Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge talk (Post)}
I’m currently working on establishing a TLS connection with an MQTT broker using the MQTT Client SL package in CODESYS. While I’ve successfully established communication with the broker without TLS, I'm encountering issues when trying to enable TLS. In the 'MQTT Explorer' application, I can easily upload the server certificate (.crt), client certificate (.crt), and client key (.key). However, in CODESYS, I can’t find a way to upload my client key (.key file). Here's a summary of my current setup: Certificates: I have uploaded both the client and server certificates to the certificate store under the 'Trusted Certificates' folder in the security screen. TLS Context Initialization: Despite setting the _sCommonName as the name of my client certificate, a new self-signed certificate is created and placed within the device’s certificates. I then need to manually move this certificate to the trusted certificates folder. This results in three certificates in my trusted certs folder: client cert, server cert, and the newly created cert. _ciDefaultCertInfo : MQTT.NBS.CERT_INFO := (psInfo := ADR(_sCommonName), udiSize := TO_UDINT(LEN(_sCommonName))); // CN of the certificate (common name) _sCipherList : MQTT.NBS.CIPHER_LIST := STRUCT(psList := ADR('HIGH'), udiSize := 4); // Cipher string see https://www.openssl.org/docs/man1.1.1/man1/ciphers.html _tlsContext : MQTT.NBS.TLSContext := ( sUseCaseName := _sCommonName, // A certificate is stored in the certificate store with the use case name. You can choose any name. Here we use the common name. ePurpose := MQTT.NBS.PURPOSE.CLIENT_SIDE, // For client certificates set this to NBS.PURPOSE.CLIENT_SIDE sTLSVersion := '1.3', // The TLS version sCipherList := _sCipherList, // Set the cipher list sHostname := sHostname, // The hostname of the broker udiVerificationMode := 2, // 2 => Active Peer verification ciCertInfo := _ciDefaultCertInfo, // Set the cert info itfCertVerifer := 0); // 0 => No Verifier mqttClient : MQTT.MQTTClient := (xUseTLS:=TRUE, itfTLSContext := _tlsContext, itfAsyncProperty := _asyncProperty); Additional Details: In the client FB, I’ve set uiPort:= 8883, xUseTLS:= TRUE, and configured itfTLSContext as mentioned above. The certificates are encrypted with SHA256RSA. sHostname is the IP address of my broker. I’ve attached a copy of the client FB, which shows straight lines where variables are assigned and boxes where they are not. I am currently trying this on the only 2 compatible versions of COSDESYS with my controller (V3.5.15.20 and V3.5.18.40) My Question: How do I correctly set up this mTLS connection? What might I be missing? Any guidance or suggestions would be greatly appreciated, especially considering I’ve already successfully established a non-TLS connection with the same broker. Thank you in advance for your help!

