|
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 – 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. |

|
1316 |
|
1317 Basically it shows following features of Beremiz: |
|
1318 - web interface (SCADA) using integrated web server in SVGHMI extension; |
|
1319 - interaction with web UI; |
|
1320 - functional blocks in SFC language. |
|
1321 |
|
1322 |
|
1323 |
|
1324 |
|
1325 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!!! |
|
1326 |
|
1327 As the program is running in PLC, web UI will be available at http://localhost:8009/. |
|
1328 |
|
1329 Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: SVGHMI extension. |
|
1330 Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately. |

|
1338 Back_id and sele_id inputs of these blocks are IDs of graphic primitives in SVG file. |
|
1339 This is the way how elements in SVG are bound to elements in PLC program. |
|
1340 You can find out or edit these IDs in Inkscape.]]></xhtml:p> |
