DIO#.FILTER

Description

Gets or sets the digital input filter when specified channel is configured as a digital input (see DIO#.DIR). The digital filter blocks input changes (rising or falling edges) until the minimum pulse width is exceeded. The +/- tolerance listed is the sample period (uncertainty) of the filter.

Value	Description	Min PulseWhen the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated Width	Typical Use
0	Unfiltered	>40ns	RS485 inputs
4	Ultra fast	>240ns +/- 40ns	Fast Optos
1	Fast	>10.24 µs +/- 0.64 µs	Fast Optos
2	Standard	>163µs +/- 10.24µs	Slow Optos
3	Slow	>2.62ms +/- 0.16384ms	Mechanical switch

Usage

When DIO#.DIR = 0 (input) then the corresponding DIO#.FILTER can be set to adjust the filter of the input value.
