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.
