Productivity Open P1AM Industrial Arduino Modbus TCP to C-More Micro EA3


We will now look at P1AM Arduino Modbus TCP communication to the C-More Micro EA3 HMI. This will be communicating the Ethernet Modbus TCP protocol. The P1AM will be the server (slave) and the EA3-T4CL the client (master).
P1AM Arduino Modbus TCP
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.
The P1AM Example from Automation Direct on GitHub will be used.

We will be using the C-More Micro EA3-T4CL HMI that is posted. Let’s get started. Continue Reading!
