When performing a Block Transfer Write and Read operations from analog cards on a A\B PLC 5, is it recommended to utilize the error (ER) bit for error handling or is this really not a concern. If ER isn't utilized, I'm wondering how one would know if the board stops responding to BTR/BTW's, aside from an obvious (possibly) process excursion.
The boards in this case are in the same rack as the processor. On one hand I think this is a moot point given that most of the time if a board fails (in my experience at least); the processor faults - I am puzzled by the ER bit in this sense.
Thanks
