2.1.6 Transmitting the Keep Alive frame

If the device does not have periodic data configured, and no threshold is exceeded, it may not transmit data for a long time. So, to be sure that
the device is working properly, it transmits a Keep Alive frame (0x30) according to a determined frequency (S300)
The parameters associated with this operating mode is the setting of the transmission period of the Keep Alive frame (register 300). The com-
plete list of registers can be found in paragraph 3.4.

2.1.7 Digital Input alarm(s)

The device incorporates two digital inputs, one through the connected button and one via the terminal block, both for detecting a change in up
and down state.
The device allows the sending of a frame following a change of state on one of its inputs according to the following diagram:

S382

* Debounce time: minimum time to take account of a change of state. For example, if this period is
10 ms all pulses (high or low level) whose duration is less than 10 ms will not be considered. This
technique avoids potential rebounds during a change of state.
In this example the device:
• The device has a debounce time of 100ms and the button press alarm is enabled (regis-
ter 380).
• The device sends a frame for each button press (register 381)
• The alarm via the terminal block is disabled (register 382)
