Corrected from:
PLC Designer V3.14
Response of the new version:
In the function block diagram editor, "Blocks with EN/ENO" can be inserted and marked as "MOVE". No exception occurs.
What happens?
The following exception occurs in the PLC Designer:
Index was outside the bounds of the array.
When does this behaviour occur?
The exception occurs if a "Block with EN/ENO" is inserted in the Function Block Diagram (FBD) and then marked as "MOVE".
The MOVE operator is an assignment. If the MOVE operator has an EN input, you can program a conditional assignment with it.
Which products are affected?
PLC Designer from V3.12
Short-term measures:
As an alternative, use the "MOVE" block from the "Other operators" category in the elements of the FBD editor.
Evaluation/recommendations:
If a "Block with EN/ENO" is marked with "MOVE" in the FBD editor, an exception occurs. The project can still be saved after the error has occurred. A remedy is described under 'Short-term measures'.
