Operating Instructions Model 6200E Instruction Manual
120 M6200E Rev: A1
(Section 6.11). The APICOM manual, which is included with the program, contains a more detailed
description of the iDAS structure and configuration, which is briefly described in this section.
The M6200E is configured with a basic iDAS configuration, which is enabled by default. New data
channels are also enabled by default but each channel may be turned off for later or occasional
use. Note that iDAS operation is suspended while its configuration is edited through the front
panel. To prevent such data loss, it is recommended to use the APICOM graphical user interface for
iDAS changes.
The green SAMPLE LED on the instrument front panel, which indicates the analyzer status, also
indicates certain aspects of the iDAS status:

LED STATE IDAS STATUS
Off System is in calibration mode. Data logging can be enabled or disabled for this
mode. Calibration data are typically stored at the end of calibration periods,
concentration data are typically not sampled, diagnostic data should be
collected.
Blinking Instrument is in hold-off mode, a short period after the system exits
calibrations. IDAS channels can be enabled or disabled for this period.
Concentration data are typically disabled whereas diagnostic should be
collected.
On Sampling normally.
The iDAS can be disabled only by disabling or deleting its individual data channels.
6.11.1. 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.
6.11.1.1. 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 6-20).
