44 • Fieldbus Controller 750-841
Hardware
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
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
ineffective because the program is no longer processed.
Note
With "GET_STOP_VALUE" (library "System.lib") WAGO-I/O-PRO CAA
provides a function which recognizes the last cycle prior to a program being
stopped. This gives you the ability to program the behavior of the controller’s
outputs before a STOP condition. With this feature, the controller outputs can
be switched to a safe state before the PFC stops.
3.1.2.7 Hardware Address (MAC-ID)
Each WAGO ETHERNET TCP/IP fieldbus controller is supplied 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’s side. The address has a fixed length of 6 Bytes (48 Bits) and
contains the address type, the manufacturer’s ID, and the serial number.
