Hardware Address (Mac-Id) - WAGO -I/O-SYSTEM 750 User's Installation And Configuration

An operating mode is internally changed at the end of a PLC cycle.
Attention
If outputs are set when switching from RUN to STOP mode, they remain set!
Switching off the outputs on the software side i.e. by the initiators are inef-
fective because the program is no longer processed.
Note
With "GET_STOP_VALUE" (library "System.lib") WAGO-I/O-PRO 32 pro-
vides a function which recognizes the last cycle prior to a program stop giv-
ing the user the possibility to program the behavior of the controller in case of
a STOP. With the aid of this function the controller outputs can be switched
to a safe condition.

Hardware address (MAC-ID)

Each WAGO ETHERNET TCP/IP fieldbus controller 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 is
located on the rear of the controller and on a self-adhesive tear-off label on the
controller side. The address has a fixed length of 6 Bytes (48 Bit) and contains
the address type, the manufacturer's ID, and the serial number.
