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

+
+Basically it shows following features of Beremiz:
+- web interface (SCADA) using integrated web server in svgui extension;
+- interaction with web UI;
+- functional blocks in SFC language.
+
+
+
+
+SVGUI 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!!!
+
+As the program is running in PLC, web UI will be available at http://localhost:8009/.
+
+Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: svgui extension.
+Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately.
