Group Logic The sixteen Group Logic statements reside in a slower processing thread with-
in the relay protection algorithms. The processing cycle happens once every
half second (0.5 s). When using ProLogic statements you must keep in mind
that a latch or dropout timer should be used if the initiating condition does not
last at least 0.5 seconds.

Output Matrix
Figure 5.20: Output Matrix 1
The output contact matrix determines which function initiates which output re-
lay. All output relays have a fixed 0.1 second stretch time. Functions can also
initiate fault recording, recloser blocking, recloser initiation and/or breaker
failure initiation.
For a particular function to operate correctly, it must be enabled and
must also have its logic output assigned to at least one output contact
if it is involved in a tripping function.
