7.5.2 Parameter setting of the Advanced Datalogging mode
To activate the advanced datalogging, the user have to follow the following steps :
Configure the index logging in time steps (see chapter 7.4.4);
Choose the measurement period;
Select the start time of the first measurement ;
Select the precision level (only for the PT100, PT1000 sensors).
When the datalogging mode in time steps is enabled, the system only logs the memorised index
values as soon as the preset time is attained; and this until the datalogging mode is disabled.
7.5.3 Principle of reading the temperature, and re-initializing the storage table
The concept of reading the logged values of the advanced datalogging is to interrogate periodically the
module with a long period of time, so that the consumption won't be penalized by too frequent readings.
The advised method is to read periodically the stored values, then to re-initialize the advanced datalogging in
order to flush the old values.
The reading radio command uses the
Multi-frame
mode of the Wavenis protocol (except in repeater mode).
The use of this command is describes in the WaveCard application handbook.
The re-initialization of the storage table is accomplished by stopping, then by re-starting the
datalogging mode through the Operating Mode byte.
The synoptic of the following page presents the principle to be applied.
