If several steps are active in a parallel branch, then the active step whose action will
be processed next is displayed in red.
If IEC steps have been used, then all active actions in Online mode will be displayed in
blue.
With the command 'Online' 'Step over' it is stepped always to the next step which
action is executed. If the current location is:
• a step in the linear processing of a POU or a step in the rightmost parallel branch
of a POU, execution returns from the SFC POU to the caller. If the POU is the main
program, the next cycle begins.
• a step in a parallel branch other than the rightmost, execution jumps to the active
step in the next parallel branch.
• the last breakpoint location within a 3S action, execution jumps to the caller of the
SFC.
• the last breakpoint location within an IEC action, execution jumps to the caller of
the SFC.
• the last breakpoint position within an input action or output action, execution
jumps to the next active step.
With 'Online' 'Step in' even actions can be stepped into. If an input, output or IEC
action is to be jumped into, a breakpoint must be set there. Within the actions, all the
debugging functionality of the corresponding editor is available to the user.
