New to create a new project.

3. In the appearing window select the desired CPU. In our example, select PM581 V1.2.

NOTICE

Only CPUs from version V1.2 or higher can be DeviceNet masters!

4. In the appearing window click on OK.


A window will open where you can select the POU name, type and language.

5. Keep the settings PLC_PRG and Program for the name and the type. Select ST for the language.

6. Click on OK.

The ST editor is opened.

7. Select the menu item File > Save as to save the project under a specific name.


8. Select the desired directory and enter the project name (in our example: Test2).

9. Complete your input with Save.

Specifying the Hardware Configuration The software has to be informed about the hardware configuration, i.e. the hardware configuration has to be specified in the software.

1. Click on .

2. Double click the object PLC Configuration.

3. If the AC500 folder in the PLC configuration tree is closed, click on the symbol.


4. First enter the I/O devices connected directly to the I/O bus of the CPU: In the configuration tree, click on I/O-Bus[FIX] and press the right mouse button.

5. Select Append Subelement > DC532 and click to append the element.

The Communication Module is appended to the tree.

6. Repeat this procedure to append the analog module AX522.

Now append the DeviceNet Communication Module:

7. In the configuration tree, click on Couplers[FIX] and press the right mouse button.

8. Select Append Subelement > CM575 and click to append the element.


The Communication Module is appended to the tree.

Logo und version information


S500 Module Selection S500-I/O-Modules for configuration:

Here you can select a module, to insert or append to the configuration (by mouse click on a module).

Selected Module: Here the selected module is displayed.

You can add the selected module to the FBP-DC505-cluster by using the configuration control buttons (see Configuration Controls).

Protocol Display and EDS File Specific Command Buttons

Fieldbus Protocol: Fieldbus protocol selection.


Protocol I/O-Amount-Info: Amount of protocol specific digital und analogue Input/Output bytes. The line Max shows the maximum of I/O-Bytes per S500-FBP-E/A-Station. The line Used shows the actual used number of I/O-Bytes. An analogue I/O-value needs an amount of 2 Bytes (lowbyte and highbyte of one analogue value). The EDS configurator checks automatically, that the maximum will not be exceeded during configuration of the station. If maximum will be exceeded, an error message will be displayed.

I/O-Mapping-List: Independend of the physical arrangement of the I/O modules in DC505-Cluster, the DeviceNet-Protocol transmits first all digital I/O-Bytes, then all analogue I/O-Bytes. The FBP additionally transmits 16 diagnosis bytes after the last input byte. To make it easier to give to the I/O bytes symbolic variable names in SYCON.net, the I/O mapping list shows, which I/O byte belongs to what module. Use this list when working with the tool SYCON.net.

Command Buttons:

New Project: Open a new project

Load Existing Project: Open an existing project

Save Actual Project: Save the actual project

Create EDS and Save: Create and save an EDS file

Export EDS to SYCON.net: Export the created EDS file to specific SYCON.net directory

5. Use the I/O mapping list (EDS configurator) to see how the input bytes and output bytes are assigned to the S500 modules.


TIP

For the planning of your plant we recommend to use symbolic names according to your plant.

In this example, there were used module specific names to make it easier to understand the I/O mapping.

If you have given to the input bytes their symbolic names, now do the same with the output bytes:

6. In the netConnect window click on the symbol in front of the entry S500-DC505+… to open this branch of the tree.

Two folders for Poll_Input and Poll_Output are displayed.

7. Click on Poll_output.

8. In the row Name of variable click on the corresponding entry to give to the output bytes their symbolic names.

9. Use the I/O mapping list (EDS configurator) to see how the input bytes and output bytes are assigned to the S500 modules.

After completion of the variables configuration, the fieldbus configuration is finished.

10. Store the project via File > Safe.

If you change now to AC500 Control Builder (CoDeSys), you can see the variables under Resources > Global Variables > Slot 1 (Communication Module slot) > Slot1_Slave4<R>.
