iDAS data are defined by the PARAMETER type and are stored through different triggering EVENTS
in data CHANNELS, which relate triggering events to data parameters and define certain
operational functions related to the recording and reporting of the data.
6.12.1.1. iDAS Channels
The key to the flexibility of the iDAS is its ability to store a large number of combinations of
triggering events and data parameters in the form of data channels. Users may create up to 20
data channels and each channel can contain one or more parameters. For each channel one
triggering event is selected and up to 50 data parameters, which can be the same or different
between channels. Each data channel has several properties that define the structure of the
channel and allow the user to make operational decisions regarding the channel (Table 6-22).
