There are 4,650 data points available for each
parameter. When a longer recording is made, the
oldest data are continuously overwritten.
There are 3 types of recordings:
–
Recording interval long: Allows data to be
tracked over several days.
–
Recording interval short: Allows more exact data
to be tracked over several hours.
–
Recording in the event of a change (COV): Only
makes a recording when the parameter changes,
allowing recordings to be made over an extended
period.
The short and long recording intervals can be set by
means of the corresponding parameter settings on
the ‘Save/load’ page.
The trends cannot be displayed on the HMI. They
must be copied onto a USB stick to display them on a
computer. The trends are saved as a csv file.
