All five triggering functions and the user-definable condition are consolidated (ORed) and connected to the PMU recorder.
Each trigger can be programmed to log its operation into the event recorder, and to signal its operation via targets. The five
triggers drive the STAT bits of the data frame to inform the destination of the synchrophasor data regarding the cause of
trigger. The following convention is adopted to drive bits 11, 3, 2, 1, and 0 of the STAT word.
Figure 5–50: STAT BITS LOGIC
The trigger reset (drop-off) timer is available for all five triggering functions (FREQ, ROCOF, VOLT, CURR, POWER) in indi-
vidual trigger settings under the TRIGGER DPO TIME setting. This asserts individual trigger operand and overall PMU x
TRIGGERED operand with stat bits 3 and 11 for a fixed interval defined by this setting. If it is required that PMU x TRIG-
GERED operand with stat bits 3 and 11 stay longer than the individual reset timer, then use the PMU x USER TRIGGER
setting assigned with appropriate elements and FlexLogic. In short, in case of USER TRIGGER, the drop-off time needs to
be implemented using FlexLogic.

The user trigger allows customized triggering logic to be constructed from FlexLogic. The entire triggering logic is refreshed
once every two power system cycles.
