Digital Input/Counter
The Digital Input/Counter tab, pictured below, provides a graphical
interface to the LonPoint Digital Input/Counter (DC) functional block. It allows
the user to determine how data from a hardware digital input is interpreted and
what value is sent over the network on the Digital Input/Counter functional
block’s output network variables.
The data flow in this tab is left to right. The raw digital input signal is checked
against the input voltage threshold in order to determine the logical state of the
input (on or off) and then can be modified by the debounce configuration
property, then passed to the configurable inversion function, then passed to the
remaining processing steps. Click the Control and Analog Output network
variable buttons to change the types of these network variables.
Use the plug-in to set the following configuration properties:
Input Type Determines the voltage threshold levels which trigger
a state change. The value may of Dry Contact, 5V,
12V, 24V, or 31V. Use Dry Contact to determine if a
relay or switch has been closed.
Debounce The debounce time for the digital input. This is the
amount of time, in milliseconds, that the input must
