Process connections for the safe operation of safety and security installations

摘要

the invention relates to a prozessanschaltung for the safe operation of sicherungstechnischen installations, in particular for the control signals, weichenantrieben, achszu00e4hlern, freimeldeeinrichtungen, geschwindigkeitsmesseinrichtungen, fahrsperren and safe kontaktabfragen, components are formedhow to control and monitor at least with a secure server (2) are connected.with less overall prozessanschaltungen the schaltungsaufwand for communication between a secure computer and the components to reduce, it is proposed that combinable functional modules (3a, 3b, 3c) are provided which each different functionalities chen prozessanschaltungen together and, in particular, the functionalities of pru00fcfschaltungen,circuit breakers, filters, digital inputs and outputs, computers and communication interfaces (2) that at least one function module (3a, 3b, 3c), a secure computer (2) and that the communication of the secure computer (2) with the other functional modules over a serial bus (5) ) is done.
