product details

The warm failover feature was developed for the process control unit interface to minimize the interruption in the flow of exception reports that occurs when the backup process control unit interface re-establishes exception report routes once it becomes the primary process control unit interface. The elapsed time of this interruption is dependent on the number of exception report routes that need to be re-established prior to warm failover or for a cold failover. This interruption may exceed one minute for a process control unit interface with a large configuration. During a warm failover, points configured in a process control unit interface that has failed do not reflect bad quality. in contrast, cold failover protocol dictates that all other nodes mark all exception report data from a process control unit interface that has failed as bad quality until all exception report routes are re-established and new good quality exception reports are received. warm failover allows other nodes to maintain good quality briefly during a warm failover.
