  1130 
       
  1131 N : non-stored - The action code body is executed or the Boolean variable is set as
       
  1132 long as the step is active.
       
  1133 
       
  1134 R : overriding reset &#8211; When the step has previously been executed with the S
       
  1135 (including DS, DS, and SL) qualifier, the R qualifier will stop the execution of the
       
  1136 code or reset the Boolean variable.
       
  1137 
       
  1138 S : set (stored) - The action code body is executed or the Boolean variable is set.
       
  1139 This state is stored as soon as the step becomes active. It can only be reset
       
  1140 explicitly by associating the same action to a different step using the qualifier 'R'.
       
  1141 
       
  1142 L : time limited - The action code body is executed or the Boolean variable is set as
       
  1143 long as the step is active but maximal for the fixed time interval.
       
  1144 
       
  1145 D : time delayed - The action code body is executed or the Boolean variable is set
       
  1146 after the fixed delay time has elapsed. The action remains active as long as the step
       
  1147 is active. If the step is active shorter than the fixed delay time the action does not
       
  1148 become active.
       
  1149 
       
  1150 P : pulse - As soon as the step is active the action code body is executed or the
       
  1151 Boolean variable is set for one operating cycle. (Note: The code body will then
       
  1152 execute for one additional operating cycle with the Step.X variable FALSE.)
       
  1153 
       
  1154 SD : stored and time delayed - the action code body is executed or the Boolean
       
  1155 variable is stored and set when the fixed delay time has elapsed after the step
       
  1156 activation, even if the step becomes inactive. The action remains active until it is
       
  1157 reset. If the step is active shorter than the fixed delay time the action becomes active
       
  1158 anyway.
       
  1159 
       
  1160 DS : delayed and stored - The action code body is executed or the Boolean variable
       
  1161 is set when the fixed delay time has elapsed after the step activation. The action
       
  1162 remains active until it is reset. If the step is active shorter than the fixed delay time
       
  1163 the action does not become active.
       
  1164 
       
  1165 SL : stored and time limited - The action code body is executed or the Boolean
       
  1166 variable is set and stored for a fixed time interval as soon as the step is active. If the
       
  1167 step is active shorter than the time interval the action is active for the whole time
       
  1168 interval anyway. If the action is reset during the time interval the action becomes
       
  1169 inactive as soon as the action is reset.

  1689 
       
  1690 Basically it shows following features of Beremiz:
       
  1691 - web interface (SCADA) using integrated web server in svgui extension;
       
  1692 - interaction with web UI;
       
  1693 - functional blocks in SFC language.
       
  1694 
       
  1695 
       
  1696 
       
  1697 
       
  1698 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!!!
       
  1699 
       
  1700 As the program is running in PLC, web UI will be available at http://localhost:8009/.
       
  1701 
       
  1702 Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: svgui extension. 
       
  1703 Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately.

  1711 Back_id and sele_id inputs of these blocks are IDs  of graphic primitives in SVG file.
       
  1712 This is the way how elements in SVG are bound to elements in PLC program.
