Using TSW212 to communicate between two seperate networks

Hey, I have a TSW212 switch and was told by our IT to use it for my project.

My project involves getting our machine with an IP address of 10.10.99.103 to communicate with our OT network (172.16.1.XXX) that has a Scada system running on it.

In the past I would use a NAT device, but my IT suggested I use the TSW212.

How do I get my Scada system (172.16.1.20) to communicate with my PLC on 10.10.99.103?

Do I use static routing?

below is a rough sketch of the setup:

Greetings,

On the TSW212, navigate to Network → VLAN and create a new VLAN. Assign the port connected to the PLC as untagged for this VLAN.

Next, go to Network → Interfaces and create a new interface similar to the one shown in the screenshot. You may use a different IP address if needed, but ensure it is within the same subnet as the PLC.

After that, configure the PLC’s default gateway to be the IP address assigned to the new TSW212 interface (10.10.99.1 in this example).

Finally, on the main router/gateway, add the following static route:

  • Destination: 10.10.99.0 / 255.255.255.0
  • Gateway: 172.16.1.135

Please let me know if this works for you.

Best Regards,
Justinas
