Remedial measures for fieldbus errors
Fieldbus errors The fieldbus status LEDs indicate the operational state of the fieldbus. The
functions of the Profibus are indicated by the “I/O-RUN” and “BF” LEDs in
the BK3000 and BK3100, and by the “I/O-RUN”, “BF” and “DIA” LEDs in
the BK3010, BK3110 and BK3500.
Fieldbus errors in the BK3000/BK3100
I/O-RUN BF Meaning Remedy
on off Operating state: RUN
Inputs are read and outputs are set.
Everything is operating correctly
on on 1. Bus activity, but slave is not yet
parameterised
2. Bus error in which the outputs
a.) become 0
b.) remain unchanged
- Start master
- Check bus cable
- Check parameters
(-> Diagnostics data)
- Check configuration
(-> Diagnostics data)
off off 1. Terminal bus cycles synchronised
DP-watchdog switched off, no exchange
of data
2. Reaction to Clear_Data
Master in Clear_Mode, reaction of the
terminal bus is stopped PLC is in STOP mode
off on 1. No bus activity
2. Bus error with reaction
Terminal bus cycles are stopped - Start master
- Check bus cable
- Check parameters
(-> Diagnostics data)
- Check configuration
(-> Diagnostics data)
