SIL3 BMS systems supervise of all safety trips of boilers and burner logics (pre-purge, light-off, shutdown, etc.) as per EN normative. BCS systems manage boilers process control and burners combustion control. Common part system is dedicated to control of all common utilities and electrical system distribution. Electrical system distribution management allows manual and automatic change-over of power sources for medium voltage and low voltage systems.
BMS and BCS are connected with redundant point-to-point Ethernet link. Data exchange protocol is ModBus TCP. All analog I/Os are isolated with Pepperl & Fuchs galvanic isolators.
