Hardware Address (Mac-Id); Operating System - WAGO 750-341 Manual

3.1.2.6

Hardware address (MAC-ID)

Each WAGO ETHERNET fieldbus coupler is provided from the factory with
a unique and internationally unambiguous physical ETHERNET address, also
referred to as MAC-ID (Media Access Control Identity). This address is to be
found on the rear of the coupler and on an adhesive tear-off label on the side
of the coupler. The address has a fixed length of 6 Bytes (48 Bit) and contains
the address type, the manufacturer's ID, and the serial number.

3.1.3 Operating system

Following is the configuration of the master activation and the electrical
installation of the fieldbus station to start up the system.
After switching on the supply voltage, the coupler determines the I/O modules
and the present configuration.
In the event of a fault, the coupler changes to the "Stop" condition. The "I/O"
LED flashes red. After a fault free start up, the coupler changes to the
"Fieldbus start" status and the "I/O" LED lights up green.
