Hello everyone,

I work on a ET-200SP and for the first time, I use OPC-UA.

I have 3 TCP port in my PLC and the default value of the TCP port is 4840 (in OPC-UA).

How can I find out which port this default value corresponds to ?

Thanks for your replies.

Best regards,

GW

Hi GW,

A TCP port is not a physical port on your device. The port number is used to uniquely identify multiple connections to the same IP address.

See https://en.wikipedia.org/wiki/Port_(computer_networking) for further details.

 Thanks for your respond.

Best regards,
