13 Trace Manager
A Trace makes it possible to record the value history of variables on the PLC — just like a digital sampling oscilloscope.
When the application is in runtime mode with trace, all statements are executed first within the task cycle. Then, data
recording starts with value storage including time stamps. These time stamps are relative and refer to the start time of the data
recording. The data yields a discrete time signal and
CODESYS displays its course in the trace editor.
