7.4.6 Index logging once a month
This type of datalogging is used to log the index value for each input once a month. The time and day
(from 1 to 28) logging is carried out may be set with a parameter.
The parameters to be used, are the following :
• Time of measurement (datalogging once a week, or once a month) (parameter 0x83)
• Day of the week, or of the month (datalogging once a week, or once a month) (parameter 0x82)
These parameters must by initialized before activating the datalogging mode.
The format of the applicatives commands for reading and writing internal parameters, is described
in chapter 6.2.
➢ Time of measurement (datalogging once a week, or once a month) (parameter 0x83)
This parameter allows to synchronize the periodic measurement. It is expressed in multiples of hour, and its
value must set from 0 to 23.
➢ Day of the week, or of the month (datalogging once a week, or once a month) (parameter 0x82)
Here, the format is different from the datalogging once a week. Indeed, the day of measurement is set from
0 to 28. And, the system does not manage changes in the number of days in a month.
Example : a user wants to log the temperature the 5
th
day of the month, at 12:00.
• Time of measurement (datalogging once a week, or once a month) (0x83) = 0x0C
• Day of the week, or of the month (0x82) = 0x05
• bits [b3:b2] of 'Operating Mode' byte (0x01) set to '11'
