Static Ip Parameters; Mac Address - Siemens SIRIUS 3RW5 Equipment Manual

6.3.1.3 IP parameters
All Modbus TCP devices are capable of using the TCP/IP protocol. Before the
3RW5 soft starter can be addressed as a server by a client, the
3RW5 communication module must have IP parameters. The IP parameters of the
3RW5 communication module must match the IP parameters in the Modbus application, so
that the Modbus TCP client can communicate.
IP parameters
● IP address
● Subnet mask
● Router address
The factory settings (default) of the IP parameters are listed in chapter Modbus TCP
communication parameters (Page 176).

Static IP parameters

The IP parameters set on the 3RW5 soft starter are stored retentively in the
3RW5 communication module. The IP parameters of the 3RW5 communication module must
match the IP parameters in the Modbus application.
Note
Restarting the communication interface
Any change in the IP parameters via SIRIUS Soft Starter ES (TIA Portal) requires a restart of
the communication interface.
Restarting interrupts the Modbus TCP connections. Reestablish the Modbus TCP
connections.

MAC address

Via the MAC address, the 3RW5 communication module can be accessed via LAN. You can
read the MAC address on the front of the 3RW5 communication module or display it on the
3RW5 HMI High Feature.
