SOFT STARTERS
Soft starter communication options
AuCom medium voltage soft starters can connect easily to Modbus, Profibus or DeviceNet communication
networks, using simple add-on communication interfaces.
All communication interfaces allow you to:
control the soft starter
monitor the starter's operational or trip status
monitor the starter's current level and motor temperature (using the motor thermal model)
Some protocols also allow you to read and write soft starter parameters.
For installations with no existing network, AuCom also offers WinMaster, a PC-based software program which
allows control, monitoring and parameter management via an RS485 or USB connection.
Modbus Interface
MVS and MVX soft starters can operate as slaves on a Modbus network via a Modbus Interface.

Modbus interface
RS485 connection onto a Modbus RTU
network
The Modbus Interface is powered by the soft starter.
Each soft starter requires a separate Modbus Interface.
A Modbus RTU network can support up to 31 Modbus Interfaces as slaves.
The interface is configured using 8-way DIP switches. For more information on using the Modbus Interface,
refer to the Modbus Interface instructions.
Profibus Interface

Profibus DP (3-wire network cable)
The Profibus Interface requires an external 24 VDC supply.
Each soft starter requires a separate Profibus Interface.
A Profibus DP network can support up to 31 Profibus Interfaces as slaves.
The Profibus node address is selected using two rotary switches on the interface. The interface
automatically detects the data rate.
The GSD installation file is available from the AuCom website. For more information on using the Profibus
Interface, refer to the Profibus Interface instructions.
Tested and certified by Profibus.
