I am new to Opto 22 PAC software development (liked the flow of it, makes it easy to understand actual process) and on this forum.
We are using SNAP-PAC-R1 controller and PAC control professional version R9.6e.
I am currently facing following issue:
I can see that strategy and chart is running but logic is not getting executed (as if chart is suspended) after certain point (I have set flags at every step of the logic to track where the logic stops executing).
Now, this problem occurs only in certain case (Lets say case A). In other case (Case B) logic seems to perform correctly (Both strategy and chart running with logic getting executed).
I am not able to narrow down where the problem could be, any pointers in the direction of trouble shooting will be appreciated.
In case A and B both, it is closing a valve using serial communication RS232 (and some additional tasks), in case B valve is already closed but in case A valve which is open actually performs the closing operation. Action of closing valve is performed in another chart.
