?Corrected from:
PLC Designer V3.9
Response of the new version:
If the topmost variable in a global variable list is mapped to a hardware input, no warning will appear when compiling the PLC project.
What happens?
When compiling the PLC project, the following warning appears in the message window of the PLC Designer:
'Variable' is no valid assignment target
When does this behaviour occur?
If the topmost global variable in a global variable list is mapped to a hardware input, the above warning will appear when the PLC project is compiled.
Which products are affected?
PLC Designer from V3.0
Short-term measures:
Declare a global variable at the topmost position of the global variable list which need not be mapped to a hardware input.
Evaluation/recommendations:
The topmost global variable in a global variable list must not be assigned to a hardware input since this will lead to a warning during project compilation.
