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.
