HI,
I am working at a program where the M241 is the main brain of the control system, but we have a little M221 off the side doing its own thing. I need communication between these two. The M241 needs to know the status of the I/O points on the M221. Do I understand it right that the %IWM and %QWM or the status words for the I/O? I would appreciate a little direction on the best way to do this. I have done it between M221's before, but wasn't sure the best way to do it from the M241 side. Thankyou.
