Typically the PLC cycle consists of Input scan -> Program Run -> Update outputs.
In the attached picture (Carel 1tool software) I have 4 pages which contain plc logic programs in specific order.
The PLC is running first the Process 1, then the second page Process 2, then Process 3 and lastly it updates the outputs.
The problem is that it doesn't matter if the status of the outputs should be updated according to the logic in Process 1 or Process 2 it will not change since the page Process 3 is last one in the order and the outputs will be always updated according to the logic in this page.
What could be the solution for this?
