Safe communication in distributed control systems

The publisher/subscriber communication principle is used universally on SafetyNET p. To enable the publisher/subscriber approach to also be used for safe communication, some new security mechanisms have been developed for SafetyNET p. For example, telegram delays can be managed by a runtime measurement initiated by the receiver. The advantage over previous standard solutions is that the transmitter of the message does not need to know the receiver. So the publisher/subscriber approach can also be applied in safety technology, which enables distributed, safe control systems.
