9.17 Hour log register block
Generally the Modbus master application can select the relevant
log series and the relevant number of hours back in time.
Typically several communication sessions (request telegrams)
are needed to read the data.
The communication interface ensures that logged data is
protected against internal update during the time it is accessed
from Modbus, so that the Hour log constitutes a time-consistent
block (data coherency). Every time the real-time clock increments
by one hour, all the logged data in the hour log is shifted one hour
back in time (and the oldest data set is cleared). The exact time
where this happens will be delayed a few seconds relative to the
hour incrementation, so to be sure to read hour log data that has
been correctly updated, we recommend reading data at least 30
seconds after the hour incrementation.
