11.13.1 Fieldbus communication
Parameter A080
Fieldbus communication can be enabled using param-
eterA080 when bus module BCM400 is connected.
A device name/network name must be entered in the
automation system/BCSoft for the unique identifica-
tion of the control unit (BCU/FCU) in the fieldbus sys-
tem.
Parameter 80 = 0: Off. Fieldbus communication is disa-
bled. Parameterization access using BCSoft via Ether-
net is not possible.
Parameter 80 = 1: with address check. The device
name/network name on delivery, for example for the
BCU 460, is “not-assigned-bcu-460-xxx”. The ex-
pression “not-assigned-” must be deleted or may be
replaced with an individual name. The sequence xxx
must be identical to the address set on the BCM400
using the code switches (xxx= address in the range 001
toFEF).
Code switch setting: upper switch (S1) = 10

Parameter A081
In furnace control systems, consisting of FCU50x and
BCU46x, the SafetyLink communications protocol is
used to transfer safety-critical signals between the
FCU and BCU. The data transfer can be enabled using
parameterA081.
Parameter A081 = 0: Off. No data exchange takes place
via K-SafetyLink.
Parameter A082 = 1: On. Data exchange via K-Safe-
