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 Pulse When the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated Width |

Usage
When DIO#.DIR = 0 (input) then the corresponding DIO#.FILTER can be set to adjust the filter of the input value.
Code
--> DI01.DIR 0 --> DIO1.FILTER 0 --> DIO1.FILTER 1
