ModuleGroup | "Digital Input" (0x82199)
A module for four digital inputs is available in the "Digital Input" ModuleGroup.
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.
The process data and setting objects depend on the configuration. The available process data and settings objects are shown below depending on the configuration.
