Example as pseudo code:
Input value = QUERY_INPUT_VALUE ()
Variable = input value × 4
Input value = QUERY_INPUT_VALUE_LATCH ()
Variable = va input value ÷ 64

Evaluating events
An event of an absolute input device can be triggered cyclically or at a certain change of the
value. Depending on the type of sensor used, the following steps are necessary to display the
obtained value:
Temperature sensor with a positive temperature range:
Setting in memory bank 3: sensor type = [0x00], [0x01] or [0x02]
Setting in memory bank 3: range = [0x00]
Temperature measurement value [°C] = event info/10
Temperature sensor with a negative temperature range:
Setting in memory bank 3: sensor type = [0x00], [0x01] or [0x02]
Setting in memory bank 3: range = [0x01]
Temperature measurement value [°C] = (event info – 250) / 10
Variable resistor:
Setting in memory bank 3: sensor type = [0x03]
Measurement value [
Ω
] = event info x 100
