Firmware characteristics
14 data logs Up to 96 different parameters, factory-set logs ready to use
One 100 ms data log Parameters recorded every 100 ms for events
(CM3350 only)
One min./max. log -
One min./max./avg. log Min./max./avg. values recorded for 23 parameters
at regular intervals from 1 to 1440 minutes
One event log Time stamping to 1 ms, synchronisation 1 ms by GPS
Trend curves Four trend curves: 1 minute, 1 hour, 1 day and 1 month.
Min./max./avg. values recorded for eight parameters:
- every second for one minute for the 1-minute curve
- every minute for one hour for the 1-hour curve
- every hour for one day for the 1-day curve
- every day for one month for the 1-month curve
Forecasting Forecasting of the values for the eight parameters
for the next four hours and next four days
Waveform capture Standard: manual launch, 1 cycle,
128 samples, 63
rd
harmonic
Disturbance: manual launch or by alarm,
128 samples per cycle, adjustable from 12 to 80 cycles,
response time less than 0.5 cycle, number of cycles
before alarm settable from 2 to 10
Alarms Adjustable pickup and dropout setpoints and time delays,
numerous activation levels possible for a given type
of alarm
Four priority levels
Three response times: standard 1 second, fast 100 ms,
disturbance < 0.5 cycle (CM3350 only)
Boolean combination of four alarms is possible using
the operators NAND, OR, NOR and XOR
Digital alarms, e.g. status change of digital inputs
Memory 8 Mbytes standard
Firmware update Update via the communication ports
