Managing Tasks

Run with Input

Sets the Output to run on the same schedule as the Input. The Input’s measurement schedule can

be viewed by pressing the View button.

Timed Rate

Sets the Output to run on a specified schedule, regardless of the Input Scan Rate. Note that this

interval should be a multiple of the Input’s Scan Rate. If the Timed Rate is faster than the Input’s

Scan Rate, values may not be available for the Output to use. To modify the Timed Rate (or other

Advanced Scanning Options), press the Edit button next to the listed rate. Rates are in a 24-hour

format of HH:MM:SS. Timed Rates can be useful, for example, with a Log To File Output when

processing functions (such as minimums and maximums) are being used. An Input could be set

at a 1-minute (00:01:00) Scan Rate with a Log To File Timed Rate set to 5-minutes (00:05:00). In

the Properties for the Log File, the Tasks could be given functions to avg, min, or max the previous

five (1-minute) values.

Conditional

A Conditional statement can be used to determine if the Output should be run. If the resulting

value is greater than zero, the Output will proceed. Otherwise, the Output will not be run and

the next Output or Task will be processed. A logical statement that evaluates to true or false (e.g.

Battery > 0) can also be used and is processed accordingly. The setup of a Conditional statement

is nearly identical to that of a Custom Function, minus the RawValue reading of the current Task

(as the measurement will have already been made and calculated at this stage).

Removing Outputs

An Output can be removed from a Task

by selecting the desired Output on

the Edit Task screen and pressing the

Remove Output button. A prompt will

appear verifying this is correct. Removing

an Output from a Task will only affect that

Task. For example, removing a Log To

File Output from myTask will only prevent

myTask from being recorded to that

log file on future scans. All other Tasks

recording to that log file will continue to

log as expected.
