Additional information
To open the data sheet for an I/O module, click in the "Configuration" window on
the corresponding I/O module and then click the [Data sheet] button. The data
sheet is then shown in a separate window.
All current data sheets are available on our website
Documentation.
8. Click [OK] to accept the node configuration and close the dialog window.
The addresses for the control system configuration are then recalculated and the
tree structure for the configuration is updated.
If required, you can also modify the authorization privileges for individual I/O
modules if they are to be accessed via fieldbus (MODBUS TCP/IP). Initially, write
access from the PLC is defined for each I/O module that is added. Proceed as
follows to change this setting:
9. Click the "PI Assignment" tab in the "Configuration" dialog.
10. Define for each module from where access to the module data is to be
carried out.
You can choose from the following settings in the column "PI Assignment" for
this:
• PLC, PLC (standard setting)
• fieldbus 1
• fieldbus 2
After completing these settings you can begin the IEC-61131-3 programming.
An "EA-config.xml" configuration file is automatically generated and stored in the
fieldbus controller, when you transfer the project (Menu project >
transfer/transfer all) and download it in the fieldbus controller.
Set "MODBUS TCP/UDP, fieldbus1", when directly writing to a hardware
address via MODBUS!
Set "MODBUS TCP/UDP, fieldbus 1" if you wish to write directly to a hardware
address via MODBUS. Otherwise the modules will be allocated to the PLC,
making writing from a different location impossible.
