6.10.1. iDAS Structure
The iDAS is designed around the feature of a “record”. A record is a single data point of one
parameter, stored in one (or more) data channels and generated by one of several
triggering event. The entire iDAS configuration is stored in a script, which can be edited
from the front panel or downloaded, edited and uploaded to the instrument in form of a
string of plain-text lines through the communication ports.
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.
6.10.1.1. 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 are allowed (the M9110EH has
around 25), which can be the same or different between channels. Each data channel has
several properties that define the structure of the channel (Table 0-20).

Property Description Default Setting Range
NAME The name of the data channel. “NONE” Up to 6 letters and
digits are displayed
on the front panel
(use more with
APICOM).
TRIGGERING
EVENT The event that triggers the data channel to
measure and store its data parameters. See
APPENDIX A-5 for a list of available
triggering events.
ATIMER Any allowed event.
NUMBER AND
LIST OF
PARAMETERS
A User-configurable list of data types to be
recorded in any given channel. See
APPENDIX A-5 for a list of available
parameters.
PMTDET Any available
concentration,
temperature,
pneumatic or
diagnostic
parameter.
STARTING DATE The starting date when a channel starts
collecting fata 01-JAN-03 Any actual date in
the past or future.
SAMPLE PERIOD The amount of time between each data point
that is averaged into one mean reported
every REPORT PERIOD.
000:01:00 000:00:01 to
366:23:59
(Days:Hours:Minut
es)
REPORT PERIOD The amount of time between each channel
data point.

366:23:59
(Days:Hours:Minut
es)
NUMBER OF
RECORDS The number of reports that will be stored in
the data file. Once the specified limit has
been exceeded, the oldest data are over-
written to make space for new data.
100 1 to 1 million,
limited by available
storage space.
