6.2 Configuring the 3RW5 soft starter in the Modbus RTU system
Requirements
● Mounted 3RW5 Modbus RTU communication module
3RW50 soft starters must also be connected to the 3RW5 communication module.
The 3RW5 soft starter automatically detects the presence of the
3RW5 communication module when it is switched on.
● Modbus RTU system
– Master
– Slave (3RW5 Modbus RTU communication module)
● Configuration software of the controller, e.g. STEP 7
● Parameterization software, e.g.
– SIRIUS Soft Starter ES (TIA Portal) (Page 42) via local interface on the
– Modbus RTU master
● Depending on the control system, further hardware and software components may be
required for Modbus RTU. Additional information can be found on the Internet
