TcMarkOption

The constants in this global variable list define the possible marker types (see Marker type). In addition to the marker types, the option RefToCaller is defined, which enables the task references to be displayed in the TwinCAT 3 Realtime Monitor. If this option is activated it must be ORed with the desired marker type.

Sample:

fbLogMark.LogMarkEx(markCounter, TcMarkOption.Start OR TcMarkOption.RefToCaller);

The sample shows the setting of a marker, "markCounter", with the marker type "Start" and the option "RefToCaller".
