3.4.2.4 Message: ChannelData
| Topic Version | 1 | Published | 10/31/2016 | |
| For Standard | ETP v1.1 | |||
Contains an array of <index,value> 2 tuples for one or more channels. Unlike the ChannelDataFrameSet message or DataFrame record, which are structured like the <data/> element of a WITSML V1.4.1 log, there is no requirement that any given channel appear in an individual ChannelData message, or that a given channel appear only once in ChannelData message (i.e., a range of several index values in one message).
Message Type ID: 3
Correlation Id Usage:
If this ChannelData is a response to a ChannelRangeRequest MUST be equal to the message id of the ChannelRangeRequest. Otherwise, MUST be 0.
Multi-part: True
