Sure Rob it was listed in the Overview section but I will be happy to help you with that. It can communicate with over 300 different protocols, G3 HMIs are among the most powerful HMI communication platforms available today. They can manage vendor‑specific applications and provide the ability to network‑enable existing equipment. Select the PLCs, drives, motion controllers or PID controllers that work best with your application, and you can control them all from this G3 HMI.
Well ok it has one 10/100Base‑T(X) Ethernet, two RS‑232 and one RS‑422/485 serial ports and support serial to Ethernet conversion. Additional Ethernet, RS‑422/485 and USB Host ports are also available on specific models. A maximum of up to five high‑speed serial ports are available. CANopen, serial ports, DeviceNet, and Profibus communication cards can be installed after purchase to further expand the G3’s connectivity.
Hope this helps
