The statistics function can be used to record any variable. Please see the notes at the end of this article.

Call menu Project settings - Statistics

To add variables, drag them from Variables window to the left pane. Double-click on the variable to switch to the detailed settings:

Max. Data sets recording	The maximum number of data records is set here. If this number is exceeded, the oldest data records are overwritten with the newest ones.
Name	Alias Name
Only write commands	Only telegrams with write command are recorded and no acknowledgements.
Line color	Line color
Line Typ	Linear: The data points are connected via a straight line, this is intended for recording analog values. Rectangle: The data points are connected via a rectangle, this is intended for recording bit values.
Minimum / Maximum	Minimum / maximum for the display. With these parameters the display can be limited to limit faulty values. This setting has no effect on the recording, if minimum and maximum are equal, the limitation is not active.
Trigger	Telegram: Recording at each telegram (see Diagnostic Events). Change: recording when the value is changed. Time: Cyclic recording after a specified time. Time+change: Cyclic recording after a certain time but only if the value has changed.
Time type	This parameter defines a trigger when the variable is recorded: Telegram: For each telegram Change: When changing the value Time: At a specific time Time + change: When the value changes and when the time has been exceeded.
Time seconds	Only visible at time type "Free"
Difference	Only visible at time type "'Change"

When the runtime is started, a telegram is always recorded regardless of the settings. The physical address is 0.0.0 and the service ID is that of the statistics process.
The controller has a Micro SD card as memory. Generally only a limited amount of data can be written to flash memory because the flash wears out over time. Therefore, appropriate filters should be set for the recording so that not too much data is recorded.
For the standard SD card, it is recommended to record no more than 20,000 data sets per month on a permanent basis. More data can be recorded in the short term for diagnostics.
How many records are recorded can be determined by recording a certain time and then connecting to the controller. The number of records is displayed in the title bar.
If more data is to be recorded, the controller can be optionally equipped with an industrial memory card, with this option there are no limitations on the data sets and an extended warranty on the data drive.
