I am encountering an error while trying to access the TM_Status_Connected variable on my Omron NX1P2-9024DT PLC using EtherNet/IP protocol through Node-RED. Below are the details of the error and my setup:
Error Message:
Error communicating with the PLC: {"generalStatusCode":8,"extendedStatus":[],"ext":[{"func":"getControllerTags","instanceID":0,"program":null,"cipReq":{"type":"Buffer","data":[85,3,32,107,37,0,0,0,2,0,1,0,2,0]}}]}
Setup:
PLC Model: Omron NX1P2-9024DT Protocol: EtherNet/IP Node-RED Configuration: Using node-red-contrib-cip-st-ethernet-ip@v2.0.2 node IP Address and Port: Confirmed to be correct and matching the PLC settings Network Configuration: PLC and computer are on the same subnet Steps Taken:
Verified IP address and port settings. Confirmed the TM_Status_Connected variable address in the PLC. Checked network settings, including subnet mask and gateway. Ensured proper permissions for accessing the variable. Screenshots: !PLC Configuration !Node-RED Configuration !Error Message
Question: What could be causing this error, and how can I resolve it? Any insights or suggestions would be greatly appreciated.
