Which products are affected?
ECS Application OPERATING SYSTEM <=V8.3
What happens?
The AIF_wControl system variable (AIF_IO_Management system block) can be used to send a command to the AIF module.
When does the problem occur?
The reaction described above occurs when using the AIF_wControl system variable.
Diagnostics options?
None
Short-term measures/recommendations?
Use code C2120 to send commands to the AIF module, e. g. using the L_ParWrite function block.
Evaluation:
The functional restriction occurs whenever the AIF_wControl system variable is used to send commands from a PLC program to the AIF module, e. g. EMF2175IB. The functional restriction is detected at the latest during commissioning.
