Checking the usage
The bus module BCM 400 is used as a communica-
tion interface for burner control units BCU 4xx for
connection to a fieldbus interface via PROFINET or
EtherNet/IP.
Networking via the fieldbus enables BCU 4xx units
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 5 (Technical data). Any
other use is considered as non-compliant.
