K5BMC system can be configured as centralized or as well as distributed interlocking system. It is very much suitable for distributed type electronic interlocking system. It is very much effective in Auto section / IBH concept of signalling. It is based on Two Out of Two (2oo2) architecture with a hot standby provision and automatic change-over facility. Logic sub rack (LK7-C) uses two independent channels for computing the vital interlocking. Hot standby with automatic change-over facility is provided. Redundant optical fiber communication provided between LK7-C and Field units (ET/EP-5 sub rack) & CCIP (ET/EM-6 sub rack. In Logic Sub-rack for handling communication 2 communication cards (FSIO and FSIO-EX) used for each system. In generally FSIO card used for communication between Logic sub rack and Field units (ET/EP-5) and FSIO-EX cards used for communication between Logic sub rack and CCIP & operator VDU.LK7-C to Field units & LK7-C to CCIP units connected in daisy chain topology. ET/EP-5 sub rack provides interface between filed gears and logic sub rack. ET/EP-5 Sub rack consist of Input & output card (ETPIO2) and Power Supply and communication card (LINE2B). LINE2B cards used for communication between field gears and logic sub rack. LINE2B card have 2 optical fiber channels for communication. ET/EM-6 sub rack provides interface between CCIP and logic sub rack. ET/EP-6 sub rack consist of Input & output card (MMIF2) and Power Supply and communication card (LINEM2).
