Connection to an Inverter

This section explains master communications with an inverter via RS-485 MEMOBUS.

8.5.1

System Configuration

Connect the inverter (VS-616G5) to the RS-485 port of the 217IF Module to control the
Inverter. This enables 1:N communications, thereby enabling multi-drop connections and
control of multiple Inverters.

The engineering environment is provided by connecting the MPE720 Programming Device
to the RS-232C port of the 217IF.
