3.2.5 Device Event Response Time

This parameter specifies the maximum time required by a BECO2200 device to recognize and to be able to report an event. This parameter is used to determine what SOE event in the system is the oldest, in order to sort and distribute the time-tagged binary input data accurately.

Event Occurs at Device

T1

T2

In the above figure, it takes the BECO2200 device t2-t1units of time to recognize and buffer the event data. If the BECO2200 DCA had polled the device at time T, which was after t1 but prior to time t2, no event data would have been reported, event though an event has occurred.

The BECO2200 DCA will, therefore, distribute time-sorted SOE events up to the time T- (t2- t1), instead of up to the time T.
