7.3.6 Test Run Stopper
The Test Run Stopper channel stops a test run when the input channel becomes
TRUE.
NOTE
To automatically start a test run after the Test Run Stopper stops a run, use the remote
control option with the run control switch always in the run position. For more
information on remote control, see “Using Remote Control Operation” on page 85.
NOTE
The test run does not stop immediately when the input channel becomes TRUE.
Because the input channel is processed in frames that can be buffered, the test run
typically stops in a fraction of a second after the input channel becomes TRUE. In the
worst case, assume that several seconds could elapse before the test run actually
stops.
Input Channel
The input channel data type must be 8-bit unsigned (logical).
Output Data Type
The output channel data type is 8-bit unsigned (logical).
Application Note: Stopping a Test After a Defined Time Period
To stop a test run after a certain amount of run time, do the following: Define a Time Channel computed channel (see “Time
Channel” on page 150) and select the 32-bit float data type option. Then define a Desk Calculator computed channel (see
“Desk Calculator” on page 130) with an expression such as
ElapsedTime >= 600
, where
ElapsedTime
is the ID of the
Time Channel, and 600 seconds is the desired test run duration.
To limit the data stored in any DataMode to the exact test run duration specified, use the gate triggering options, using the
Desk Calculator computed channel defined above as the trigger channel.
7.3.7 Power Saver
The Power Saver channel enables the eDAQ power save mode when the input
channel becomes TRUE and disables the power save mode when the input channel
becomes FALSE.
NOTE
The power save mode option must be selected to use this computed channel. For
more information on enabling the power save mode, see ECPU or ELCPU.
