Hi Dears,

I'm using Node-red-contrib-cip-ethernet-ip reading tags from a Compact Logix AB PLC, with the All Tags option. The tags are read correctly, however always with the message "Error communicating with the PLC: Error: TIMEOUT occurred while writing Reading Tag Group". Some suggestion?

Thanks,

Roberto

I have the same problem. For me it works fine until I unplug the PLC, then the same error occurs. If I deploy the current NodeRed project, error disappear even if the reason for deploy is just a tiny change like moving debug block around (I am using my PC to run NodeRed)
