Post by ggarcia94 on CANOPEN SDO configuration ^{CODESYS Forge talk (Post)}
Hello, I´m connected to two drives via CANOPEN. The connection seems to be ok. However, I´m not able to get the PDOs to work even tho they are configured as in the manual of the drives. Looking at the SDOs I´ve seen that for each PDO there is a "Disable PDO" SDO that does not exist in the manual or in the EDS file of the drives. This "Disable PDO" signal has the same Index and Subindex as another SDO used to set and enable the COB-ID of the PDO. I´m assuming this is normal but why is Codesys creating a "Disable PDO" SDO for each PDO and could that be the reason the PDOs are not working?

Post by matthew on New Ladder Editor Issues ^{CODESYS Forge talk (Post)}
Hi There, When using the new ladder editor there is no option for function blocks to Remove uncalled FB call parameters. I also see no update function block. When you double click the function block it no longer opens the function block. I also now get warnings if I insert FB call without a contact in front. Warning is: (Impl)): C0373: Expression or part of it has no effect I take it the new editor must work differently? The only reason for using new ladder editor is the ST execute/block editing is far better, If you have alot of text in the old ST execute the editor window is very small and when online it's even worse. The new ST block seems a lot better Thanks!

Post by smartcoco on The text list provided outside the library is not available for visualization controls within the library. ^{CODESYS Forge talk (Post)}
I have a project called 'DemoProject' and a library called 'DemoLib'. Create a visual control named "DemoVisu" in the library, with a selection box of type "ComboBoxInteger" in the space. Now 'ComboBoxInteger' requires a 'Text list'. This "Text list" is provided when I call the "DemoVisu" control of the "DemoLib" library in "DemoProject". And this text list is in 'DemoProject'. I found that 'ComboBoxInteger' no longer works at this time. Other visual controls that use text lists also have this issue. I hope there is a good solution to this problem.

Post by benediktenger on Access project information of references library by script ^{CODESYS Forge talk (Post)}
Hi, I need to accesss to project information of a referenced library in the project. At least I need the "Released" flag from these information to check that no project gets shipped with unreleased libraries. Unfortunally, I do not get this information by script. I archieved to get the library reference object and the managed library object but both won't give me this flag but only basic information like company, name, version, etc. Here is my code: # get the library refernces proj = projects.primary objects = proj.get_children(recursive=True) for object in objects: if object.is_libman: for libref in iter(object): if libref.is_placeholder and isinstance(libref.effective_resolution,str): print(libref) print(libref.name) # get the managed libraries libs = librarymanager.get_all_libraries() for lib in libs: print(lib.displayname) print(lib.version) Does somebody know how do get these information?

Post by simotion on Pointer to Softmotion axis ^{CODESYS Forge talk (Post)}
In my projet I use Softmotion. There are several Softmotion axis (type SM_Drive_Virtual). In the Global Variable List I have an array of pointers to the adress of the Axis. Axis : ARRAY[1..iMaxCntAxes] OF POINTER TO AXIS_REF_SM3 := ADR(AX01_Axis), // [1 ADR(AX02_Axis), // [2] This works, but when compiling I get the message : . [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX01_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX02_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. Is there a way when initializing to force the hardware (softmotion axis) to first initialize and then the Global Variable List?

Post by pascaljt on Function block for Ethernet/IP ^{CODESYS Forge talk (Post)}
Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Ich versuche grade die Lizenz für den Revolution Pi zu aktivieren, das hat auch schon im Laufe eines Jahres 20 mal geklappt, jetzt bekomme ich grade nur die Fehlermeldungen zu sehen in den angehängten Screenshots. Die Aktivierung der OPC-Client Lizenz lief ohne Probleme geht nur um die aktivierung für die Codesys Control for Raspberry Pi MC SL. Ich habe sowohl die Webaktivierung versucht als auch in der Codesys IDE, im Lizenz Manager versucht die Lizenz zu aktivieren. Aktivierung mit Dongle kommt nicht infrage da die bei Endkunden eingebaut werden. Hatte jemand ähnliche Probleme, bzw. weiß jemand wie das zu beheben ist? MfG Jannis

Hallo, ich habe von Version 3.5.19.0 auf 3.5.19.40 hochgerüstet, jetzt bekomme ich bei allen FUNs die "to" im Namen haben einen Fehlermeldung. Oft in der OSCAT.LIB verwendet. Gleiche Meldung wenn ich einen FUN neu anlege. Sobald ich das to weglasse z.b. nur "t" ist der Fehler weg. Programm ist unverändert. Fehlermeldung: Typ.... wird nicht unterstützt. Hat jemand das gleiche Problem? Bzw. wo liegt das Problem? Bzw. nutzt jemand das SP4 und bei ihm kommt der Fehler nicht? Läuft bei mir auf Rasperry. Beispiel: DT_TO_SDT -> Fehlermeldung Typ DT_TO_SDT wird nicht unterstützt. DT_T_SDT -> Übersetzung Fehlerfrei

