Hello,
We have an application with the following hardware:
1 X20EM0611 CPU and 2 Power Panel T80 HMIs, connected via a switch to the CPU’s Ethernet port.
Is it possible to change the network settings (IP, subnet, gateway, etc.) and configure the reference web server (i.e., the CPU) using a function block from the CPU?
Thank you.
Hello Martin,
These can be configured via the OPC UA server of the T80 by using the OPC UA client function blocks in the PLC program.
Automation Help: T80 OPC UA server
You can check this example project where this is implemented:
br-automation-community/mappPanel: This is a sample for communication from a B&R PLC to a T-Panel over OPC UA.
Thank you! 
I will try
