Clicking on the Add New Analyser button will add a new analyser to the system,
which will default to an Ecotech Termination Panel (TP) with no channels configured
and default communication settings. The Delete Analyser button will delete the
currently selected analyser from the system including any channel configurations it
has. The OK and Cancel buttons function as described earlier, except that clicking the
OK button will also restart the server to reflect any changes.
4.2.1 Information
When opened, the Analyser Parameters window will display the Information tab for
the first analyser in the system. Figure 24 shows a typical opening screen for an
Ecotech Termination Panel. Entries can be made in the following fields:
The Label text box allows you to enter a label that will help you to identify the
analyser.
The Manufacturer list box shows the names of manufacturers of analysers which
WinAQMS Mini DAS supports.
The Model list box shows the analyser models corresponding to the Manufacturer
list box that WinAQMS Mini DAS supports. The image to the right changes to
match the selected model.
The Device ID is used by WinAQMS Mini DAS when communicating with the
analyser. It also identifies an individual analyser when several analysers are multi-
dropped (that is, communicating on the same serial port).
Data Request Period (sec) is the time in seconds between requests for data made
by WinAQMS Mini DAS to the analyser.
Maximum Response Time (sec) is the time in seconds that WinAQMS Mini DAS
will wait for the analyser to respond. If this time passes with no response,
WinAQMS Mini DAS will set its data value for the reading to NULL. If
Maximum Response Time is set too low then the analyser will not have sufficient
time to respond in time so WinAQMS Mini DAS will report NULL‟s even if the
analyser is functioning normally.
Request Delay (mSec) is the time in milliseconds that WinAQMS Mini DAS will
wait before issuing the data request to the serial port. This parameter is useful
when several analysers are being multidropped and analysers have a delay in
transmitting and receiving information.
Analyser Description is a brief description of the function of the analyser model
selected.
For Opsis analysers there is no Device ID but there are Station # and Data Update
Timeout fields. The Station # field should be set according to what is set on the Opsis
analyser. As the Opsis often will not update its data value the Data Update Timeout is
used as the length of time (in MM:SS format) to keep using the last valid data value
before setting the current data to a null value.
For Thermo Environmental analysers the Device ID field becomes a dropdown list for
the common Thermo Environmental analyser types of 42C (ID 170), 43C (ID 171),
48C (ID 176) and 49C (ID 177) as well as an Other list item for Thermo
Environmental analysers that use ID‟s other than the ones listed.
