Post by struccc on Bibliothek: floatingpointutils ^{CODESYS Forge talk (Post)}
The issue s the byte order typically in this case. Can be especially problematic with floating point numbers - even more tricky if transferred with a word based protocol. It is a peasant way to try out the alternatives, dword order can be a-b-c-d, b-a-d-c, c-d-a-b, d-c-b-a where a is the most significant, d is the least significant byte. So all you need is to swap the bytes in your dword, until you get the expected result. If you don't want to mess writing code for this, I'd recommend CAA_Memory library for that: MEM.ReverseBYTEsInDWORD and MEM.ReverseWORDsInDWORD functions would definitively do the trick. Otherwise, can do like this: VAR dwIn : DWORD := 16#11223344; dwOut : DWORD; rOut : REAL; pIN : POINTER TO BYTE; pOUT : POINTER TO BYTE; END_VAR pIN := ADR(dwIn); //pOUt := ADR(dwOut); pOUt := ADR(rOut); pOut[0] := pIN[3]; pOut[1] := pIN[2]; pOut[2] := pIN[1]; pOut[3] := pIN[0]; Ugly, but does the job...

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne

Post by sean-barton on Ambiguous namespace in library dependencies ^{CODESYS Forge talk (Post)}
I am trying to install the MQTT Client SL in an existing project I have been working on for years. After adding the library to the project, and without adding any other code, upon building I get a C0180: Ambiguous namespace 'MBM' error between the memory block manager (MBM) in the NetBaseSrv dependency of the MQTT Client SL library and the memory block manager (MBM) in the CAA CanL2 dependency of the 3S CANopen stack library. I have tried: * setting "Only allow qualified access to all identifiers." in the properties for both the parent libraries. * deleting the 3S CANopen stack library. Upon (re)building the error simply points to another conflicting library - there are many. * deleting the Library Manager and rebuilding it. * adding the memory block manager library (used in the NetBaseSrv) manually and changing its namespace to MBM3S. None of the above allow me to access the MQTT library through its namespace (MQTT). Adding the memory block manager manually removes the C0180 error, but the MQTT library is not accessible - i.e. mqttClient : MQTT.MQTTClient; highlights the mqttClient as "Identifier 'MQTT.MQTTClient' not defined". Is there anything else I can try?

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Hello Everybody, I have created a project for an Eaton XC303 that sends lots of data to a router via UDP. It works fine. However, when there is more than one product connected to the router, then it is necessary to change the IP address of the Ethernet port 0, from e.g. 192.168.2.11 to 192.168.2.12 (second product). It is easily done via PLC Shell (setipaddr 0 192.168.2.12), but the people in production is struggling with the PLC Shell commands and I would like to create a Visualization page that will hide that. I used the instruction: eChangeIPResult:= SysSockSetIPAddress(strEthernetPort, strIPAddress); and it works, until the PLC resets. I already read some posts and it appears that I need to stop the Ethernet 0 port and Reconfigure it, but I am really struggling to find the right way to do it. Any help will be much appreciated.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have done the switch (linux mint, virtual windows through QEMU/KVM) now and is generally pleased. Have had problems in two areas initially. To bridge IP to the Virtual unit (solved), I overthought things initially. Solution. Configure manually a bridge in the mint-"network connections". Use that bridge in the Qemu settings as "Bridge device", "Device name": "name of the configured bridge" Figure out where to store the projects. I started out have the data in linux world (sort of) and linking it the windows with "virtio-fs". That had some serious impact though on git-handling. It seems that virtio-fs interpreted any file-path as lowercase only even if there were uppercase, resulting in git not able to sync files between its repository and the source code (it created a new file-path for me with only lowercase). Then I switch to samba-share instead and this works much better, though (git-actions) is a part that still has low performance with lots of waiting for file-actions. What should be the best way of handling the source/git? Edit to answer myself: Save the project "locally" in windows, then a lot of slow performance is avoided. Then a git-remote sync for backup.

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
Thank you for your input! What I'm ultimately trying to achieve is automated test execution as part of a CI/CD pipeline (e.g. in GitLab or Azure DevOps). For this, I need to: Open a CODESYS project via script Build the project Run the Test Manager tests from a .TestRepository.xml Collect test results (e.g., pass/fail + a report) Exit with a proper return code (for pipeline success/failure) To integrate this into automation, I’m using the CODESYS scripting engine via Python (headless), but the issue is that the get_testmanager() function isn't available on the project object — even though Test Manager is installed, licensed, and works interactively in the IDE. Are you suggesting that I should: Use the Test Manager GUI to script the logic with its internal scripting language? Or is there a way to launch the Test Manager in headless/scripted mode, while still being able to control things via Python? If there's a supported way to automate tests with the Test Manager using scripting, especially from pipelines or headless environments, I’d really appreciate any pointers or example workflows. Thanks again!

