Dialog Box ‘Advanced Trend Settings’

Function: This dialog box provides more settings for configuring trend recording.

Call: Click Advanced in the editor of a TrendRecording object.

Measure in every n-th cycle

Frequency that the runtime system records data, depending on the number of processed task cycles. Select a value from the drop-down list or type a value into the input field.

Using the settings from the task configuration, CODESYS calculates the time interval according to the frequency. Therefore, the calculation is possible only if at least the task cycle time is set. The result is shown on the right of the input field in normal syntax (for example, 1h1m1s1ms).

Default: 1 means that data is recorded in each task cycle.
Additional Runtime Buffer for

Length of the time interval when the runtime system can record more data (for example, 1000 ms).

If a delay occurs when writing data in the runtime system component, then there is a risk of data loss due to overwriting. In this case, the runtime system uses the addition buffer.
