I have an SLC500 and I am doing some changes for a customer. We don't have enough I/O to properly recreate the hardware setup. Is there a way I can prevent the PLC from stopping when the hardware is half missing? Thanks a lot, Phil

You can turn off the slot enable bits for the missing cards, but the rack size must match the actual hardware.

You can also temporarily replace the I and O bits with unused groups of B bits for the missing slots to assist in the testing phase, just remember to change them back when done. Analog slots might not work this way, haven't tried that.
