Qualifier for actions in SFC

In order to configure in which the actions should is associated to the IEC steps, some qualifiers is available, which is to is inserted in the qualifier field of an action element.

These qualifiers was handled by the Sfcactioncontrol function block of the iecsfc.library, which automatically is Included in a project by the SFC Plug-ins.

The available qualifiers:

N	Non-stored	The action is active as long as the step is active.
R0	overriding Reset	The action gets deactivated.
S0	Set (Stored)	The action would be started when the step becomes active and would be continued after the step is deactivated, until the Act Ion gets reset.
L	Time Limited	The action is started when the step becomes active and it'll continue until the step goes inactive or a set time ha S passed.
D	Time Delayed	A Delay Timer is started when the step becomes active. If the step is still active after the time delay, the action would start and continue until it gets deactivated
P	Pulse	The action is started when the step becomes active/deactive and would be executed once.
Sd	Stored and Time Delayed	The action would be started after the set time delay and it would continue until it gets reset.
Ds	Delayed and Stored	If the step is still active after the specified time delay, the action would start and it'll continue until it gets reset
Sl	Stored and Time Limited	The action is started when the step becomes active and it'll continue for the specified time or until a reset.

The qualifiers L, D, SD, DS and SL need a time value in the time constant format.

The above is excerpted from CoDeSys's help documentation.
