Hello I am new to Node-red , have background in PLCs . So I am trying to connect Micro820 to node-red using this node ( trying different nodes), I am using windows. After reading couple of the issues here , I don't know if the node is still not compatible with Micro820 PLCs I keep getting this error " Error: <SCAN_GROUP> TIMEOUT occurred while writing Reading Tag Group " At first I had this error Error: TIMEOUT occurred while reading Controller Props." But I followed the suggestion in this thread , and I was able to connect to the controller https://github.com/st-one-io/node-red-contrib-cip-ethernet-ip/issues/10 So it might be the timeout value ( I tried different values), or simply the node isn't compatible with Micro820 PLCs. Thank you all for the help
