Post by to-ke on Errors with VisuUserManagement library CODESYS Forge talk (Post)
Hallo zusammen, hi all, ich habe den gleichen Fehler. Auf einem Raspberry Pi geht der Fehler weg, wenn ich alles bereinige und dann vollständig übersetze. Wenn das Projekt im Codesys Development System wieder neu geladen wird ist der Fehler aber wieder da. Mit eine Win V3 x64 PLC kann ich den Fehler nur unterbinden wenn ich auf der HMI das VUM_Login einbinde. Dieses brauche ich aber nicht, da ich die HMI für das User Management selbst gestaltet habe. Das funktioniert auch. I have the same error. On a Raspberry Pi the error goes away if I clean everything and then compile completely. When the project is reloaded in the Codesys Development System, the error returns. With a Win V3 x64 PLC I can only prevent the error if I integrate the VUM_Login on the HMI. But I don't need this because I designed the HMI for user management myself. That works too. Anyone have an idea to fix this problem. Many thanks

Post by ph0010421 on How to create a stopwatch? CODESYS Forge talk (Post)
Do you need an 'hours-run' counter? And 1 second resolution is ok? I think you're over-thinking it. (The task time needs to be < 1second) Have a look at the LAD... Then, the time in seconds can be made into hh:mm:ss with this FUNction Declarations: FUNCTION funSecondsToStringTime: string VAR_INPUT InSeconds: UDINT; END_VAR VAR AsString: STRING; Minutes: UDINT; Hours: UDINT; Seconds: UDINT; MinutesAsString: STRING(2); HoursAsString: STRING(2); SecondsAsString: STRING(2); END_VAR and the code: Hours := InSeconds / 60 / 60; //Derive hours Minutes := (InSeconds - (Hours * 60 * 60)) / 60; //Derive minutes Seconds := InSeconds - ((Hours * 60 * 60) + (Minutes * 60));//Derive seconds HoursAsString := UDINT_TO_STRING(Hours); MinutesAsString := UDINT_TO_STRING(Minutes); SecondsAsString := UDINT_TO_STRING(Seconds); IF LEN(HoursAsString) = 1 THEN HoursAsString := CONCAT('0',HoursAsString); END_IF; IF LEN(MinutesAsString) = 1 THEN MinutesAsString := CONCAT('0',MinutesAsString); END_IF; IF LEN(SecondsAsString) = 1 THEN SecondsAsString := CONCAT('0',SecondsAsString); END_IF; AsString := CONCAT(HoursAsString, ':'); //assemble string AsString := CONCAT(AsString,MinutesAsString); AsString := CONCAT(AsString,':'); AsString := CONCAT(AsString, SecondsAsString); funSecondsToStringTime := AsString;

Post by dasch on Webvisu auf Iphones CODESYS Forge talk (Post)
Moin, ich arbeite an einer Visualisierung einer Fernbedienung, die auf mobilen Geräten laufen soll. Bei Iphones ist uns die Eigenheit aufgefallen, dass bei langem druck auf einen Button, die gesamte Seite markiert wird und dann kopiert werden kann. Manchmal popt auch die kleine Lupe auf, die einem helfen soll den Courser genauer zu platzieren. Weiß jemand ob man dieses Verhalten vielleicht durch zusätzliche Einträge in der webvisu.htm unterdrücken kann? Gruß, Daniel

Post by e60newbie on Alarmtabelle Historie CODESYS Forge talk (Post)
Hallo Forumsgemeinde, ich stehe vor einem Problemchen wo ich keine Lösung finde. Folgendes: wir haben ein HMI an einer Mobilen Arbeitsmaschine wo sämtliche Fehler in der SPS (nicht im HMI) resettiert werden und im HMI alle als "REP" definiert sind, also selbstresetierend wenn das "Auslösesignal" entfernt wird. Soweit so gut. Nun wenn der Kunde die Maschine mit einem Aktiven Alarm ausschaltet, auch das HMI, bleiben die Fehler in der Historie als aktiv hinterlegt. Es gibt hierzu keine möglichkeit diese zu Quittieren? Sieht eben etwas unschön aus wenn da Fehler als aktiv anzgezeigt werden die uralt sind.

Post by moritz-a on Datalogger Wago 8212 Speicherzugriff CODESYS Forge talk (Post)
Hallo, ich möchte einen Datenlogger schreiben für den Webdatenplotter der Wago. Ich habe jetzt das Problem dass der Baustein keinen Zugriff auf die Festplatte oder SD-Karte hat. In der Codesys kann ich über die Dateienansicht auch die Speicherkarte nicht sehen. Über FTP in Windows jedoch schon. Kann ich in der Webvisu vom Controller etwas ändern um daran zu kommen? orientiert habe ich mich an dem Anwendungshinweis von Wago und dem Video welche in E-Cockpit sind. Daten werden über Real normal geschrieben. Firmware ist die 26. Codesys ist die SP19 Patch 2.
