2.2.3 Transmission on event of digital input
The product allows the measurement and the transmission of the values of the sensors following an event on a digital input according to the
following diagram:
This triggering can be on the rising edge, falling edge or both. A configurable debounce is present on every digital input.
Input TOR1 is associated with channel A and input TOR2 with channel B.
The settings associated with this mode of operation are:
•
The transmission periodicity (zero in this usage situation) (register 301)
•
The presence and type of external sensor (registers 320 and 322).
•
The configuration of the events (registers 321 and 323).
A complete list of the registers can be found in paragraph 3.4.

The value of the high threshold of channel A is:
1 200 000x10=12 000 000nA so 12mA
The value of the hysteresis of the high threshold of channel
A is: 100 000x10=1 000 000nA so 1mA
The value of the low threshold of channel A is:
600 000x10=6 000 000nA so 6mA
The value of the hysteresis of the low threshold of channel
A is: 100 000x10=1 000 000nA soit 1mA
LThe value of the high threshold of channel B is:
8 000 000µV so 8V
The value of the hysteresis of the high threshold of channel
B is: 1 000 000µV so 1V
The value of the low threshold of channel B is: 3 000
000µV so 3V
The value of the hysteresis of the low threshold of channel
A is: 1 000 000µV so 1V
