MANAGING TASKS
28
Each Task can have zero or more Outputs
as shown on the Edit Task screen. Outputs
typically take the value retrieved from
the Input/Source and use that value in
recording to a data/log file, transmitting
via a radio, setting a 4-20mA current,
etc. To add a new Output, press the Add
Output button. To edit the properties of
an existing Output, select the desired
Output and press the Edit Output button.
Available Outputs are shown on the
Add Output screen. If an option card
is installed, additional Outputs may be
available and are designated by their
Adding Outputs
slot within the system. The above screen depicts an Analog/Digital expansion module installed in
Slot 1.
Select the desired Output and press the OK button to open the Properties for that Output. Deselecting
the checkbox at the bottom of the Add Output screen causes the Edit Task screen to be displayed
rather than the selected Output’s Properties screen.
Some Outputs, such as log files or GOES transmissions, include multiple Tasks as part of their
processing. Each Task that is a part of that process will have an Output associated with the Output.
Oftentimes it is simpler to first create all necessary Tasks with their assigned Inputs,
Output Rates and Conditions
Outputs have a variety of options available
through their Properties screens. The
Properties screens are accessed through
either adding a new Output or pressing
the Edit Output button, after selecting the
desired Output, on the Edit Task screen.
Type
The majority of Outputs run on the
same schedule as their Inputs. This
option can be changed, however, if
the Output should be run at a different
rate and/or based on the true/false
evaluation of a Conditional statement.
