Description:
Digital input channels are sampled on a periodic basis. On NextMove, this is every millisecond. If an
input is active in hardware at the point of sampling, then that input is seen and processed according to
the rules of
INPUTMODE, INPUTACTIVELEVEL, INPUTPOSTRIGGER and INPUTNEGTRIGGER.
The
INPUTDEBOUNCE keyword specifies the number if samples an input must be active for in order to
be seen and then processed. This is useful in ‘noisy’ environments where false inputs can be seen and
where a contactor may ‘bounce’ as it changes state.
The default value is one, i.e. the input is not debounced. A value of two for example means that the
input must be present of two consecutive samples.
If debouncing is not on (set to 1), then the
IN and INSTATE keywords read the state of the inputs when
called. If debouncing is turned on (greater than 1), then the
IN and INSTATE keywords return the last
sample values.
The
INPUTDEBOUNCE keyword affects the current I/O bank as set with the BANK keyword.
Example
In order to avoid noise affecting the digital inputs, a valid input signal will have a minimum duration of
5 milliseconds. This equates to a debounce value of 6.
INPUTDEBOUNCE = 6