Hallo, ich habe https://store.codesys.com/de/codesys-in-building-automation-examples.html runtergeladen und mit dem Installer und Adminrechten installiert. Jedoch finde ich auf C: keine *.project* Dateien. Kann mir jemand erklären wie ich an die Examples dran komme? Auch von Wago habe ich Packages bekommen in denen Beispiele enthalten sind. Auch hier finde ich nix. (Googel habe ich gefragt. Aber mit den Stichworten kommen viele Treffer die alle nicht hilfreich waren.) In der Hilfe von Codesys habe ich natürlich auch gesucht, aber auch hier nichts erklärendes gefunden. Angeblich findet sich was in C:\Programme\CODESYS 3.5.19.40\CODESYS\Projects oder auch unter C:\Users\BENUZTERNAME\CODESYS Examples Aber wie geschrieben finde ich auf C:\ nix was ein Beispiel wäre. Wäre echt super wenn mir jemand einen Hinweis geben könnte. Danke im Vorraus, Martin

Hallo, mal wieder war der Fehler vor dem Computer, bzw. waren es die Programmierer. Die Dateien sind tatsächlich im Ordner C:\Users\BENUZTERNAME\CODESYS Examples Aber nicht in dem der vor dem Computer sitzt, sondern im Administrator-Verzeichnis. Eine mächtig dämliche Sache. Und das alles ohne Hinweise in irgendwelchen Anleitungen oder Meldungsfenster beim installieren. Bei meiner suche mit *.project habe ich natürlich keine Adminrechte, deswegen wurde mir nichts angezeigt. Danke an alle die meine Beiträge gelesen haben. Danke an alle die darüber nachgedacht haben :-) Vielleicht hilft mein Thread mal jemandem. Gruß Martin PS: Mache Firmen nennen die Beispieldateien nicht Examples sondern Samples.

Post by fabian on Sys Process Execute Command ^{CODESYS Forge talk (Post)}
Hello, I have a question: Once the command is being executed, is there a way to kill it again? As the called application is running in the background, the user can't close it but it shall be closed/terminated, commanded by codesys. I have tried with "SysProcessTerminate" but I guess this is not correct as the RTE crashes when this function is called. Starting the application: IF GVL.xStrtQR THEN GVL.xStrtQR := FALSE; SysProcess.SysProcessExecuteCommand2(pszCommand:=sCmd, pszStdOut:=stdout, udiStdOutLen:= SIZEOF(stdout),pResult := ADR(GVL.pResQRTsk)); END_IF Trying to stop it again: IF GVL.xTrmQR THEN GVL.xTrmQR := FALSE; pResTerm := SysProcess.SysProcessTerminate(hProcess:=SysProcess.SysProcessGetCurrentHandle(pResult:=ADR(GVL.pResQRTsk))); END_IF Codesyscontrol Win x64, 3.5.19.10. Many thanks for any advice pointing to the correct direction.. :-) Regards, Fabian

Post by felipemsgarcia on Edge Gateway online, but PLC is not online ^{CODESYS Forge talk (Post)}
Hello, Up until yesterday (2023/11/20) I was able to connect to the PLC remotely with no issues through Edge Gateway. However, today I can see the Edge Gateway online but I can find the PLC even if I do a network scan. Following the same path as janber0206 @ https://forge.codesys.com/forge/talk/automation_server/thread/e78b11d7e9/, I looked into certificates and found that one of the Trusted publisher certificates has expired earlier today (2023/11/21). Please see image. Questions are: Does it affect the connection to the PLC through Edge Gateway? How do I fix it? Thank you very much in advance!

Post by captaincookie on SP19 Runtime Zugriff auf lokales Dateisystem ^{CODESYS Forge talk (Post)}
Hallo, das konkrete Problem konnte ich seither leider nicht lösen, allerdings habe ich mit SP19 Patch 4 einen Workaround gefunden, der zumindest für meine Anwendung funktioniert: Zunächst besteht das Problem nicht für alle Funktionalitäten gleichermaßen. Die Anzeige einer .bmp oder .tiff-Datei im Visu-Elementtyp Bild beispielsweise funktioniert aus dem lokalen Dateisystem. Die Anzeige von .cnc-Dateien in einer Tabelle dagegen nicht. Allerdings funktioniert das wiederum, wenn der Dateipfad in den Ordner der PLC führt, genannt '_cnc'. In der PLC wird dieser Ordner über den Pfad _cnc/ erreicht. Auch lohnt es sich einen Blick in die PLC Config-Datei zu werfen und ggf. Anpassungen vorzunehmen. Einzelne Einträge definieren Zugriffsrechte und ähnliches. Die beschriebene Lösung ist nicht sonderlich schön und es erklärt das Problem nicht. Vielleicht kann das noch jemand anders beantworten.

