I've read this article: https://wiki.teltonika-networks.com/view/RUT955_Monitoring_via_Modbus,
that explains how to read the RUT955 router internal registers with modbus read from a Linux terminal.
Is it possible to use the modbus read (or another utility) from a Linux terminal to request the router's slave device's registers?
The connection scheme is the following:
┌────┐ TCP ┌─────┐ RS485 ┌─────┐
│ PC │ <-------> │ RUT │ <---------> │ PLC │
└────┘ └─────┘ Modbus └─────┘
I saw there's an option for Modbus Gateway in the Services -> RS485 section.
So this means the router will be an intermediary node between the PLC and the Linux PC?
And the pymodbus should be installed on the Linux side, right?
