Allen Bradley 1761-NET-ENI over the internet

Does anyone know how I can use RSLogix 500 to connect to a SLC 5/03 over the internet with a 1761-NET-ENI module?

 

[Ken Roach]

The 1761-NET-ENI uses ordinary TCP/IP so you can connect to it over any connection that uses TCP/IP.... Ethernet, DSL, DOCSIS, PPP... and the Internet.

Do not connect the 1761-NET-ENI (or any other automation device, for that matter) directly to an Internet connection and give it an Internet address. Use a VPN circuit, whether via enterprise servers or a simple home router.

So, what port does it use? Or is it configurable?

Would I just forward one port through to the outside world?

 

[Ken Roach]

It uses TCP Port 44818.

I very strongly recommend against opening even this port to the Internet. A VPN is the only method that any commercial enterprise uses to connect to a remote site over the public Internet.
