C.18.5.1.1 Referenced Waveform Channels

Referenced Waveform Channels (0040,A0B0) is a multi-value Attribute that lists the channels referenced. Each channel is specified as a pair of values (M,C), where the first value is the Item number of Waveform Sequence (5400,0100) in the referenced object (i.e., the Multiplex Group Number), and the second value is the Item number of Channel Definition Sequence (003A,0200) (i.e., the Channel Number) within the multiplex group.

If the specified channel number is 0, the annotation applies to all channels in the specified multiplex group.

Note

As an example, an annotation that applies to the entire first multiplex group and channels 2 and 3 of the third multiplex group would have Referenced Waveform Channels (0040,A0B0) value 0001 0000 0003 0002 0003 0003.
