Data Acquisition System (DAS) and APICOM Teledyne API – Model T300/T300M CO Analyzer
168
Note DAS operation is suspended whenever its configuration is edited using
the analyzer’s front panel and therefore data may be lost. To prevent
such data loss, it is recommended to use the APICOM graphical user
interface for DAS changes (Sections .
Please be aware that all stored data will be erased if the analyzer’s disk-
on-module or CPU board is replaced or if the configuration data stored
there is reset.
Note The DAS can be disabled only by disabling or deleting its individual data
channels.
7.1. DAS STRUCTURE
The DAS is designed around the feature of a “record”. A record is a single data point.
The type of data recorded in a record is defined by two properties:
PARAMETER type that defines the kind of data to be stored (e.g. the average of gas
concentrations measured with three digits of precision). See Section 7.1.6.
A TRIGGE
R event that
defines when the record is made (e.g. timer; every time a
calibration is performed, etc.). See Section 7.1.5.
The specific PARAME
T
ERS and TRIGGER events that describe an individual record
are defined in a construct called a DATA CHANNEL (see Section 7.1.1). Each data
channel is related one or mo
re parameters with a specific trigger event and various other
operational characteristics related to the records being made (e.g. the channels name,
number or records to be made, time period between records, whether or not the record is
exported via the analyzer’s RS-232 port, etc.).
