causes the step indicated to be executed after the current step. The next step can skip
or repeat other steps as necessary. Pause Step determines at which step the sequence

SFC (Sequential Function Chart) Display
The SFC (Sequential Function Chart) Display, Figure 36, supports runtime
monitoring and manipulation of an individual sequence by presenting information,
similar to that found in the Sequence Detail Display, but with a graphical flow chart
format. This chart presents TCL steps and activities (actions a sequence will
execute), along with the transition conditions which determine the flow of the
sequence execution. Activities and conditions describe the program flow in plain
language rather than the TCL syntax used in the Sequence Debug Display.
