Hello all, I would like to sign my boot application for my Raspberry PI. I generated the X509 Certificate and loaded it to the raspberry. It is successfully displayed as trusted certificate. However, I cannot download and start the Application to the Rasperry, due to a signature mismatch.The error message is rather clear, but I still don’t see how I can fix the issue, since the certificates on the Controller seem to mach the certificate in the user profile. Could you tell me where the error is or which step I am missing. Many thanks and kind regards Andreas

Raspberry Pi 4 Codesys 3.5.20 sp3 Codesyscontrol 4.15.0.0 based on sdk 3.5.21.0 Hi all, I have found a lot of topics but none of them get me on the right path, therfore i started a new post. Usually i work with plc based systems and codesys but now im trying to create an project where i read out a serial data stream from an arduino connected by an USB port. in the future this need to be more arduino's but first trying to make it work with one I had my program working but i needed to update my raspberry pu to the letest version to get the mimo screen working. Now i tried several rules in the CODESYSControl.cfg and/or CODESYSControl_User.cfg files but i never get the com port opened. At this moment i have an file CODESYSControl_User.cfg with entry: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 I tested the connection with minicom and the data runs fluently. Can somebody help me with what could be wrong? the com port states ERROR_UNKNOWN 5004 when i tried to open.

Post by yuan on Seeking a Code-Based Solution for EtherCAT Slave Dropout or Master Errors in Production (Beyond Software Hot Reset) ^{CODESYS Forge talk (Post)}
I need official assistance with the following issue: During EtherCAT communication, if a slave station drops off the network or the master station encounters an error, the problem can currently only be resolved by performing a software-based hot reset. In actual production environments, this approach is unacceptable. Is there a method to resolve these issues programmatically, through code?

Post by jami on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Hello, i am trying to read multiple lines from csv file with caa file library and oscat. I have wrote 7 lines in the csv with separation '$R$L'. In my "extracting values" part I check line feeds and chars. After that I convert my buffer to string with oscat but I'm only able to read the first line from the csv. No matter if I even change start position where I start converting the buffer, I only get the first line. Here's my code for the reading and extracting value parts: 4: (*Reading the file*) fileread.hFile := filehandle; fileread.pBuffer := ADR(buffer); filesize1:=SIZEOF (buffer); fileread.szbuffer:=filesize1; fileread.udiTimeOut := 100000; fileread(xExecute := TRUE); IF fileRead.xDone THEN iFilesize:=TO_INT(fileread.szSize); writestate:=3; fileRead.xExecute := FALSE; END_IF 5: (*Extracting values*) //here i check the number of line feeds and chars. It works WHILE i < ifilesize DO c:=buffer[i]; IF c= 10 THEN IF lineindex<=99 THEN lineIndex := lineIndex + 1; END_IF ELSIF c <> 13 THEN IF charIndex <= 1000 THEN charIndex := charIndex + 1; END_IF END_IF i := i + 1; END_WHILE // Here i convert the buffer to string and transfer it to filelines:ARRAY[0..99] of string[254]. trig(CLK:=BUTTON); IF trig.Q THEN fileLines[i2]:=oscat_basic.BUFFER_TO_STRING(PT:=ADR(buffer), Size:=TO_UINT(fileread.szBuffer), start:=TO_UINT(bufferStart), stop:=TO_UINT(filesize1)); i2:=i2+1; bufferstart:=bufferstart+80; END_IF If anyone has idea how to read multiple lines, it would be nice. Even if you have example codes that work, that would help a lot.

Post by christoph--b on Probleme mit Speicheraufteilung nach Wechsel von Wago 750-841 zu 750-891 ^{CODESYS Forge talk (Post)}
Hallo, ich habe in meiner Hausautomation eine Wago 750-841 mit einem doch mittlerweile umfangreichen Programm. Diese wollte ich nun gegen eine 750-891 der 4. Generation austauschen. Aufgrund der Programmgröße hatte ich damals die Speichergröße für Retainvariablen von 16#4000 auf 16#7000 vergrößert und so läuft sie nun seit Jahren fehlerfrei. Allerdings mit der 750-891 bekomme ich offensichtlich eine Überschneidung mit dem Modbusregister, denn die Werte über Modbus spielen verrückt. In der Standardgröße mit 16#4000 tritt das Phänomen nicht auf, reicht dann aber nicht für das vorhandene Programm. Dafür gibt es sicher eine Lösung, denn die 891 hat ja deutlich mehr Speicher. Allerdings kenne ich mich mit der Speicheraufteilung nicht aus, wo man da was optimieren kann, damit ich den Speicherbereich entsprechend erweitern kann, aber es zu keiner Überschneidung kommt. Für Hilfe wäre ich sehr dankbar

Problem gelöst: die Größe von Memory habe ich reduziert und die Basis vom Retain Bereich entsprechend nach unten verlegt. Dann konnte ich die Größe vom Retain Bereich um den Betrag vergrößern. Jetzt läuft alles wie es soll.

Post by joerg-schneider on SVN: "Include externals" Fehlermeldung ^{CODESYS Forge talk (Post)}
Ich habe eine Bibliothek unter Subversion verwaltet und verwende Teile davon in anderen Subversion Projekten mit "Include externals". Wenn man die Bibliothek mit "Copy (Branch/Tag)" kopiert, lässt sich die Kopie nicht mehr mit "Include externals" in anderen Projekten einbinden. Es kommt eine Fehlermeldung, dass ein Pfad nicht gefunden wurde (siehe Anhang). Auch wenn man das Bibliotheksprojekt direkt auf dem SVN Server kopiert (mit Tortoise SVN), kommt die gleiche Fehlermeldung beim Versuch die Kopie mit "Include externals" in anderen Projekten einzubinden. Ich nutze Codesys 3.5.20.60 mit Codesys SVN 4.6.2.0. Wie kann man Projekte auf dem SVN Server so kopieren/verschieben, dass sie später mit "Include externals" in anderen Projekten verwendet werden können?

Read Global Variable from an IoT Device
Last updated: 2025-07-22

Post by fedex03 on Read Global Variable from an IoT Device ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to the forum, and to programming with CodeSys. I am dealing with IoT device for industry and I should check if a device is able to read/write global variables in an EtherNet/IP Master. Since I do not have an EtherNet/IP PLC, I thought of using CodeSys as a softPLC. I created a program with a set of global variables (GVL) and a task that increments them. I would like to know if I need to enable any options so that the global variables can be read by IoT devices. My device supports Class 2 Class (Explicit Messaging Connection) communication. Thank you in advance for your help.

Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Dear @gseidel, @tk096, I noticed that with SoftMotion V4.18.0.0, if a new axis is added to the project, the ramp type selection defaults to "Quadratic". In all previous versions, the velocity ramp type selection was "Trapezoidal". This causes some unexpected issues in projects with SoftMotion version V4.18.0.0 for newly created or newly added axes to existing projects. Is it possible to reconsider this situation in the next update and set the velocity ramp type to "Trapezoid" by default again? Best Regards, Imdat

Post by timvh on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
If you want to use the Test Manager, I prefer to start all the tests through the scripts of this manager. So open from there the projects, load it and run it. If you also want to use Python scripts to access CODESYS functionality, while executing a Test Manager script, then also start them from the Test Manager commands.
