Output Properties Screens
Each Output has a respective Properties screen associated with it. As every Output is different in
nature from another, the Properties screens will differ from Output to Output. All Output
Properties screens share some common options, however, that apply to their respective Tasks.
Task: Shows the Task name associated with this Input.
Type: Provides available options for when this Output is run. Generally the Run with Input and
Timed Rate options will be available and will specify the interval at which the retrieved
measurement will be processed by the Output. Run with Input, as its name infers, will run the
Output on the same schedule as the Input Scan Rate. The Timed Rate, however, allows a
different rate, typically a multiple of the Input Scan Rate, to be used. If the Timed Rate is faster
than the Input’s Scan Rate or on a different time interval, values may not be available for the
Output to use. To modify the Timed Rate, 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.
Most Outputs allow a Conditional statement that 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. 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).
