7.3 Continuous Recorder
The SIMEAS R-PMU features six continuous recorders: 5 Continuous Recorders (CR) and the
Event Recorder (ER). Continuous Recorders are used for data acquisition of the analog values
over longer periods of time, in order to be able to perform long-term analyses of the system
behaviour. The Event Recorder records the state changes of binary signals. Table 7-22 provides
an exact overview of the available recorders.
The individual recorders use different methods of data acquisition:
‰
The CPR records the values as instantaneous values at the end of the parameterized
recording interval.
‰
The CFR, CRR, CQR and CDR recorders calculate the arithmetic mean of the cycle-based
measured values using the averaging interval (see figure 7-22).
