Digital input alarm

The product integrates a digital input with a terminal block to connect a sensor and detect state changes. The digital input only works on event

*Debounce time: is the minimum period for an event to be taken into account. For example if this period is 10 ms, all the impulse (high or low) smaller than 10
ms will not be taken into account. It avoids detection of rebounds during change of state.
In this example:
• Digital input is activated with high state detection longer than 100ms (register S382).
• The device send a frame after the detection of 5 events respecting the criteria (register S383).
Example :
Register

• Digital input is activated with high state detection longer than 100ms (register S382).
• the device send a frame each time a event respecting the criteria. (register S383).
No
NOTE: it is possible to send a frame only when a number of event on the input is detected
(S383).
