The interface for supervising a Modbus over 485 system (RTU protocol) is designed for mounting in an electrical cabinet, on a DIN rail (2 modules). The supervisory system to which the interface is connected must have a ModBus RTU(RS-485) protocol. The communication parameters are given in the table in the "programming instructions" section. The interface allows a third-party supervisory system to modify and read the parameters of the REG system, which is seen as a slave device. All connections are made via removable terminals.

The module is equipped with LEDs for status indication:

• PWR = power supply
• COMM = communication with the REG system
• ALARM = not used
• BUS = communication via ModBus protocol with third-party supervision system

A 16-position rotary switch is provided for selecting the module address and communication parameters
