Corrected from:
Cabinet Controller c520 V1.11
Cabinet Controller c550 V1.11
Response of the new version:
The process image data of the EPM-S310 IO1000 modules on the backplane bus of the controller are updated independently of the use of the communication modules (EtherCAT slave or Profinet slave).
What happens?
The process image data of the IO1000 modules EPM-S310 on the backplane bus of the controller do not change.
When does the behaviour occur?
Fast output modules (EPM-S310) are connected to the backplane bus of the c5xx controller.
In addition, an EtherCAT slave or Profinet slave communication module is plugged into the option slot of the c5xx.
If the sum of the input/output data on the backplane bus reaches 64 bytes, the described behaviour occurs.
Which products are affected?
Cabinet Controller c520 from V1.0
Cabinet Controller c550 from V1.0
Evaluation / recommendations/short-term measures:
The EPM-S310 output modules can be connected to an EPM-S131 EtherCAT bus coupler. In this case the described behaviour does not occur.
