Hi, I am working on connecting an AutomationDirect P1-540 PLC to Factory I/O.

I am able to connect to the outputs (where the Offset is 0) but I can’t connect to the inputs (Offset is 10000). The issue is that 100000 is too long of a number to fit in the “Offset” box. It limits me to six characters. This seems like a bug to me. Is there a solution to this issue?
