Installed node-red-contrib-cip-ehternet-ip but getting error

I am trying to connect with allen bradley PLCs but unable to connect with my PLCs. I have configured everything but still getting error "Error connecting to PLC: Error: TIMEOUT occurred while reading Controller Props". Could anyone tell me might be the problem?

I've moved your post to the #general topic as it is not a feature request for the core of Node-RED.
