The solution recommended by Coronis Systems to counter reduction of the operating life in the case of a
high module population is to use the polling mode which offers the advantage of transmitting only one frame
to read a group of modules.
The yellow line below indicates the approximate operating life for a population of 50 modules by polling them
in groups of 25 modules. (YELLOW)
1.3.3 INFLUENCE OF DATALOGGING MODE MEASUREMENT PERIOD
As a reminder, the internal memory of a standard WaveTherm module may save up to 48 temperature
readings.
The graph below illustrates the reduction in product operating life according to the datalogging mode
measurement period.
