The binary channels are sampled once per task execution of the disturbance recorder.
The task execution interval for the disturbance recorder is the same as for the
protection functions. During the COMTRADE conversion, the digital status values
are repeated so that the sampling frequencies of the analog and binary channels
correspond to each other. This is required by the COMTRADE standard.
The disturbance recorder follows the 1999 version of the
COMTRADE standard and uses the binary data file format.
