Airlocks are too dispersed for one local board.
Remote I/O serves each area through the Ethernet architecture.
This network separates the master interlock logic from remote input/output equipment installed around a facility. Ethernet links carry the control information between locations, while local connections serve door sensors, locks and operator stations. A modular cabinet arrangement accommodates the distributed equipment. The architecture is intended for larger cleanroom installations that need shared monitoring and engineered sequences across multiple airlocks, rather than a self-contained controller serving only one vestibule.
