LOGS CONFIGURATION
The last page of the configuration is about logging. If data logging is not desired, you should disable it.
Logs configuration should be carried through initially by choosing the start mode and stop mode for the logging process.
If, on the previous screen, the start and/or stop of the loggings were assigned to one or two alarms or events, this option
is sealed and cannot be changed on the Logs screen.
If you want to use the start and/or stop of the loggings through Modbus commands, you must enable these options. In
addition, you must select which is the memory where the logging data must be stored: in the internal flash (512k logs) or
in the SD card inserted by the user.
Finally, you must select which channels you want to log and what is the desired log rate. The channels can be selected
for logging moving them from the left side column (available channels) to the right side column (channels to be logged).
A maximum of 100 channels can be logged, but keep in mind that the more channels to be logged, the slower is the
logging rate that can be used.
The logging rate is given as a logging interval and it is common to all channels. In other words, a rate of 1 second means
that all channels selected for registration will be logged once per second. Although the equipment allows for a rate of up
to 1000 logs per second, you must bear in mind the following side effects, as they are described below:
• It is not good to have a logging rate faster than the reading scan of the analog channels or than the reading scan
of the remote channels. In such a case, the logs would have repeated data.
• The more logs we have in memory, the slower the download process will be and more data will be processed in
preview and export.
