2 CHECKING THE USAGE
The bus module BCM400..B1 is used as a commu-
nication interface for burner control units BCU460,
BCU465 or BCU480 for connection to a fieldbus
interface via PROFIBUS.
Networking via the fieldbus enables the BCUs to be
controlled and monitored by an automation system
(e.g.PLC). The communication network must be
protected against unauthorized access.
This function is only guaranteed when used within
the specified limits– see page 6 (8 Technical
data). Any other use is considered as non-compliant.

2 Connect the shield on both sides and over a
wide area with shield clips in the plug.
➔Ensure there is an equipotential bond between
the devices.
3 Switch on the terminal resistors on the first and
last subscriber in the segment.
4 Wire control signals that are relevant for safety,
such as the safety interlocks and high tempera-
ture, separately.
➔The purge signals can be transferred via the
bus communication or by a separate cable via
terminal.
➔Protect the communication network against
unauthorized access.
6 COMMISSIONING
WARNING
Risk of explosion!
Do not enable the BCM and control unit (BCU) for
operation until the parameter settings and wiring
are correct and the faultless processing of all input
and output signals has been ensured.
In the event that the bus communication is faulty
or interrupted, or the communications data is inva-
lid, or during initialization, the signals received from
the controller are interpreted as“0”. If the control
unit is activated using the inputs at the terminals
during this time, the normal program runs. Be sure
to take the settings of parameters A085 to A089
into account.
➔Fieldbus communication can be configured
using the engineering tool of the automation
system.
➔The BCSoft operating instructions and software
can be downloaded from www.docuthek.com.
1 Set parameter A080 = 2 (Fieldbus communica-
tion without address check).
2 Check the code switch settings (001 to 125) on
the BCM for PROFIBUS communication
between BCSoft and the control unit.

➔Each code switch setting combination may only
exist once within the fieldbus system.
➔Each device name/network name may only be
allocated once within the fieldbus system.
➔All the device-specific parameters for the
BCM..B1 are saved in the device master data
file(GSD): download from www.docuthek.com.
3 Copy the GSD file.
➔The steps required to copy the file are described
in the instructions for the automation system.
4 Configure the PROFIBUSDP using the
appropriate tools for the automation system you
are using.
➔The BCM..B1 will automatically identify the baud
rate– max.1.5Mbit/s.

BCM 400..B1 · Edition 03.24
EN-4
➔The max. range per segment depends on the
baud rate:
Baud rate [kbit/s]
93.75 187.5 500 1500
Range [m (ft)]
1200
(3937)
1000
(3280) (1312) (656)
➔For instructions on commissioning the control
unit, see operating instructions “Burner control
unit BCU46x,480”.
➔The ranges can be increased by using repeat-
ers. No more than three repeaters should be
connected in series.
➔The BCU with BCM..B1 indicates –– when the
mains switch has been switched off. This signals
Standby mode. Bit6=0. The bus interface is
still supplied with voltage to maintain the function
of the communications system. The control out-
puts of the BCU (valves, ignition transformer) are
electrically isolated from the mains voltage.
5 Apply voltage to the terminals.
6 Switch on the BCU.
➔The display –– will go out.
➔Bit 6 of input byte 0 is set.
7 Start the PROFIBUS communication.
➔As soon as the flashing display n 0goes out and
the indication 00 appears in the display, the data
traffic is operating.

7 ASSISTANCE IN THE EVENT OF
MALFUNCTION
DANGER
Electric shocks can be fatal!
Before working on possible live components,
ensure the unit is disconnected from the power
supply.
Fault-clearance must only be undertaken by
authorized trained personnel.
➔Faults may be cleared only using the measures
described below.
➔If the control unit BCU does not respond even
though all faults have been remedied: remove
the unit and return it to the manufacturer for
inspection.
➔If a fault message (n 0) is active, the control unit
can continue to be operated via its digital inputs.
? Faults
! Cause
• Remedy
? The display on the control unit blinks and
indicates n 0.
! No connection established between BCU
andPLC.
• Check the wiring.
• Check the PLC program to ensure that the
network name and IPconfiguration of the
BCU are valid.
• Switch on the PLC.
Or
? A bus fault is indicated on the automation
system.
! The PROFIBUS DP data traffic has suffered a
fault.
! Bus cable interrupted.
• Check cable.
! Incoming and outgoing bus cables confused in
the plug.
• Check the wiring.
! A and B cables confused.
• Check the wiring.
! Terminal resistors connected incorrectly.
• Switch on the terminal resistors on the first
and last subscriber in the segment and switch
them off for all other subscribers.
! Incorrect PROFIBUS address set.
• Correct the address setting – switch the unit
off and then on again to save the address.
! Bus cables too long.
• Reduce cable length or baud rate – see page
3 (6 Commissioning).
➔If the transfer rate is reduced, remember that this
will increase the signal running times to and from
the individual units.
! Poor shielding.
• Check whether the shield is connected to the
shield clips in the PROFIBUSDP plugs in full
and over a wide area.
! Poor equipotential bond.
• Check whether the PROFIBUSDP shield is
connected at all points to the same ground
potential via the grounding system of the units.
• If necessary, an equipotential bonding cable
must be laid.
➔If faults occur sporadically in the PROFIBUSDP
system, and are only indicated briefly in the bus
master, the following points in particular should
be checked:
– Terminal resistors,
– Shield,
– Cable lengths/routes,
– Equipotential bond,
– Use of interference-suppressed spark electrode
terminal boots (1kΩ).
➔For information on planning and the structure of
a PROFIBUS network and the components to
be used (e.g. cables, lines and switches), see
www.profibus.com or the instructions for the
automation system.
? The display on the control unit blinks and
indicates Eb E.
! Internal communication with bus module has
suffered a fault.
• Connected control elements must be
equipped with protective circuits in accord-
ance with the manufacturer’s instructions.
➔This prevents high voltage peaks which can
cause malfunctioning of the BCU.
• Use interference-suppressed terminal boots
(1kΩ).
• If the fault cannot be remedied by doing this,
remove the unit and return it to the manufac-
turer for inspection.
! Bus module is defective.
• Replace the bus module.
For other control unit fault messages, see
BCU46x,480 operating instructions, section
entitled “Assistance in the event of malfunc-
tion”.
