Digital Input
The Digital Input tab, pictured below, provides a graphical interface to the
LonPoint Digital Input (DI) functional block. It allows you to determine how
data from a physical digital input is interpreted and what value is sent over the
network on the DI functional block’s output network variable.
The data flow in this tab is left to right. The raw digital input signal can be
modified by the debounce configuration property, then passed to the
configurable inversion function, then that data is passed to the remaining
processing steps.
Use the plug-in to set the following configuration properties:
Debounce The debounce time for the digital input. This is the
amount of time, in milliseconds, that the input must
remain constant for the value to be passed on to the
rest of the functional block. Set this value to 0 to
turn off the debounce function.
Invert Specifies whether or not the data from the digital
input is inverted before further processing is done.
Location The location string for this digital input. This
property can be used to document the associated
sensor’s location within the plant so it can be easily
