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 institutions, especially for the control of is, weichenantrieben, achszu00e4hlern, freimeldeeinrichtungen, geschwindigkeitsmesseinrichtungen, fahrsperren and safe kontaktabfra gene.the number of prozessanschaltungen to significantly reduce cost and yet to allow kundenabhu00e4ngige solutions, it is proposed that combinable functional modules (3a, 3b, 3c) are provided, which features different prozessa nschaltungen 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 the communication between the computer (2) and each functional module type (3a, 3b, 3c) is identical.the software of each function module (3a, 3b, 3c) prozessanschaltungsunabhu00e4ngig is that the software of the computer (2) contains a prozessanschaltungsunabhu00e4ngige (6a, 6b) and a prozessanschaltungsabhu00e4ngige application software (5a, 5b), in that the communication with the fun ktions modules (3a, 3b, 3c) by the basic software (6a, 6b) is provided.
