Remote support device for operational networks

[BKNUTTING]

Hello all,

I am missing something obvious. Spent a couple of hours trying to find a device so I can remotely support PLC's at multiple locations (think EWON or TOSIBOX). Should be simple but the caveat is that there are 3 different subnets for each location. I have been unable to find a gateway with routing abilities. I can stand up a router and program the tables but it seems that there should be a device that offers the ability to remote into from anywhere and get to one of three PLC's connected to this device without having an isolated router. Appreciate any guidance.

In the Allen Bradley world or anything for that matter, there are other brands of things... Like Phoenix and Siemens... I use a NATR device. 1783-NATR is the part number for Allen Bradley. Or something like a FL MGUARD 1102 from Phoenix Contact. Basically you assign IP address in the company side of that NAT to the PLC address.

For example there is a fixed IP assignment of 10.10.1.23 on the company side, then this NATR will translate that to 192.168.1.23 for example. So then it's as simple as VPN to the company network. Setting up your software to hit the ip address of 10.10.1.23 and your online with your PLC. Is this what you are looking for?

There are many of these devices like chris mentioned also supporting things like e-mail for alarming etc. but i would also look at the security like two-factor authentication.

The EWON system should work fine, it doesnt care what subnet it is on, as long as it can reach the Internet. From there the cloud system handles routing.
