Post by timvh on Converting each character to a string into ASCII ^{CODESYS Forge talk (Post)}
A standard string is actually a list of bytes that represent the ASCII code for each character. The following part of code will give you the ASCII code of one of the characters in the string: byChar := sInput[i];

I also installed your codesys version with the codesys for raspberry pi package version 4.7.0. but with no succes, only the TCA multiplexer has a constant green turning circle, the ADS1115 still changing from running to not running.

maybe the compiler of the IDE can only use this color and other colors have to be licensed? But seriously, I agree with the request.

Post by rkohser on Scripted Git clone / checkout being blocked by "Project Environment" popup ^{CODESYS Forge talk (Post)}
Hi, I am trying to build a CI/CD pipeline around our codesys projects. The only entry point if the git url and branch, as we do not put our project file under source control, so we needed to find a way to git clone from the python scripting engine. This is currently how we do this : system.commands["Git", "Clone"].execute( "ProjectLocation=" + project_dir, "ProjectName=" + project_file_name, "RemoteUrl=" + project_git_remote_url, "GitProjectStoragePath=" + project_git_local_dir, ) system.commands["Git", "Checkout", "Branch"].execute( "PrimaryProjectHandle=0", "BranchName=origin/" + project_git_branch ) This works fine, except that, depending on the environment and the project, the "Project Environment" popup gets displayed to suggest for some updates, and waits for a user interaction, even with the "--noUI" flag injected as parameter. I investigated the VersionUpdateFlags, but the problem is that the git clone is an atomic operation that clones and directly opens the generated project without the possibility to inject any updateFlags argument (only used in the ScripProjects.open() function. I also tried to simulate some keyboard events acknowledge the window from script but I did not find the right location for the SendKeys statement, I think before the git clone call is too early and after is too late. So I am wondering if there would be some other way to do that. Is there some more proper scripting api for the git add on ? Is there a global configuration of the VersionUpdateFlags that would allow the popup to be disabled outside from any project context ? Is there some way to automatically acknowledge this kind of messages in a "--noUI" mode ? What do you suggest ? Thanks for your help, Roland Edit : I managed to solve my problem by following these steps in my pipeline : - create a template of a project and opt file preconfigured not to open the popup - open this project - initialize an empty git repo - add the remote, fetch and checkout the needed branch -> no popup is displayed, hourra Edit2 : The initial question was raised on a CODESYS V3.5 SP18 Patch 2 profile. Since CODESYS 3.5.19.30 a scripting API is available for Codesys Git that allows cloning a project with the support of VersionUpdateFlags https://content.helpme-codesys.com/en/CODESYS%20Git/_git_using_scripting.html

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 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 jari-koivuluoma on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge talk (Post)}
I have a need to send messages between 2 PLCs and I cant use network variables (because of size limit) so I tried writing this simple test program. This seems to work fine. I can send messages back and forth when a first "Start server" and then "Connect client". See the attached image. However, if I disconnect the client by setting ClientConnect to false and try to re-connect then the TCP_Client just gives me TIMEOUT error. When I stop and start the server again, then Im able to reconnect. How is this supposed to work? Why reconnecting wont work. There is not other way of disconnecting the client than setting xEnable of the TCP_Client to false. This is just a testing program and I will try it on 2 seperate devices once this works.

