METHOD FOR FUNCTIONALLY SECURE EXCHANGE OF INFORMATION ACCORDING TO A SAFETY STANDARD

摘要

A method for the functionally safe exchange of information between at least three safety controllers according to a safety standard, designed for the control of an electrical consumer that is functionally safe according to a safety standard, is intended to allow the interconnection of a comparatively large number of safety controllers in a network while at the same time providing secure communication. For this purpose, a master (M1) is provided, and a plurality of safety controllers is designed as a slave (S1... SN), wherein data packets (DS1... DSN) are transmitted by a plurality of slaves (S1 receive the master (M1), the master (M1) connects the data packets (DS1 ... DSN) to a collection data packet (DM1), and sends the aggregate data packet (DM1) to all slaves (S1 ... SN).
