Syntax:  | 
#CONTOUR LOOKAHEAD LOG [ON | OFF | CLEAR] [ [ PARAM=.. ] ]  | 
ON  | Activate logging of contour elements by the NC command.  | 
OFF  | Deactivate logging of contour elements by the NC command.  | 
CLEAR  | The logging buffer is cleared at every program start. Use this NC command if the buffer needs to be cleared while the program is running to log a new area. Every time the buffer is cleared, decoding and execution are synchronised by an implicit #FLUSH&WAIT. Clearing can be executed while logging is active or inactive.  | 
PARAM=..  | This parameter allows the user to add an user-defined additional parameter (8 byte floating value) in the log entry.  | 
![]()  | If #CONTOUR LOOKAHEAD LOG ON is detected several times while a program is running, only the first marked area is provided. The command #CONTOUR LOOKAHEAD LOG CLEAR can be used to delete the last marked area. The next area is then supplied again with #CONTOUR LOOKAHEAD LOG ON.  |
