Corrected from: PLC Designer V3.12
Response of the new version:
In the device tree, I/O modules attached to the EtherCAT bus coupler cannot be deactivated individually. You can only deactivate the EtherCAT bus coupler EPM-S130 including all attached I/O modules. In this way, the function restriction can no longer occur.
What happens?
The EtherCAT master does not change to "Safe-operational" or "Operational".
The EtherCAT nodes indicate a red triangle symbol in the PLC Designer. The EtherCAT slaves report a bus error.
The following error is indicated in the 'EtherCAT Log messages':
EtherCAT_Master: Slave signals Error. AL state: PRE OPERATIONAL, AL state code: Invalid Input\Output Configuration
When does this behaviour occur?
I/O modules physically connected to the EtherCAT bus coupler EPM-S130 and deactivated in the device tree of the PLC Designer lead to the response described before.
Which products are affected?
PLC Designer V3.2 and higher
EPM-S130 (I/O 1000 EtherCAT bus coupler)
Possible diagnostics?
Check if the I/O modules are indicated as deactivated (in grey letters) in the device tree of the PLC Designer.
Short-term measures/recommendations:
Delete physically not existing I/O modules from the device tree of the PLC Designer instead of deactivating them.
Evaluation:
When inserting I/O modules into the PLC project, the modules are automatically active. They can be deactivated later via the context menu of the module. In this case, the EtherCAT master reports a configuration error immediately after downloading the PLC project.