Post by thommy54 on Lizenz wiederherstellen SP20 ^{CODESYS Forge talk (Post)}
Hallo Edwin, ich bräuchte mal eine schnelle Hilfe. ich testete einen zweiten Raspberry Pi 4 mit meinem Lizenzdongle eines laufenden Raspberry. Der 2. Raspberry ist als Redundanzlösung bei einem Crash gedacht. DIe Schwierigkeiten begannen, als ich mit dem Raspberry 4 V1.5 nicht mehr mit SP16 weiterarbeiten konnte. Ich updatede auf SP20.1. und die Schwerstarbeit begann. Das Image wurde rübergeschoben und alles auf dem zweiten Rechner soweit zum Laufen gebracht. Der Dongle wurde ebenfalls am 2. Rechner eingesteckt. Ob er überhaupt wirkte, kann ich nicht sagen, da für diesen Testfall Codesys so oft rauf und runter gefahren wurde, das die 2h-Grenze kaum erreicht wurde. Problem: Beim Zurückstecken des Dongles in den ursprücnglichen Rechner ist alles an Lizenzen weg. Der Lizenzmanager hat keinen Container mehr und der Befehl "lsusb" bringt nichts zurück. ich war der Meinung, das der Dongle genau für diesen Zweck gedacht war - die Lizenz von einem Rechner zum anderen mitzunehmen. Liege ich da falsch ? Wie komme ich nun wieder zu einem funktionfähigen Dongle ?? Weitere Versuche unternahm ich mit dem Wiederherstellen des Dongels. Dabei steckte ich ihn in meinen PC (Workstation) und siehe da, es werden noch 3 von ehemals (2020) 6 Lizenzzeilen angezeigt: (siehe Bild Problem_Lizenzen_Raspberry.jpg) Dann versuchte ich das Wiederherstellen über eine Lizenzaktualisierungsdatei vom Lizenzserver. Da kommt aber eine Datei mit anderem Dateityp (..WibuCmRaC) als im Lizenzmanager gesucht (WibuCmRaU). Die Datei ist dem Lizenzmanager auch nicht genehm (Bild Problem_Lizenzen_Raspberry_2.jpg). Nun steht Codesys auf besagtem Raspberry alle 2h still. Das soll die Lizenz doch verhindern. Angeblich soll seit SP13 auch kein eigenes Backup mehr nötig sein. Bis zum Erhalt des nicht brauchbaren Linzenzfiles hat da sja geklappt. Ich kann auch im Lizenzmanager keinen Punkt "Lizenz wiederherstellen" finden. Hat sich da mit SP20 etwas geändert? Wenn ich mir eine neue Lizenz hole - wie bringe ich sie auf den Dongle (der ja jetzt nicht "nagelneu" ist). Ich fürchte, das geht auch bloß schief. Im Voraus vielen Dank Thomas

Post by thn-power on Updating OPC UA Core Nodeset on PLS ^{CODESYS Forge talk (Post)}
Hi After much trail and error I think I found the root cause to my OPC UA problem. The problem is that I cannot manage to build and download a program with a a custom OPC UA Information model. We use a Weidmueller WL2000 PLS, but the problem also exsist on the Win V3 PLC. Our custom information model is based on the latest versions of the OPC UA Core Nodeset v 1.05.03 (2023-09-20) and UA/DI nodeset 1.04.0 (2022-11-03) Those nodesets are installed in the Codesys Information Model Repository (3.5.19.6) However, when trying to build I get the following error. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://bos.org/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/DI/ is required by http://bos.org/ with a minimal publication date from 03.11.2022 but the device has only a model from 09.03.2021 installed. Probably the information model from 09.03.2021 is missing in the information model repository. Build complete -- 2 errors, 1 warnings : No download possible I think the problem is that the UA Core nodeset is implemented in the PLC firmware (at least that in Siemens S7), and that only includes the "old" nodeset from 2021-09-21 etc. So the question is, how (or if?) can I transfer the new nodeset to the PLS? I have created separate Information models under Communication manager with the newer code nodesets (UA and DI). But it seems that the compiler does not recognize them being excising, neither in the Codesys IDE or on the PLC. Would have guessed that this is a common issue, sine many manufacturers use the latest versions of the OPC UA standard, and that it would be a solution to the problem.

Post by janderson on OPC UA Server limitations, large array crashes runtime ^{CODESYS Forge talk (Post)}
What are the limitations of the OPC UA Server? I am trying to get data off my PLC that is acquired at high rates (~50k samples/s) so I am storing them in arrays and trying to get the arrays off the PLC. When I attempt to read a ~200k element array through OPC UA the server and runtime crashes (requiring tools -> update linux arm64 -> start runtime). Is there a better way to get highspeed data off? The ACDatalog library seems a bit irritating to use so I would prefer to go through OPC UA.

Post by arnaud on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
Hi there! I'm using eCockpit WAGO software to develop HMI's for multiple projects. As I recently starting this, my knowledge on the software is somewhat limited (so maybe my question is a simple one). For most of my projects I can simulate the application and start it to test the code and HMI. However for two projects, I can initiate the "simulation activation" but I cannot start it. Nothing happens when I press start and the visualization shows "The online visualization is waiting for connection. please start the application". - I don't see any errors in the messages - Initially the project are made by a colleague, which moved on. I guess I'm forgetting something, like missing a setting. I appreciate any help I can get. If you need more information to help me out, let me know. Thanks!

