has a higher priority. When a WFR is already in progress, all other WFR commands will be ignored until
the present recording is completed.
The programming of the WFR is supported over communications, the built-in Web Interface and the
optional HMI. The WFR provides the following setup parameters:
Parameter
Value
WFR Format
Samples/Cycles x # of Cycles: 0 = 16x600, 1 = 16x300, 2 = 32x300, 3 = 32x150, 4 = 64x150, 5 = 64x75
Pre-fault Cycle
0 to 10 (cycles)
Trigger Setup
Dip/Swell, U & I Alarm, Unbal. & Harmonics, Power Alarm, Freq. Alarm, DI Alarm

WFR Logs can be retrieved via communications by our PecStar® iEMS, displayed on or exported from
the Web Interface.

4.7.5 Data Recorder (DR)
PMC-592’s
DR
records the real-time measurement for Mains-I, Mains-II, SMs and VMs since Firmware
V1.00.04. There are 10
DR
s
of 64 parameters each that can be individually programmed to record
different parameters at different time intervals, which may vary from 60 to 345600 seconds. The PMC-
592 can retain the DR Logs for 45 days when the recording interval is set to 1 minutes. The recorded
data is stored in non-volatile memory and will not suffer any loss in the event of a power failure. If
storage is full, the newest log will replace the oldest on a first-in-first-out basis. Also, recording mode
can be set as Stop-When-Full, which means when storage is full, the DR will stop.
The programming of the
DR
is only supported over communications. Each DR provides the following
setup parameters:
