Attention
If outputs are set when switching over the operating mode switch from RUN
to STOP, they remain set! Switching off the software side i.e. by initiators,
are ineffective, because the program is no longer processed.
Note
With
"GET_STOP_VALUE" (library "System.lib") WAGO-I/O-
PRO

provides a function which serves to recognize the last cycle prior to a pro-
gram stop giving the user the possibility to program the behavior of the Con-
troller in case of a STOP. With the aid of this function the Controller outputs
can be switched to a safe condition.
3.2.2.7 Hardware Address (MAC ID)
The DIP switch is used both for parametrizing (setting the baud rate) of the
fieldbus controller and for setting the MAC ID.
The MAC-ID (node address) is set with the DIP switches 1 to 6 by 'sliding' the
desired DIP switch to 'ON'.
The binary significance of the individual DIP switches increases according to
the switch number. DIP switch 1 being the lowest bit with the value 2
0
and
switch 6 the highest bit with the value 2
5
. Therefore the MAC ID 1 is set with
DIP1 = ON, the MAC ID 8 with DIP4 = ON, etc.
For the DeviceNet fieldbus nodes the node address can be set within the range
from 0 to 63.

The configuration is only read during the power up sequence. Changing the
switch position during operation does not change the configuration of the
buscoupler. Turn off and on the power supply for the fieldbus controller to ac-
cept the DIP switch change.
The default setting is MAC ID 1.