Post by hwillems on Ranges, Lambdas, on Fixed arrays of structs ^{CODESYS Forge talk (Post)}
I do datastructures and algorithms in Codesys. For example a Struct of Person with thing's like IdNumber, Name, Age etc. as example. Now i do all kind of calculations, filters. So i have this pretty big Fixed Array with Structs. On this struct i want to do simple stuff you can do easily in C++/Python/Rust etc. For example i want to do this: AvererageAge := Average(Peoples.Age); Then it will return the average of all members ages. Or Sort struct on age etc. Or sort on alphabetical Name. Or use Lambda functions to filter/mutate out things like, filter out everybody above 18 years old. Or remove people who it's name start with "A". Currently i have to write my own custom function for example sorting on Age. And make a super specific function based on that particulare datastructure. Here an Example: (*Before calling this FIlter method, set the mNodeFilterSwitch to the desired filter.*) CASE mNodeFilterSelect OF (********************************[ Status Filters ]***********************************) NodeID: FOR x := ACS_OUT_BEGIN TO ACS_OUT_END BY 1 DO FOR y := ACS_IN_BEGIN TO ACS_IN_END BY 1 DO IF marrNode[y].Status.oiNodeID > marrNode[y + 1].Status.oiNodeID THEN mNodeTemp := marrNode[y + 1]; marrNode[y + 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; Started: FOR x := DES_OUT_BEGIN TO DES_OUT_END BY -1 DO FOR y := DES_IN_BEGIN TO DES_IN_END BY -1 DO IF marrNode[y].Status.oxStarted > marrNode[y - 1].Status.oxStarted THEN mNodeTemp := marrNode[y - 1]; marrNode[y - 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; Starting: FOR x := DES_OUT_BEGIN TO DES_OUT_END BY -1 DO FOR y := DES_IN_BEGIN TO DES_IN_END BY -1 DO IF marrNode[y].Status.oxStarting > marrNode[y - 1].Status.oxStarting THEN mNodeTemp := marrNode[y - 1]; marrNode[y - 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; END_CASE; I have like 30+ of these in the enum. Not really DRY code right? These are custom made bubble sort filters in a function. You pass in the Datastructure, and say what function you want. (This is an enum collection of sorting functions) And then the Array with Nodes of Structs gets ordered. Why can't we have Iterators and Lambda's and build in standard functions like regular languages? Also i use bubble sort because it's the easiest to implement because i can't get this to code DRY. Problem with ST (Even the new one with classes) that it's very limited for programming datastructures and algorithms. Yes you still not want dynamic memory and you need to choose the correct algorithm so you know the most extreme edge cases regarding the time it takes to execute the algorithms.(Real-time execution) How are other people dealing with this? Here for example saw some software using an adjusted ST language and having FOR EACH possibility: https://www.fernhillsoftware.com/help/iec-61131/structured-text/st-for-each.html You can then build your own custom Iterator functions. I wish the IEC 61131-3 standard would be more expressive and having more standard modern features, but still keep close to the fact of no dynamics memory and real-time systems.

Post by scoob on ModbusFB - Slow Response Time ^{CODESYS Forge talk (Post)}
Hello, I have been trying to use the ModbusFB functions so I can put some code into libraries, but it seems to be very slow for me. I have a Modbus device with 100ms registers. I previously setup 10 channels in the 'traditional' Modbus Slave with channels and mappings - and set a cyclic trigger at 100ms - this worked fine. I then tried the ModbusFB example, and setup reading the same 10 blocks of modbus addresses, copying the example and putting all of the requests into an array and triggering the requests sequentially. I timed how long the requests are taking to get round to each one, and it is around 1s 450ms. How do I speed this up to match the cyclic time? IF NOT(init) THEN init := TRUE; // Set the required IP address: ipAddress[0] := 192; ipAddress[1] := 168; ipAddress[2] := 1; ipAddress[3] := 10; // Pass the required IP address to the clinet FB: client_NetworkSwitch.aIPaddr := ipAddress; client_NetworkSwitch.udiLogOptions := (ModbusFB.LoggingOptions.ClientConnectDisconnect OR ModbusFB.LoggingOptions.ClientReceivedValidReplies); // Try to connect the client client_NetworkSwitch(xConnect:=TRUE); // Configure all the channels to read connecting them to the client: portStatus_Request(rClient := client_NetworkSwitch, uiStartItem := 4096, uiQuantity := 32, pData := ADR(portStatus), udiReplyTimeout := udiReplyTimeout); portSpeed_Request(rClient := client_NetworkSwitch, uiStartItem := 4352, uiQuantity := 32, pData := ADR(portSpeed)); flowControl_Request(rClient := client_NetworkSwitch, uiStartItem := 4608, uiQuantity := 32, pData := ADR(flowControl)); linkUpCounter_Request(rClient := client_NetworkSwitch, uiStartItem := 5888, uiQuantity := 32, pData := ADR(linkUpCounter)); txPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8192, uiQuantity := 100, pData := ADR(txPacketCounter1)); txPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8292, uiQuantity := 28, pData := ADR(txPacketCounter2)); rxPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8448, uiQuantity := 100, pData := ADR(rxPacketCounter1)); rxPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8548, uiQuantity := 28, pData := ADR(rxPacketCounter2)); txErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8704, uiQuantity := 64, pData := ADR(txErrors)); rxErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8960, uiQuantity := 64, pData := ADR(rxErrors)); // Trigger all client requests initially FOR clientRequestsCnt := 0 TO (SIZEOF(clientRequests)/SIZEOF(clientRequests[0]))-1 DO pClientRequest := clientRequests[clientRequestsCnt]; pClientRequest^.xExecute := TRUE; END_FOR // Prepare sequential trigger / control of client requests. clientRequestsCnt := 0; pClientRequest := clientRequests[clientRequestsCnt]; END_IF // Call the client to do request processing: client_NetworkSwitch(); // Now we trigger client request sequentially ... IF NOT pClientRequest^.xExecute AND NOT pClientRequest^.xDone AND run AND client_NetworkSwitch.xConnected THEN pClientRequest^.xExecute := TRUE; END_IF // .. and check result/error IF pClientRequest^.xExecute AND run AND client_NetworkSwitch.xConnected THEN IF pClientRequest^.xDone THEN // Prepare next trigger of client request (a rising edge of xExecute) pClientRequest^.xExecute := FALSE; IF clientRequestsCnt < SIZEOF(clientRequests)/SIZEOF(clientRequests[0])-1 THEN // next client request clientRequestsCnt := clientRequestsCnt + 1; ELSE clientRequestsIterationCounter := clientRequestsIterationCounter + 1; clientRequestsCnt := 0; END_IF pClientRequest := clientRequests[clientRequestsCnt]; END_IF END_IF I did try a semi-coded way using the IoDrvModbusTCP library, and setting the slave com settings, then 10 commands and 10 requests, then using a TP on xDone as a pause, before triggering another request - this is time the delay is around 120ms - so the device is fine with the speed, just something I am doing wrong in the ModbusFB method I am sure.

