Fieldbus configuration (parameter A080)
▷
Depending on the setting of parameter A080,
fieldbus communication may take place with or
without an address check.
▷
Check the value of parameter A080 using BCSoft
and adjust it if necessary.
Parameter
No.
Name
Possible values for bus communication
80
Fieldbus communication
0
= Off
1
= With address check
2
= No address check
▷
For further instructions on setting the parameters,
see BCU 46x, 480 operating instructions, section
entitled “Adjustment”.
Parameter A080 = 0:
Fieldbus communication Off
▷
Fieldbus communication is switched off. Ac-
cess to the unit via Ethernet is still possible using
BCSoft.
Parameter A080 = :
Fieldbus communication with address check
▷
EtherNet/IP
A fixed valid IP address is allocated using the
DHCP server, the engineering tool or BCSoft.
▷
The device name/network name on delivery is:
e.g. for BCU 460: “bcu-460-xxx” (“not-assigned-
bcu-460-xxx” if configured using the engineering
tool).
The sequence xxx stands for the address
set on the code switches of the BCM 400
(xxx = address in the range 001 to FEF).

=> bcu-460-02A
▷
The expression “not-assigned-” must be deleted.
▷
An individual name (e.g. “Zone1-bcu-460-xxx”)
may precede the device name/network name
(e.g. bcu-460-xxx).
▷
The device name must at least consist of the
expression:
e.g. for BCU 465: “bcu-465-xxx”.
▷
The address on the BCM set on the code
switches must be identical to the address (xxx)
entered in the automation system’s network
configuration.
▷
After the code switch settings have been
changed, the control unit must be switched off
and on again to enable the new address setting.
5
Start the network communication.
▷
The BCU powers up. If the IP address is valid,
the program can be started.
Parameter A080 = :
Fieldbus communication without address
check
▷
The device name/network name can be selected
as required.
▷
EtherNet/IP:
if the IP address is invalid, the
BCU automatically starts in DHCP mode so as
to avoid network conflicts. The IP address can be
allocated by the DHCP server or engineering tool.
5
Start the fieldbus communication.
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
,
1
,
2
,
3
or
4
)
is active, the control unit can continue to be
operated via its digital inputs.

BCU waits for connection with the automation
system controller.
•
Check whether the controller is switched on.
•
Check the network wiring.
•
Check the controller’s network configuration.
•
Check whether the device name/network name
in the network configuration is the same as the
BCM address setting.
