System default valve control setting
●
The small setting block outside the main setting frame in the previous
figure, is used to set the default system status for sampling mode. Double
click the setting block. The subpanel pops up for the valve control setting
"Digital Output Settings" for the sample mode, as shown. Users can set or
adjust the context in each of the boxes to ensure the correct function of the
solenoid valves. Be cautious that the proper setting is already checked and
tested by manufacturer. An incorrect change would give rise to a system
malfunction.
Mode "output" is chosen to define the digital I/O channel as output.
"Channel Description" assigns the corresponding National Instrument
Board channels to control the solenoid valve operation. "Pattern" takes hex
number to trigger all related channels. In this case, this setting is to trigger
the sample valve to open and shut down the zero air flow into the gas cell,
while all other control valves are closed. "Delay" box is the delay time
setting in the unit of "ms" (milliseconds).
System running status setting
●
The "System Running Status" is the top setting block inside the main
setting frame. It is configured to display live system running status, such as
the date, time, and current interferometer status. It is not adjustable by
users.
Modbus Sensor setting
●
"ModbusMultiSensor" setting block is right below the "System running
Status" setting. This setting is used to log six monitored parameters into the
"cons" files. They are gas cell temperature, sample temperature, short inlet
sample line temperature, heated box temperature, short outlet sample line
