Corrected from:
PLC Designer V3.12
Response of the new version:
When moving or renaming I/O 1000 modules in a PLC project, the selected mapping remains unchanged.
What happens?
- When the PLC project is compiled, the compiler displays the following error message:
Already existing variable xyz is mapped on several inputs!
- Variables mapped on inputs of I/O1000 modules have wrong value.
- Outputs of I/O1000 modules output wrong value.
When does this behaviour occur?
If an I/O1000 module that is connected to an EPM-S130 EtherCAT bus coupler is moved or renamed in the PLC project, the mapping may change such that the inputs and outputs connected to the bus coupler are no longer mapped on the variables on which they were mapped before the module was moved/renamed.
Which products are affected?
PLC Designer V3.2 and higher
Short-term measures/recommendations:
After moving or renaming I/O1000 modules, check on the "EtherCAT I/O Mapping" tab of the EPM-S130 EtherCAT bus coupler if the mapping on the variables is still correct.
If necessary, correct the mapping manually.
Evaluation:
Moving or renaming an I/O1000 module in the PLC project may lead to faulty mapping. I.e. the variables in the PLC project are not assigned to the right I/O module inputs and outputs. In general, this kind of changes are only carried out in the PLC project during the configuration or commissioning phase.
