Concept 2.5 984 Ladder Question

I am writing some 984 ladder in Concept 2.5 and I would like to write to RIO discrete inputs. Can I do it? AB SLC will allow you to write to %I.
 
Hi ControlsGeek, Maybe what you really want is to exercise the ladder logic by simulating inputs (writing inputs per se has no other conceivable purpose). Construct in your ladder logic a BLKM that moves input bits into 4xxxx registers, then force the bits in the 4xxxx registers, then use those bits in your logic instead of the original inputs.

Modicon 984 uses 1xxxx addresses for discrete inputs. use the traffic cop function to map the remote I/O modules in your data table.