Post by mondinmr on Why SysPipeWindows is not implemented in RTE? ^{CODESYS Forge talk (Post)}
This library would be very useful for IPC communications. Using a UDP socket on localhost is unpredictable, as with slightly loaded machines it does not even guarantee packet delivery locally. Using TCP creates a lot of overhead. Message named pipes would be an excellent solution for Windows RTE. On Linux, since the release of the extension package, there is no issue, as it is sufficient to develop a component. However, although now 90% of our clients understand that Linux runtimes are better in every way compared to Windows RTE, especially from the security aspect (Not in kernel space) and the issues with Windows updates, 10% stubbornly insist (sometimes for trivial commercial reasons) on using Windows. Managing IPC with circular buffers in shared memory is quite ugly, or rather really ugly and unaesthetic. In the manuals, I saw the SysPipeWindows libraries, so I decided to test them, but unfortunately, I noticed that they are not implemented for RTE devices. Technically, I could try to open them as regular files, but SysFileOpen returns 16#27 or 16#39 depending on how I set the name (direction of the slashes). Here is the code to create shared memory and named pipes. Shared memory work great, named pipes no! #ifdef Q_OS_WIN32 SECURITY_ATTRIBUTES sa; SECURITY_DESCRIPTOR sd; InitializeSecurityDescriptor(&sd, SECURITY_DESCRIPTOR_REVISION); SetSecurityDescriptorDacl(&sd, TRUE, NULL, FALSE); sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.lpSecurityDescriptor = &sd; sa.bInheritHandle = FALSE; const wchar_t* name = L"Global\\ShmTest"; HANDLE hMapFile = CreateFileMapping( INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, 0, sizeof(SharedData), name); if (hMapFile == NULL) { qCritical("Error creating shared memory"); return 1; } data = static_cast<SharedData*>(MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, sizeof(SharedData))); if (data == NULL) { qCritical("Error mapping shared memory"); return 1; } HANDLE hPipe = CreateNamedPipe( TEXT("\\\\.\\pipe\\MyPipe"), PIPE_ACCESS_DUPLEX, PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, 1024 * 1024, 1024 * 1024, NMPWAIT_USE_DEFAULT_WAIT, &sa); if (hPipe == INVALID_HANDLE_VALUE) { qCritical("Error creating named pipe"); return -1; } if (!ConnectNamedPipe(hPipe, NULL)) { qCritical("Error connecting to named pipe"); return -1; } checkPipe(hPipe); #endif

But still CODESYS development system reports that it needs a dongle and when I click install that "value cannot be null. Parameter name: containerToLicenses" It seems that Codemeter is forced to look for a dongle instead of a CMsoftcontainer. Can you confirm that CODESYS licensing works also when CODESYS is installed in a Docker container?

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

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.

Post by andrej on Threads and TID created by CODESYSControl Win V3 ^{CODESYS Forge talk (Post)}
Hi all, for a deeper understanding of the Codesys RTE - I created a simple application with 3 IEC tasks (Ta,Tb,Tc) each with different priorities, and different cycle times. The application runs on Windows 10 in the Soft PLC CODESYS Control Win V3. If my understanding is correct, the RTE i.e. the Process CodesysControlService should spawn 3 threads (Th_a,Th_b,Th_c) which are executed with the defined cycle times, the priority of the threads should reflect the priority of the task set in the Codesys IDE. Does somebody have an idea, how I could identify the respective threads in Windows? Kind regards Andrej

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Post by bahrt on Mapping GPIO and adding GPIO configurations ^{CODESYS Forge talk (Post)}
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? Thanks in advance. Best regards Andreas Bahrt
