7.2.1.1 Recording Channels
The sampled curves of all analog and process signals that have been created are recorded. The
constant sampling rate is 192 samples per nominal cycle. The binary changes are recorded with
a resolution of 1 kHz and a maximum of 250 changes per second and DAU.
The channels of all active DAUs are always recorded in the fault record, even if there is no limit
value violation for the channel.
Depending on the DAU different measured values are recorded:
‰
Alternating voltage with VCDAUs and VDAUs
‰
Alternating current with VCDAUs and CDAUs
‰
Process signals (direct voltage/direct current) with DDAUs
‰
Binary signals with VCDAUs, VDAUs, CDAUs, DDAUs and BDAUs
‰
Quality tracks with VCDAUs, VDAUs, CDAUs, DDAUs and BDAUs
Tables 7-9 and 7-10 give an overview of the recorded values of the DAUs.
