Hello @GPV,
Apologies for the delayed response.
There’s no such feature on RUT956. You can try to implement your own workaround using scripts and Custom Modbus Registers. The idea is that you would create a script to get Modbus data from UMG604 registers and store it in a custom Modbus registers block (a separate file). You can utilize crontabs to execute your script (send modbus requests to UMG604) periodically. Then, you can read those custom registers from RUT956 via Modbus RTU.
For Scripting, refer here.
For Crontabs, refer here.
For Modbus CLI commands, refer here.

Kind Regards,
