EPI23xx-xxxx, ERI23xx-xxxx - Input debouncing and input signal extension
The digital IO-Link box modules EPI23xx and ERI23xx support a configurable input debouncing and a variable input signal extension for all digital inputs. This can be set via Device Parameter Object 0x0800. The set value applies for all digital inputs. How to set the parameters of the IO-Link Device will be explained in the section EPI2xxx, ERI2xxx - set up the parameters of IO-Link Device.
Input filter: variable adjustable over Device Parameter (Object 0x0800 Subindex 1).
Value | Filtertime [ms] |
|---|---|
0 | 0 |
1 | 0.5 |
2 | 3 |
3 | 10 |
4 | 20 |
The value decides the delay with which the input value is transferred to the higher-level control. Impulses that are smaller than the filter time will be ignored. In the figure below function examples are presented with a filter time of 10 ms.
Input signal extension time: variable adjustable over Device Parameter (Object 0x0800 Subindex 2).
Value | Input signal extension time [ms] |
|---|---|
0 | 0 |
1 | 0.5 |
2 | 3 |
3 | 10 |
4 | 20 |
5 | 50 |
6 | 100 |
The parameter specifies the time for which an input impulse is extended with additional momentum change. Short change of the input impulse during the signal extension will be ignored.
If the input debouncing and the input signal extension is active, the input impulse is always filtered first and then extend the result.
