Post by caprez95 on Deleting the trend recording history ^{CODESYS Forge talk (Post)}
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by rk-gaw on Unhandled exception and refactoring error ^{CODESYS Forge talk (Post)}
Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.

Post by kreisfilho on Stop raspberry from executing a plc program ^{CODESYS Forge talk (Post)}
Hi guys, Can someone inform where in a raspberry pi are stored the codesys programs? I´ve been training the use of a RPI as PLC, which works pretty well, however while both the RPI and PC (running codesys) remain connected to the same network. The question is: how to run the codesys program downloaded to the RPI as a stand alone device (disconnected from the PC)? Thanks! Kreis
