To connect and communicate to an Ethernet device like an Acromag Ethernet module, you have three potential connection scenarios:
- Direct connect your Ethernet device to your computer - Easiest but the most restrictive, as it dominates the use of your Ethernet port and may temporarily take your computer off-line from the internet.
- Network connect your Ethernet device to your LAN (Local Area Network) - A little more complicated and does not incude remote access from another network.
- Remotely connect to your Ethernet device over the internet - This requires the second scenario, but adds Port Forwarding, requires a static public IP address, and potentially adds the services of a VPN (Virtual Private Network).
This paper gives detailed information and examples on how to make these connections.
Ethernet I/O Modules
Analog I/O Ethernet Modules input/output modules perform A/D or D/A conversion to interface sensors, instruments, and actuators to a Modbus TCP/IP, Ethernet/IP, or Profinet control network.

Digital I/O Ethernet modules interface on/off, hi/lo, or open/close discrete logic devices and relays to a Modbus TCP/IP, Ethernet/IP, or Profinet control network.
