BECKHOFF BC2000 - Manual (Page 14)

Basic Principles
13 BC2000
Error code Error
argument Description Remedy
Persistent,
continuous
blinking EMC problems - Check power supply for overvoltage or
undervoltage peaks
- Implement EMC measures
- If a terminal bus error is present, it can be
localised by a restart of the coupler (by
switching it off and then on again)
1 pulse 0
1
2 EEPROM checksum error
Inline code buffer overflow
Unknown data type - Set manufacturer’s setting with the KS2000
- Connect fewer terminals; too many entries in
the table for the programmed configuration
- Software update required for the coupler
2 pulses 0
n (n > 0) Programmed configuration
Incorrect table entry / bus coupler
Incorrect
table comparison
(terminal n)
- Check programmed configuration for
correctness
- Incorrect table entry / bus coupler
3 pulses 0 Terminal bus command error - No terminal connected; attach terminals.
- One of the terminals is defective; halve the
number of terminals attached and check
whether the error is still present with the
remaining
terminals. Repeat until the
defective terminal is located.
4 pulses 0
n Terminal bus data error
Break behind terminal n
- Check whether the n+1 terminal is correctly
connected;
replace if necessary.
– Check whether the end terminal 9010 is
connected.
5 pulses n Terminal bus error with register
communication with terminal n Replace terminal n.
9 pulses 0
n
Checksum error in program flash
memory
Terminal n is not consistent with the
configuration that existed at boot
image entry - Set manufacturer’s setting with the KS2000
- Set manufacturer's setting with the KS2000,
which will delete the boot project
14 pulses n Terminal n has the wrong format - Start the coupler again, and if the error
occurs again then exchange the terminal
15 pulses n Number of terminals is no longer
correct - Start the coupler again, and if the error
occurs again after this, use the KS2000
software to set manufacturer’s settings
16 pulses n Length of the terminal bus data is no
longer correct - Start the coupler again, and if the error
occurs again after this, use the KS2000
software to set manufacturer’s settings
Error location
The number of pulses indicates the position of the last bus terminal before
the fault. Passive bus terminals, such as a power feed terminal, are not
included in the count.
When the error is rectified, the bus terminal controller does not stop
flashing. Operating state of the bus terminal controller: „Stop“. The bus
terminal controller can only be re-started by switching off the supply
voltage.
Fieldbus errors The fieldbus status LEDs indicate the operational state of the fieldbus. The
functions of the Beckhoff Lightbus are indicated by the „CYC“, „ERR“ and
„WD“ LEDs.
The meaning of the first three LEDs is:
CYC
the LED lights up for the duration of each telegram
ERR is switched on by a faulty telegram, and switched off again by
three correct telegrams
WD watchdog, lights for 100 ms after the bus terminal controller has
been addressed