Post by rossanoparis on How to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server ^{CODESYS Forge talk (Post)}
Hello at all I'd like to know how to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server. In the past, I tried to ask in "Forge" about this topic, but I could find neither help nor document informations about it. Reading the file "codesyscontrol.log" I see these logs OPC UA Server Started: Hostname: NTLRPICTRL01, Port: 4840 URL: opc.tcp://NTLRPICTRL01:4840 Loopbackadapter activated. **All available networkadapters are used.** Multithreading activated. 3 workers used. My controller, which is a Linux PC, has got two network cards eth0 and eth1 I whant to use the card with name "eth0" as a server for OPCUA and keep the "eth1" free for other stuffs. Is it possible ? Best regards Rossano

Post by tvm on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
ok, that's different than our issue then. We're using Schneider Electric M262 PLCs, and we've had it where certain web browsers cause the web server to only allow https connections, but it's not recoverable with a refresh. It usually requires a power cycle or even a full firmware flash. Your issue might have more to do with the timing. I don't know if it helps you, but we normally run our visu task at 200mS, with an update rate of 200mS. Seems to work. I went through this: https://faq.codesys.com/pages/viewpage.action?pageId=112525371 but it really seems like trial and error.

I have the directory right here: I need to correctly access the files in this folder through CODESYSControl.cfg. Here is my CODESYSControl.cfg where on the first lines there are a few lines: [SysFile] FilePath.1=/etc/, 3S.dat PlcLogicPrefix=1 That means that if I am going to use relative paths its going to go to from the PLCLogic directory right ?

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

Post by alimans on Hex string ^{CODESYS Forge talk (Post)}
Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

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 matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi, Is there a process to restore Persistence Manager files? I have backups of persistence variables used in a machine that is currently operating and tuned and all set points adjusted. There are about 500 persistence variables, they are building another identical machine. I would like to use Persistence Manager files from the first machine in the second also. I have tried copying the files and replacing them on the new RPI but then the Persistence Manager gets errors and then they are all reset to 0 etc I have tried adjusting the times to match. Instead of replacing whole file, I tried just changing the contents inside the file, but still does not work. I may be missing something here, but surely there must be a way to load a backup. Thanks!

Post by macros8 on Alarm Management - latched variable represented as Text list ^{CODESYS Forge talk (Post)}
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

Hi I am about to configure ALL GPIOs on a Raspberry Pi 3 model B V1.2. It seems that I have limited understanding of why not all the IO’s become available with the corresponding mapped IO’s – the 'dwInUse' contains mapping of the inputs from GPIO0 to GPIO27. But 'dwInputs' are only showing GPIO0 to GPIO8 and GPIO15 as available inputs. These mentioned inputs work fine You will be able to watch the limited mapped IO activity here: https://drive.google.com/file/d/1zz4PBNBfRZBF2YkiJ2VQxw6L9MBVji7R/view?usp=sharing Can you please bring your best idea on why GPIO09 to GPIO14 and GPIO16 to GPIO27 state are zero in the dwInputs register?

I'm getting closer to the error. The combination of STRUCT and ARRAY probably causes the strange behavior. As soon as the ARRAY is followed by a variable, the problem arises. Examples: X: ARRAY[1..2] OF INT; // okay Y: ARRAY[1..2] OF STRUCT; // problem Z: STRUCT; Z.ArrayOfInt[1]; // okay Z.ArrayOfStruct[1].Variable // problem // *update - array of array also causes the error A: ARRAY[1..2] OF ARRAY[1..4] OF BOOL; // problem I can't be the only one who has this problem. Or? Maybe there is a solution. Anyone? Or is it a bug after all?

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.

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.
