3.3 LED displays
The three LEDs on the front of the module inform you about its
operating state.
LED Power (green): Continuous light indicates that the PROFIBUS
is running and the CPU is in run mode. Slow
blinking indicates that the CPU
is in stop mode.
LED DP (green): A parameterization error on the
PROFIBUS has occurred.
LED CAN (yellow): CAN frames are being received
by the CAN bus.
3.4 DIP switches
The 8-switch DIP switch on the housing front is
used for setting the PROFIBUS address of the
device.
Any change to the switch
position is only applied
after the next time the
device is powered up!
The switches are counted from bottom to top.
