We will now look at p1am arduino modbus tcp communication to the C-More Micro EA3 HMI. This will be communicating ethernet modbus TCP protocol. The P1AM will be the server (slave) and the EA3-T4CL the client (master).
More information can be obtained on our website. This includes all of the links mentioned in this video.

There was a recent question on the Automation Direct Customer Forums that asked, "How do I connect an HMI C-more EA3-T4CL and
P1AM PLC?".
We will explain how to connect this to our P1AM-ETH Industrial Arduino Ethernet Shield.
