How can I determine if the RJ45 port on my Modicon M340 CPU is a Modbus or Modbus TCP/IP port ?

Published date: 24 September 2018

There are two options as listed below:
1. The port has a label printed above or below it, which will indicate either Modbus or Ethernet.
2. The port has a color coded triangle indication on the right side of it. A black triangle indicates a serial or Modbus port and a green triangle indicates an Ethernet port.
