MEsoftstart PC Interface
The MEsoftstart PC interface is available as a two-wire RS485 port plus ground Modbus RTU interface on all MEsoftstart/I models
(MEsoftstart/I00 – MEsoftstart/I04).
On Pro variants of MEsoftstart/I01 – MEsoftstart/I04, the MEsoftstart PC interface is also available on the Modbus TCP interface
(on the Ethernet port).
For the Modbus RTU it is recommended to use the dedicated RS485 to USB cable that is available with the MEsoftstart PC App.
This cable plugs in on the J2 or J3 RJ45 connectors on the soft starter (refer Figure 19) and connects to a USB port on the PC.
Note that drivers for the RS485 to USB converter may need to be installed. For the MEsoftstart dedicated cable, the drivers will
be provided with the cable. Refer par 7.1 for instructions to install the drivers and the application.
The soft starters may be daisy-chained on the RS485 line to enable the PC to configure them one after the other without having
to move the cable. To minimise reflections the RS485 lines need to be terminated with a 120Ω resistor at the far end.
Modbus TCP is available on the Pro variants' Ethernet RJ45 port on J1 and a standard Ethernet cable may be used between the
soft starter and the PC, SCADA or PLC as required.
