Post by dkugler on EtherCAT Master: How many error frames till bus error ^{CODESYS Forge talk (Post)}
The story behind: I have had a EhterCAT fieldbus system where sometimes error frames occured. I noticed that the master is tolerant for some error frames, but if there are very much error frames the bus goes in error state. Does somebody know the limit of error frames above the bus changes to error state?

Post by gorditron on I2C Communication with ^{CODESYS Forge talk (Post)}
Hello, I have problems with the I2C communication to an ADS7828 AD converter. I don't get any value back from the chip. I use a Kontron chip (ARM 32SC) with Linux as the operating system.

I continue this topic by myself, I'm very happy with the Codesys support / community ;-) This information (Download time) should be stored in the compileinfo : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_load.html But the file is not text-readable (see attached file) so how to solve if download time is empty?

Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg

Post by timo on String nach erlaubten/unerlaubten Zeichen durchsuchen ^{CODESYS Forge talk (Post)}
Hallo, Ich bastele gerade an einer möglichst einfachen Möglichkeit mit der ich prüfen kann ob ein String Sonderzeichen enthält. Mein Ansatz ist ein ST FB mit einer Case Schrittkette. Ich vergleiche jedes Zeichen des Strings mit allen Zeichen eines vorher definierten Strings erlaubter Zeichen, der A-Z, a-z und 0-9 enthält und ggf angepasst werden kann, wenn ich weitere Zeichen erlaube. Leider wird meine j Zählervariable nicht richtig ausgeführt. Hat da jemand eine Idee? Oder gibt es eine einfachere Lösung/einen fertigen FB den ich mir anschauen kann? FUNCTION_BLOCK Sonderzeichen_Check VAR_INPUT inputString : STRING; // Zu prüfender String startCheck : BOOL; // Startsignal END_VAR VAR_OUTPUT ok : BOOL; // TRUE, wenn keine ungültigen Zeichen END_VAR VAR i : INT := 1; // Input-String Zähler j : INT := 1; // erlaubte Zeichen Zähler allowedChars: STRING := 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'; // Erlaubte Zeichen currentChar : STRING[1]; // Aktuelles Zeichen step : INT := 0; // Schritt END_VAR CASE step OF 0: // Warten auf Start IF startCheck THEN step := 10; END_IF 10: // Initialisierungen i := 1; j := 1; ok := TRUE; // Standard: ok step := 20; 20: // Durchgehen des Eingangs-Strings IF i <= LEN(inputString) THEN currentChar := MID(inputString, i, 1); // Aktuelles Zeichen step := 30; ELSE step := 70; // Alle Zeichen ok END_IF 30: // Durchgehen der erlaubten Zeichen IF j <= LEN(allowedChars) THEN step := 40; // Zu Schritt 40 ELSE step := 60; // Ungültiges Zeichen END_IF 40: // Vergleich IF currentChar = MID(allowedChars, j, 1) THEN i := i + 1; // Nächstes Zeichen im Input step := 20; ELSE j := j + 1; // Nächstes erlaubtes Zeichen step := 30; END_IF 60: // Ungültiges Zeichen ok := FALSE; // Setze auf FALSE step := 0; 70: // Alle Zeichen ok step := 0; END_CASE

Post by trusty-squire on Help with __SYSTEM.VAR_INFO ^{CODESYS Forge talk (Post)}
Not knowing exactly what you want to accomplish, you can try to use VAR_INPUT MyVar: POINTER TO BOOL; END_VAR MyVar contains the address of your referenced variable, and MyVar^ dereferences it allowing you to access the value. If this doesn't meet your needs, could you add more detail on what you are trying to accomplish?

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
Sounds feasible, but how would I create this object so that both applications would use the same instance of it. If this did work, it's still not really the solution I am looking for as it would mean mapping every variable I want to use on the hmi through this object vs I was hopping all the GVL variables would be available.

Post by cellohorst on File Creation Issue ^{CODESYS Forge talk (Post)}
Nope! The file path is $$PlcLogic$$ and NOT $$PLCLogic$$. Otherwise a new folder ('PLCLogic') is created (at least with a linux rt - like raspberry or compute module) with the new file in it if you open the file with eFileMode := FILE.MODE.MRDWR. That is a bad bug that I'll report right after this comment.

It would be great if there was a thread that had some quick-start links for basic how-to. But one that advanced programmers can jump into. I found this video playlist by SoftMotion-Black, which was very, very helpful: https://www.youtube.com/playlist?list=PLkc8m2OD0r9xJyfTiCBb1vuU_d2yBhjZ_ This person has some other great vids like creating your own custom library, which is awesome for OEMS.
