NOTE It is possible for “hysteresis BandHigh” to exceed the maximum possible “inputValue” in cases where “inputValue” is large and hysteresis is increased. Software developers can choose to limit “hysteresis BandHigh” to the maximum possible “inputValue’ . Figure 2 shows an example of “inputValue”changes, together with the resultant hysteresis bands (vertical lines) for the case where “hysteresis” is 10 % and“hysteresisMin” is 50. At measurements 1, 2, 4, 5, 6, 8 and 10, the illuminance level event is generated due to the new “inputValue”being outside of the previously calculated range of [“hysteresis BandLow”, “hysteresis BandHigh”]. Measurements 3, 7 and 9 do not generate the iluminance level event ， because the “ inputValue”is inside the previously calculated range of [‘ hysteresis BandLow, “hysteresis BandHigh”]. The initial values for “hysteresis BandLow” and“hysteresisBandHigh” are 0 due to power up of the device.
9.5 Configuring the input device
9.5.1 Using the report timer
If the report timer is set, it shall generate a ‘repeat’ trigger every Treport even if the “input Value” has not changed. The report timer shall be restarted every time an event is sent.
If multiple devices have the report timer enabled, they might send out conflicting data intended to affect the same control gear. Depending on the application, care needs to be taken when enabling the report timer.
9.5.2 Using the deadtime timer
If the deadtime timer is set, the instance shall not send out an event until the deadtime timer has expired. The deadtime timer shall be restarted every time an event is sent.
9.5.3 Setting the timers
The event report timer shall be programmable as is indicated in Table 3.
For each timer, a fixed minimum duration and a fixed increment in duration are given. The application controller can set the desired actual timer duration by setting the number of increments to a value in the range [0,255]. The resulting time shall be strictly monotonic according to the following formula:
Time = Tincr * multiplier
Only on (re-)starting a timer the actual time shall be calculated based on the corresponding variable. This implies that the times only change after any running timer has been cancelled or expired. The tolerance on the time shall be ±5 %.AS NZS 62386.304 pdf download.
