I would use Modbus TCP but you will also need a P1AM-ETH.
does automation direct sell the modbus TCP?
Modbus TCP is a communications protocol that is over Ethernet that is why you would need the P1AM-ETH. If i recall correctly you will need to set up the P1AM as a modbus server and the C-more as the modbus client.
The following link will show a sample EA9 project that works with the P1AM-100 using Modbus TCP. A EA3-T4CL will also work.
https://github.com/AutomationDirect/P1AM-Examples/tree/master/P1AM-100_ModbusTCP_KitchenSink
Modbus is a master (client) / slave (server) protocol that can be done via serial or Ethernet.
This video is a great introduction to the Modbus TCP protocol:

I hope this helps you out.

thats nice to know that it is possible to connect the P1AM-100 to a EA9 but can it connect to a EA3?
see page 4 the EA3 that you specified does support modbus TCP.
https://cdn.automationdirect.com/static/specs/ea3t4cl.pdf
The EA3-T4CL has a built-in Ethernet port that supports Modbus TCP.
Page 4 does specify Modbus TCP.
Here are a couple of posts that also show Modbus TCP using the EA3-T4CL and the Do-More Designer Simulator.

Hi Bob2
I have not done it with the P1AM-100 but Modbus TCP communication should work the same as the EA9 and EA3.
I will be doing a post on the P1AM to C-More in the new year. (EA3 and EA9)
I do not know your exact application, but have you looked at the headless c-more?

Android, IoS and windows apps are free of charge to connect and control remotely.

Decided to try this connection....
Worked as expected.
A head start on the post that I will be doing on the P1AM.
