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 communications network must be
protected against unauthorized access.
This function is only guaranteed when used within the
specified limits– see page6 (Technical data). Any
other use is considered as non-compliant.

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.
If the control unit is activated via the inputs at the
terminals in the event of faulty or interrupted bus
communication, invalid communications data, or
during initialization, 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.
 Set parameter A080 = 2 (Fieldbus communica-
tion without address check).
 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 a device master data
file(GSD): download from www.docuthek.com.
 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 appropri-
ate tools of the automation system you are using.
▷ The BCM..B1 will automatically identify the baud
rate (max. 1.5 Mbit/s).
▷ 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)
400
(1312)
200
(656)
▷
For instructions on commissioning the control
unit, see operating instructions “Burner control
unit BCU46x,480”.
▷
The ranges can be increased by using repeaters.
No more than three repeaters should be con-
nected 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 func-
tion of the communications system. The control
outputs of the BCU (valves, ignition transformer)
are electrically isolated from the mains voltage.

Assistance in the event of
malfunction
DANGER
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is discon-
nected from the power supply.
Fault-clearance must only be undertaken by author-
ized 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 (
0
) is active, the control unit
can continue to be operated via its digital inputs.
? Faults
! Cause
• Remedy
0
? The display blinks and indicates 0 .
! No connection established between BCU and
PLC (controller).
• Check the wiring.
• Check the PLC program to ensure that the net-
work 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 (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 con-
nected 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.
EE
? The display on the control unit blinks and
indicates E E .
! Internal communication with bus module has
suffered a fault.
• Connected control elements must be equipped
with protective circuits in accordance 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 manufacturer
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 malfunction”.
