INPUTS
Input Properties Screen
Each Input has a respective Properties
screen associated with it. As every Input
is different in nature from another, the
Properties screens will differ from Input to
Input. All Input Properties screens share
some common options, however, that
apply to their respective Tasks.

All Inputs have either a live, updating Value or a manually retrieved Value in the bottom
right corner of their screens. Manually retrieved Values (such as an SDI-12 Sensor) will have a
Test button next to the Value label that can be pressed to retrieve a new value. Shown Values
will have any Slopes, Offsets, or Custom Functions already applied to their measured value.
Task
Type
Shows the Task name associated with
this Input.
Provides available options for when
this Input is run. Generally only the Timed Scan option will be available and is an interval at
which a new measurement will be retrieved. To modify the Scan Rate or scanning schedule,
press the Edit of Advanced (Adv) button next to the listed rate. Rates are in a 24-hour format of
HH:MM:SS.
Digital Input modes of Level and Event Counter have another Type available called Edge

™

Digital Edge rises or falls and runs all Outputs for the Edge Triggered Task.
