How to create a Modbus Driver in Arduino IDE
I am trying to use EA3 S3ML HMI with a P1AM-100 ProOpen CPU and P1-08TRS relay or output module. I would like the HMI to use the CPU to control the outputs, allow the user to input times between on and off cycles and use a counter to keep track of the amount of current cycles. I am a little confused about connecting the HMI and P1AM-100 perform the above listed functions. Any help would be much appreciated.
We have an example project that contains .ino (P1AM-100) and .mgp (cmicro) files that will get you familiar with getting connected.

Thank you for your quick response. The issue I am having is how to take, for instance an on and off button and link the PLC to the EA3 SM3L HMI, through the Arduino code?
Hi @Night rider (Customer)
The following post will show you how to connect the EA3 to the P1AM with Modbus TCP.

This will include your digital IO and registers.
The entire P1AM series can be found here:

I hope this helps you out.
