I have a system that I am trying (desperately and blindly) to get running with 3 Melsec FX3u PLC's and a GT1575 Touch screen. I have mounted 3 GT15-RS4-9S/TE comms cards in slot I/F1 but cannot make them talk with the PLC. Touch Screen diagnostics acknowledge the cards and the comms drivers but also output the fault message "Optional Memory Board is not attached Ch. No. X is disable" Note that X is one of the channel numbers (2,3 or 4) depending on which channel is being diagnosed.

Has anyone had any experience with this set up that can help?
