GPI writes tot a 90-70 PLC
Our customer has a Bailey INFI 90 GPI 04 usng Modbus RTU serial to wite and read to a GEFANUC 90-70 PLC via a IC697CMM711. The reads and analog writes seems to seem to work but the discrete writes do not. ABB Service from Calgary came in and did an update recently and it has not worked properly since. I have been asked to review the application to help determine what is wrong. In a Bailey INFI 90 GPI 04 what the correct offsets for DIP’s with respect to %Qxxxx in the 90-70 PLC? The current offset seems to be PLC %Q value + 1025. The Translation settting is currently NONE. Should the Translation be set to GE CMM to work properly?

Sorry Ed, I do not know. INFI 90/Serial comms is way out of my league. Lets hope someone else here on AKS can assist.
