Register Value encoding Value Result
S301 Decimal 0 Event mode
S320 Hexadecimal 0x02 Channel A configured for a sensor 4-20mA
S322 Hexadecimal 0x01 Channel B configured for a sensor 0-10V
S321 Hexadecimal 0x1C Channel A:
No threshold detection
Event detection on digital input on rising and falling
edges
• Waiting* period of 10ms
S323 Hexadecimal 0x18 Channel B:
No threshold detection
Event detection on digital input on rising edge only
• Waiting* period of 10ms
* Waiting* period (or debounce time): minimum time for taking into account a change of state. For example if this period is 10ms, all pulses
(high or low level) whose duration is less than 10ms will not be taken into account. This technique prevents rebounce on a change of state.
2.2.4 Transmission of a daily Keep Alive frame
In the event mode (threshold or digital), it is possible that the product would never send data frames. So to be sure that it is working properly a
Keep Alive frame is transmitted regularly according to the following diagram:
In periodic mode there is no Keep Alive frame transmission.
The settings associated with this mode of operation are:
• The setting of the period of transmission of the Keep Alive frame (once per hour to once per day) (register 300).
A complete list of the registers can be found in paragraph 3.4.
