• Check whether the device name/network name
in the network configuration is the same as the
device name saved in the control unit.

! An invalid address has been set on theBCM.
! The address check has been activated on the
control unit by setting parameter A080=1.
• Check whether the BCM address is in the permit-
ted address range (001toFEF).
• Check the value of parameterA080 and adjust
it if necessary.
• Adjust the code switch settings on the BCM to
the device name assigned in the network con-
figuration.

! The BCM has received an incorrect configuration
from the controller.
• Check whether the appropriate GSD/EDS file
has been read into the automation system’s
engineering tool.
• Check the device configuration.

! The device name for the control unit (BCU) in
the engineering tool is invalid or has not been
entered.
! The address check has been activated on the
control unit by setting parameter A080=1.
▷ Device name on delivery:
e.g. for BCU 460 = not-assigned-bcu-460-xxx
(xxx = address in the range 00 to FEF).
▷ The device name must at least consist of the
expression:
e.g. for BCU 460 = bcu-460-xxx.
Depending on the control unit (BCU) in use,
the default value of the address will change,
see also page 4 (Parameter A080 = 2:
Fieldbus communication without address check).
• Delete the expression “not-assigned-” in the
engineering tool or replace it with an individual
name (e.g.Furnacezone-).
• Check whether the device name name in the
network configuration is the same as the device
name saved in the control unit.
• Check the value of parameterA080 and adjust
it if necessary.

! 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.
