摘要 |
A system for centralized reporting of alarm conditions in a multinode data handling system includes an alarm concentration unit at each node of the system for collecting alarm conditions. Each alarm concentration unit is coupled to a signal transmission unit which generates alarm messages and transmits the messages to a centralized node. The centralized node includes means for comparing each received messages with previously received messages stored in a memory and for amending the memory when the most recent received message differs from a previously stored message.
