I am using an OPTO-22 R1 controller with a Parker ACR9040 servo controller, and am having some trouble with the Ethernet communication between them, specifically checking a bit in the ACR to monitor "health" while the OPTO-22 program is running. Does anyone have any direct experience that they can share. I am using port 5002 on the ACR and most communication from OPTO-22 to ACR is great. The problem lies in querying the ACR about bit status.
Thanks for any and all help!
