Configuring
6.1 Configuring the 3RW5 Soft Starter in the Modbus TCP system.
Requirements
● Mounted 3RW5 Modbus TCP 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 TCP system
– Client
– Server (3RW5 Modbus TCP 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 TCP client
● Depending on the control, additional communication components may be necessary for
Modbus TCP. Additional information can be found on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/102020340).
● Fundamental knowledge in working with Modbus TCP, e.g. for IP parameters (Page 77)
