OUTPUTS

Output Properties Screen
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).
Log To File
Measurements retrieved from Inputs can be stored in the internal memory of the System 5000
™
through logging to the Log To File Output. Multiple log file configurations can be created,
allowing different sensors to be logged to different files. Data is recorded to log files after each
scan and are re-created if ever deleted or renamed. These log files can be easily viewed and/or
retrieved at any time via the Data File Manager on the Main Menu. As each log file
configuration is stored separately, every log file can be fully customized for its own purpose.
