edouard@3840: 
edouard@3840: N : non-stored - The action code body is executed or the Boolean variable is set as
edouard@3840: long as the step is active.
edouard@3840: 
edouard@3840: R : overriding reset &#8211; When the step has previously been executed with the S
edouard@3840: (including DS, DS, and SL) qualifier, the R qualifier will stop the execution of the
edouard@3840: code or reset the Boolean variable.
edouard@3840: 
edouard@3840: S : set (stored) - The action code body is executed or the Boolean variable is set.
edouard@3840: This state is stored as soon as the step becomes active. It can only be reset
edouard@3840: explicitly by associating the same action to a different step using the qualifier 'R'.
edouard@3840: 
edouard@3840: L : time limited - The action code body is executed or the Boolean variable is set as
edouard@3840: long as the step is active but maximal for the fixed time interval.
edouard@3840: 
edouard@3840: D : time delayed - The action code body is executed or the Boolean variable is set
edouard@3840: after the fixed delay time has elapsed. The action remains active as long as the step
edouard@3840: is active. If the step is active shorter than the fixed delay time the action does not
edouard@3840: become active.
edouard@3840: 
edouard@3840: P : pulse - As soon as the step is active the action code body is executed or the
edouard@3840: Boolean variable is set for one operating cycle. (Note: The code body will then
edouard@3840: execute for one additional operating cycle with the Step.X variable FALSE.)
edouard@3840: 
edouard@3840: SD : stored and time delayed - the action code body is executed or the Boolean
edouard@3840: variable is stored and set when the fixed delay time has elapsed after the step
edouard@3840: activation, even if the step becomes inactive. The action remains active until it is
edouard@3840: reset. If the step is active shorter than the fixed delay time the action becomes active
edouard@3840: anyway.
edouard@3840: 
edouard@3840: DS : delayed and stored - The action code body is executed or the Boolean variable
edouard@3840: is set when the fixed delay time has elapsed after the step activation. The action
edouard@3840: remains active until it is reset. If the step is active shorter than the fixed delay time
edouard@3840: the action does not become active.
edouard@3840: 
edouard@3840: SL : stored and time limited - The action code body is executed or the Boolean
edouard@3840: variable is set and stored for a fixed time interval as soon as the step is active. If the
edouard@3840: step is active shorter than the time interval the action is active for the whole time
edouard@3840: interval anyway. If the action is reset during the time interval the action becomes
edouard@3840: inactive as soon as the action is reset.

edouard@3840: Basically it shows following features of Beremiz:
edouard@3840: - web interface (SCADA) using integrated web server in SVGHMI extension;
edouard@3840: - interaction with web UI;
edouard@3840: - functional blocks in SFC language.
edouard@3840: 
edouard@3840: 
edouard@3840: 
edouard@3840: 
edouard@3840: SVGHMI is extensions to build web interface to PLC. It has *integrated* web-server. So it's NOT necessary to install Apache, lighttpd or nginx for that!!!
edouard@3840: 
edouard@3840: As the program is running in PLC, web UI will be available at http://localhost:8009/.
edouard@3840: 
edouard@3840: Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: SVGHMI extension. 
edouard@3840: Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately.
