Guide on how you can set points to history recording and create history groups in FX-Editor
To set history recording to points go to "Points" page in FX-Editor.
Then select the point you want to have history recording. and go to edit the point.
Then select "History point" from the points settings.
Now you will see the history settings for the point.
In the field "Samples max." you can choose how many samples from the point will be saved. Once the maximum amount of samples is reached the oldest values will be erased when saving new values. Maximum amount of samples for each point can be 20 000.
In the field "Sample time" you can choose the interval of saving the points value as a sample. Write in the field the number and choose from the dropdown menu whether the value is in seconds, minutes, hours or days.
The value in "Days max." field is calculated and is dependent on the Samples max. and Sample time values. This will tell you how long back the history of the point can be viewed with current settings.
With the value in "Tolerance" field, you can set a minimum value change for saving a sample. This can extend the length of the history as not all samples are saved, if the value has not changed enough.
Once you have set the desired settings for history saving. Click the "OK" button.
Next go to "History" page in FX-Editor.
You will see in the list of "History points" the points that have the history settings active.
