Technical Request: Multi-Network Access to the OPC UA Server of an S7-1500

I am using a Siemens S7-1500 PLC equipped with a CP 1542-SP1 communication module.
The goal is to make the OPC UA server integrated into the CPU accessible both through the CPU’s main Ethernet network and through the secondary network connected to the CP 1542-SP1.

In practice, I would like to add a second IP address (the one of the CP module) in the OPC UA server configuration so that OPC UA clients can connect via either network, depending on their location.

The technical question is therefore the following:

Is it possible to configure the OPC UA server integrated into an S7-1500 CPU so that it is simultaneously accessible via both network interfaces (CPU and CP 1542-SP1)?
If so, what are the exact steps to perform in TIA Portal to enable this dual-network access?

Hi, Hati,

Thank you for your quick reply. 

Would it work if we install a CP 1543-1 communication card?

Tks in advance
