Signaling system for control/monitoring systems, has interface unit coupled by control bus to bus controller(s) coupled by desktop bus to field controller(s) with microprocessor, and signaling unit(s)

摘要

The system has a number of signaling devices (11) and senders (12) and a processor-controlled interface unit (4) coupled to a central control computer (1) via a serial data link (3). The interface unit is coupled via a control bus (7) to one or more bus controllers (8), of which each is coupled via a desktop field bus (9) to one or more desktop field controllers (10) containing a microprocessor and driving one or more signaling devices (11).
