Processor
Controls all functionalities after wake-up: First, the values of all measurement inputs are
sampled. After that, RF signal transmission is triggered if one or more of the following con-
ditions are met:
a)
One of the input values has changed since the last radio transmission (one of the 4
digital inputs has changed or one of the 3 analog inputs has changed equal to or
more than a defined value of the total measurement range), or
b)
Counter for redundant retransmission is elapsed
c)
The wake-up has been triggered via the WAKE pins
After every RF transmission, all measurement values are stored for data comparison at
next wake-up time.
See chapter 2.5 for configuration of timing of redundant retransmission.
RF transmitter
The radio transmitter is powered up by the processor when the sending condition is posi-
tive. The output LED is activated temporarily during telegram transmission.
