Each step is displayed with the same length, regarded of its contents.
Step identifiers are displayed for the program which currently has the
focus. Status: "Program data was modified" is not displayed in the
Program screen of channel 1.
Steps are displayed in proportion to the duration of their execution
time. With wait markers, the step length is displayed proportional to
the wait time.
Time computation must have been performed by execution of the
workpiece program. If the time computation was not performed,
standardized view is displayed. Programs which were modified after
the time computation are marked with "Data modified". Computing the
time again sets all programs to "Data updated". See below.
Preparatory phase: Message: Time computation is initialized. Please
wait....
Initiation of execution: Message: Time computation is active.
