    Is there a way to work around the error that happens when trying to set a reference to 0 after it isn't needed or is invalid? Trying to do this in codesys >= V3.5.15 results in an error. See example below. Now I could great a GVL with a bunch of unset references, but I'd end up with a large amount of null types. METHOD FB_init : BOOL VAR_INPUT bInitRetains : BOOL; // if TRUE, the retain variables are initialized (warm start / cold start) bInCopyCode : BOOL; // if TRUE, the instance afterwards gets...

    Für das, brauchen Sie das CODESYS Automation Server Connector. https://store.codesys.com/codesys-automation-server-connector.html Installieren Sie das .package, und CODESYS IDE neustarten.

    Zitat aus der Onlinehilfe: "Klicken Sie in CODESYS im Infobereich der Taskleiste auf das Gateway-Symbol und wählen Sie im Menü den Befehl Allow Edge Gateway Configuration." Genau dieses Symbol kann ich nicht finden, obwohl ich das Edge Gateway im Store heruntergeladen und installiert habe.

    Der Tipp von i-campbell war goldrichtig! Das nochmalige Setzen von rs485 (trotz der bestehenden rs485 Rückmeldung) war erfolgreich. @eschwellinger: Kann man die Wago FW16 mit Codesys 3.5.16.0 bedenkenlos verwenden? Oder sollte man besser noch abwarten? Gruß annD

    i added the following lines to the while loop of the iteration, like you posted above: IF pClientData^.GlobalData.ClientType=Visu_Clienttype.WebVisualization THEN timLastWebVisuUsage:=pClientData^.GlobalData.LastUsage; END_IF and out of the while this code: xRemotePanelUsage:= timLastWebVisuUsage>timLastWebVisuUsageOld; timLastWebVisuUsageOld:=timLastWebVisuUsage; tofRemotePanelUsage(IN:= xRemotePanelUsage, PT:=T#300MS); That's my solution, I don't know how to do it with the methods.

    The actual problem could be in here: 42: // New file created - Write header //Creation of table header string sData := ''; FOR j := 0 TO SIZEOF(HeaderNames) DO sData := CONCAT(sData, HeaderNames[j]); sData := CONCAT(sData, ';'); END_FOR filwr.hFile := hFile; filwr.pBuffer := ADR(sTestString); szFileSize1:= SIZEOF(sTestString); filwr.szSize := szFileSize1; filwr.udiTimeOut := 100000; // 100ms TimeOut filwr (xExecute := TRUE); IF filwr.xDone THEN ManagerState := 42; filwr (xExecute := FALSE); END_IF...

    [Snippet of code in first response which throws the error] Hi, I'm creating a program for a machine that should test our products. The testing sequence is complete but I am unable to log the data. I'm able to create a folder and a file to write to. But I'm unable to write to the file. The filwr FB gives me an error on eError of value 1. At the moment I'm at a loss, any help would be appreciated.

    Hi, I fixed the problem by deleting the administrator rights (tricky to do) and now I didn't need to do any additional "trusted" certificates. LZ
