I assume that you are talking about the node-red-open-protocol node, right? If yes, you have to check in the ToolsTalk if the OpenProtocol is enabled, if not then you can enabled it at any of the interfaces. There should be no problem on enabling it in the any of those 2 Ethernet ports.

Hi Mr Tiago, i have a doubt, the connection is good,when I'm trying to read any parameter, appears an error, i need to map the variables in the powertools software,or any configuration its necesary ?
