MEsoftstart PC App  

This section describes how to install the MEsoftstart PC App on the user’s computer and how to use the interface to configure, 
monitor and control the soft starter. 

The MEsoftstart PC App is tested to run on the Windows 10 operating system. 

Two versions of PC Application software are available: for the Pro variants and the Core variants - the difference between the 
two is shown in the table below.  

 

Table 19: MEsoftstart PC App differences for Pro and Core variants 

MEsoftstart/I Pro variants 

MEsoftstart/I Core variants 

Configuration 

The MEsoftstart/I Pro variants are full featured soft starters 
that are highly configurable.  
The PC Application for the Pro variants are designed to make 
the complex configuration easy. 

The MEsoftstart/I Core variants are easy to use with 
configuration via potentiometers and switches.  
The PC Application for the Core variants allows the user to 
view the configuration (as set by the potentiometers and 
switches) and set limited configurable parameters  
(refer paragraph 5.2.1). 

Monitoring 

The PC Application for the Pro variants provides real-time 
monitoring (while the motor is idle, starting, running and 
stopping). 

The PC Application for the Core variants provides monitoring 
(while the motor is stopped or running but not while starting 
and stopping)  

Control 

The Modbus link (PC Application, PLC or SCADA) allows Start, Stop and Reset control 

Interface 

The MEsoftstart PC application for Pro variants can be used 

with Modbus RTU or Modbus TCP. 

- 

Modbus RTU interfaces on the RS485 RJ45 connector  

on J2 or J3 

- 

Modbus TCP interfaces on the RJ45 Ethernet port on J1 

The MEsoftstart PC application for Core variants is based on 

Modbus RTU and interfaces on the RS485 RJ45 connector on 
J1 or J2. 

Cable 

If the Modbus TCP interface is used, an Ethernet cable may 
be used to connect the PC with the soft starter. 

If Modbus RTU is used a special cable is needed that 
converts the RS485 on the soft starter to a USB interface on 
the laptop. 
It is recommended to use the cable that is supplied to 
ensure that the supported buffer size of the converter is 
adequate. 

Download the following version 

- 

MEsoftstart/I Pro

 PC Interface Application  

(supports RTU and TCP) 

- 

If using Modbus RTU, the 

Driver for Modbus Interface

 is 

required

 

- 

MEsoftstart/I Core

 PC Interface Application  

(supports only RTU) 

-
