3-4 Digital Input/Counter Functional Block
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.
Inversion Specifies whether or not the data from the digital
input is inverted before further processing is done.
Determines whether a high voltage level is
interpreted as an On state (not inverted) or an Off
state (inverted).
Processing Affects the translation of incoming data to the value
passed to one of the output network variables. There
are nine processing options: Direct, Delayed,
Toggled
, Pulsed, One-Shot, Count, Repeating
Count , On Time, and Frequency. The Direct,
Delayed , Toggled, Pulsed, and One-Shot options
cause the Digital input/Counter functional block to
behave identically to the Digital Input functional
block, and the Control and Analog output network
variables will not be used. See Processing Options in
the next section for a description of the processing
options.
Location The location string for this digital input/counter. This
property can be used to document the associated
hardware’s location within an installation so it can be
easily found. This field may contain up to 30
characters. This value is separate from the device’s
location property.
Processing Options
The following sections describe the processing options selected in the Digital
Input/Counter tab.
Direct
Causes data to be output directly to the digital output network variable after the
debounce and invert functions have executed.
Delayed
Specifies a delay from a change on the input to an update on the digital output
network variable. A change from Off to On is delayed by the time indicated in
the On Delay Time field. A change from On to Off is delayed by the time
indicated in the Off Delay Time field.
Toggled
Causes the digital output network variable value to toggle, or change state, every
time the input data changes from Off to On. For example, if a Digital
Input/Counter functional block is attached to a push button and the functional
