'Extras' 'Associate Action'
With this command actions and Boolean variables can be associated with IEC steps.
To the right of, and next to the IEC step, an additional divided box is attached, for the
association of an action. It is preset in the left field with the qualifier "N" and the
name "Action." Both presets can be changed. For this you can use the Input Assistant.
Maximum nine actions can be assigned to an IEC step.
New actions for IEC steps are created in the Object Organizer for an SFC POU with the
'Project' 'Add Action' command.
'Extras' 'Use IEC-Steps'
Symbol:
If this command is activated (denoted by a check in front of the menu item and a
printed symbol in the Tool bar), then IEC steps will be inserted instead of the
simplified steps upon insertion of step transitions and parallel branches.
If this option is switched on, the Init step is set as an IEC step when you create a new
SFC POU.
This settings are saved in the file "plcdesigner.ini" and are restored when »PLC
Designer« gets started again.
Sequential Function Chart in Online Mode
With the Sequential Function Chart editor in Online mode, the currently active steps
will be displayed in blue. If you have set it under 'Extras' 'Options', then the time
management is depicted next to the steps. Under the lower and upper bounds that
you have set, a third time indicator will appear from which you can read how long the
step has already been active.
In the picture above the step depicted has already been active 8 seconds and 410
milliseconds. The step must, however, be active for at least 7 minutes before the step
will be left.
With 'Online' 'Toggle Breakpoint' a breakpoint can be set on a step, or in an action at
the locations allowed by the language in use. Processing then stops prior to execution
of this step or before the location of the action in the program. Steps or program
locations where a breakpoint is set are marked in light blue.
