8.5.2 LEDs
PBM100 has 4 LEDs which are connected as described below:
8.5.3 PROFIBUS DP Communication
Specification of the PB master input data
In the following, the input data that the PBM transfers to the master is specified:
LED Colour Description
PWR green ON: Module working in normal mode = fully initialised and
without any fault.
CAN green OFF: No communication or CAN BUS error
Blinking with 2 Hz: Errors (optional, if a CAN warning is
detectable)
ON: CAN is ready.
PB green OFF: no communication via PROFIBUS DP
ON: communication without error via PROFIBUS DP
ERR red OFF: no errors
ON: PBM100 Initialisation incomplete or not yet success-
fully completed or CAN message missing for more than 3 s.
