Parameter
Description
Filter Intervals
Used with the Filter parameter to define a time delay in
detecting the discrete input's On status:
• 0.1 seconds: Each filter interval is 100 milliseconds.
• 15.0: Each filter interval is 15 seconds.
Input
Controls the polarity of the discrete input, or how the discrete
input represents Closed and Open.
• Normal: On = Closed; Off = Open.
• Inverted: On = Open; Off = Closed.
Filter
Defines the number of filter intervals that the discrete input must
remain in the On (active) state before the state is detected and
the discrete input status is defined as On.
Enter a value between 0 and 255:
• 0 requests the shortest possible period.
• 255 requests the longest possible period.
Accumulated
The number of times the discrete input has switched from Off to
Value
On.
On Counter
Displays the number of periods that the Status parameter has
been in the On state. A period is defined as 100 milliseconds.
Off Counter
Displays the number of 100 millisecond periods that the Status
parameter has been in the Off state.

Comments
Filter Intervals and Filter apply
only to detection of the On state.
Detection and response to the Off
(inactive) state occurs with no
artificial delay.

Maximum value: 4,294,967,295.
Rolls over to 0 when maximum
value is reached. Can be reset to
any desired start number.
