Status/Alarm Timing
Timing A – The PSM buffers an entire power line cycle and takes 11 ms to perform calculations on the waveforms. The new
status bits are available to the application code after the next PLC input data scan.
Total latency = 1-cycle + 11 ms + (0 to PLC scan time)
Update rate = 1-cycle or the PLC scan rate (whichever is longer)
Timing B – The PSM updates this information every 100 ms. The new status bits are available to the application code after
the next PLC input data scan.
