One of my customers has stated the following as part of a technical review of an Allen-Bradley PLC-5/40E system design:
"Smart card (block transfer required) in remote rack. This requires Block Transfer queue checks in program."
I have placed cards requiring block transfers in remote racks before and AFAIK this has not created a problem. I have seen the block transfer queue status bits in the S file but I have not implemented any use of them in any applications to date. Nor have any of my colleagues.
Has anyone had a problem with block transfers to remote racks? Could anyone point me to a document that describes what is being asked for?
