Note
Length of the device name
The length of the device name is limited to 20 characters when the name is entered via the 
3RW5 HMI High Feature. If a longer device name has already been set (e.g. via SIRIUS Soft Starter 
ES (TIA Portal)), the 3RW5 HMI High Feature can only display and change the rst 20 characters.
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.
Menu: "Parameter > Communication module > PROFINET / PROFINET HF > MAC address"
Transferring or setting the device name
If you transfer the device name online or set it directly on the 3RW5 soft starter, the device name 
is stored retentively in the 3RW5 communication module.
Note
Restarting the communication interface
Any change of the device name via SIRIUS Soft Starter ES (TIA Portal) requires a restart of the 
communication interface.
A new start interrupts all PROFINET links and reestablishes them afterward.
6.2.1.4 IP parameters
All PROFINET devices are capable of the TCP/IP protocol and therefore require an IP address to 
operate on the PROFINET.
IP parameters
• IP address
• Subnet mask
• Router address
Temporary IP parameters
During startup, the IO controller issues the IP parameters based on the device name and assigns 
these to the IO device. The IP parameters assigned by the IO controller are stored non-retentively 
in the 3RW5 communication module and are deleted again when the supply voltage (control 
supply voltage) is switched o.