seit SP19 nur noch im PLcLogic pfad. c:\ProgramData\CODESYS...usw datein schreiben lesen [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ PlaceholderFilePath.2=/media/usb, $USB$ PlaceholderFilePath.2.Volatile=1 Seit der Behebung kann der IEC-Code aus Security-Gründen nur noch auf das Arbeitsverzeichnis PLCLogic zugreifen. Sollte auf Dateien außerhalb dieses Pfades zugegriffen werden müssen, dann können diese per Platzhalter bekannt gemacht werden und sind dann zugreifbar. Darüber hinaus kann weiterhin ForceIecFilePath=0 gesetzt werden, um das bisherige Verhalten wiederherzustellen. Von letzterem raten wir aber dringend ab, da dann der IEC-Code wieder auf das gesamte Filesystem zugreifen kann. Daher sollte beides nur nach einer eingehenden Securitybewertung erfolgen.

Hello everyone, I want to establish communication between my Arduino and my Raspberry Pi via I²C, but I have no idea how to make it work. However, it should work because there are many examples available, although none of them were programmed using Codesys, but rather using Python. My Raspberry Pi will be the master and is supposed to exchange measurement data such as speed and battery capacity with the slave (Arduino). I would be very grateful if someone could help me with my problem. Here is another link that could be helpful. However, I can't find the mentioned libraries

Post by dkugler on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
I would figure out, how to create a simple html webpage with 2 frames. One frame with buttons to select the plc. A second frame with hyperlink to the webvisu of the plc ("XXX.XXX.XXX.XXX:8080/webvisu.htm"). Selecting other PLC Button has to change the hyperlink in 2. frame. Costs only some time to figure out :-) Or setup a raspberry Pi with small visualization. Set up a button for each plc and add one browser element. Each button writes the URL of the depending plc to the URL setting of the browserelement. Costs 55€ for runtime licence and a Raspberry Pi.

Post by niloufar on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Hi, Our program incorporates various function blocks and programs written in different languages such as St and SFC. They implement numerous actions and methods using different languages from their function blocks. My question is whether the execution order of function blocks is associated with the programming languages used. I understand that cycle time can be configured in the task configuration, but I'm curious if there is a specific sequence order of execution for function blocks written in different languages. For example, all function blocks in (ST) are executed first, followed by the execution of (SFC). Specifically, when the function is written in (ST) and the action is implemented in (SFC). I modified all function blocks in the main PLC program and configured a task configuration for the main program.

Post by manuknecht on Using SMC_MOVTYP.INITPOS without specifying the start position ^{CODESYS Forge talk (Post)}
I am using the object SMC_GEOINFO to generate a trajectory and move a system accordingly using the SMC_INTERPOLATOR function block similar to the sample project CNC10_DynamicPath.project. According to the documentation, the movement type INITPOS does not require a start position in the SMC_GEOINFO object, which is confirmed in the documentation of the SMC_GEOINFO object. When using the movement type INITPOS however, the motion will still start from the starting point defined in the SMC_GEOINFO object (0,0,0 if not specified otherwise). Does someone know how to resolve this or is there an example project that makes use of the INITPOS movement type without specifying the starting point? Thanks in advance!

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
I came up with an FBD that seems to be working, although it may not be a true Retriggerable Pulse timer. There may be some delay associated with the two MOVE functions and ADD function I incorporated. I'd be interested if anyone is able to come up with something cleaner. I am surprised that this is not a built-in function block of the CodeSYS library. This is a common feature of multi-function timer relays. I also attached a page from the cut sheet of a Schneider relay that shows 10 timing functions. Looks like the CodeSYS library has built-in function blocks for only 3 of the 10.

Eigentlich brauche ich nur sehr wenige Kommandos um unser Device zu konfigurieren. Das bedeutet setzen der MAC Adresse und einer Seriennummer. Das würden wir gern aus einem C# Programm herus machen. Nun sind wir auf der Suche nach einer Bibliothek o.ä. . Da man es ja auch aus Codesys heraus machen, dachte ich mir, gibt es eventuell eine DLL o.ä. die man dafür nutzen könnte. Wie gesagt wir wollen keine Realtime Abfragen der zyklischen Daten sondern lediglich Record read/write. Hat da jemand einen helfenden Hinweis ? Schon mal vielen Dank im Voraus
