Digital input (0x82199)
The binary input signal is output via the process data in index 0x60n0:01 "Input".
The digital input module provides a parameterizable filter time. This can be used to suppress interference, such as bouncing of a switch signal. Signals with a pulse duration shorter than the set filter time are suppressed.
Filter function sequence
- The filter is enabled on delivery, index 0x80n0:02 "Enable filter" = TRUE
- The filter is parameterized via index 0x8n0:11 "Filter time". Available filter times:
Index 0x80n0:11 "Filter time" | Meaning |
|---|---|
100dec: 100 µs | Signals < 100 µs are suppressed |
500dec: 500 µs | Signals < 500 µs are suppressed |
3000dec: 3 ms | Signals < 3 ms are suppressed (default) |
10000dec: 10 ms | Signals < 10 ms are suppressed |
20000dec: 20 ms | Signals < 20 ms are suppressed |
- The filter is disabled by setting index 0x80n0:02 "Enable filter" = FALSE. In this case, the input signal is only filtered via the hardware. The filter value here is typically 10 µs.