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Looking for thoughts on creating libraries that can be used on both 32-bit and 64-bit controllers. We are currently writing software in CoDeSys for both target types and will continu to do so for the near future. Projects are always unique, no straight forward copy/paste, yet there is enough similarity between them to use libraries for recurring logic. I do not want to create and maintain twice for both platforms if this is not absolutely necessary. I am aware of useful datatypes like __XWORD, __XINT, __UXINT. Still looking for more information and/or sample code for portable pointer arithmetic. In addition to that: how should one go about when creating and working with compiled libraries? Would I need to compile the same lib twice, once for 32-bit targets once for 64-bit targets? I would end up with two different libs with the same namespace, which does not sound elegant to me. Note: I did not intentionally make the previous paragraph bold. The forge forum software seems to do this automatically upon insertion of a word which starts with two underscores, e.g. __XWORD (yeah, here we go again :) )

Post by leandroct on Creating Boot Application not working ^{CODESYS Forge talk (Post)}
I have a Control Win V3.5 SP20 (64-bit) application, and until now, I open the program (with a password) and download it. However, I need to give the client the option to install the program on the Controller, without them having to open it and access the code. So, I followed these steps: 1 – In the Online => Create Boot Application menu, I saved the generated files in a directory: Application.app Application.crc PlcLogic\visu\ directory with several files 2 – In the SysTray, I ran the PLC, and it created a directory. In the root of this directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E84889DB), I pasted Application.app and Application.crc. Since it created a \visu directory, I pasted the PlcLogic\visu\ files generated in Create Boot Application into it. 3 - In the general Codesys directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64), I edited CodesysControl.cfg, adding: [CmpLog] Application.1=Application 4 - When running the PLC, nothing happens and the TargetVisu screen does not open. What I'm doing wrong?

Post by vahasa on CAN TPDO / RPDO ^{CODESYS Forge talk (Post)}
Hi I'm automation engineering student and I'm not yet quite familiar with CAN-bus. What I am trying to achieve, to send two byte message via CAN from Epec display to Scott Drive inverter. I'm using code template made with Epec Multitool in Codesys 3.5 Problem i'm facing is that drive responds with same COB-ID. In multitool, you can create TPDO/RPDO. And depending on that, display either sends or only receives. This is problem, because for parameter polling from drive, you need to send two byte request to 0x399 and drive responds with eight bytes. If request is longer, drive don't respond. 0x399 is currently setted as RPDO, so display doesn't send anything on startup and I made program that sends messages to 0x399 bytes 0 and 1 and bytes 3-7 are shown in display. If setted as TPDO, display send all eight bytes and therefor drive cannot respond. But, I think because they are defined as RPDO, display won't send message, although monitoring with Codesys, values are changed. Question is, how should COB-ID be configured in Codesys, so it wouldn't automatically start to send message but would send when needed?

Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4.

Post by axilleas on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
dear all I am working on a very generic gantry system (virtual drives + win v3 control) reading gcode from external file. In order to stop the interpolator function from running when gaps are detected, SMC_controlAxisByPos FB has the bStopIpo output which according to the manual is connected to the Interpolator's bEmergencyStop. Lets assume that the axis are parked in position X1000 Y1000 and the initial G code movement is G00 X500 Y500. The normal behavior is to travel from the actual x1000 y1000 to G00 X500 Y500. The SMC_Interpolator always gets the X0 Y0 as the initial position, meaning that the bStopIpo is active until the axis are in X0 Y0 and the release the interpolator to set the new positions to X500 Y500. Is there a suggested method to solve this behavior? bonus question: I get a lot of bStopIpo during standard interpolation movements (not gaps). While working with virtual axis this is not a problem but when real axis are installed this will be an issue. What exactly triggers the bStopIpo output? Slow axis accelerations compare to Gcode defaults? Kind Regards

Hey there, I am currently trying to find a good solution for the communication between CODESYS Control on Raspberry Pi and "the rest of the world", i. e. the things apart from CODESYS on my linux. My first approach was to use the c-integration. So I created a lib, defined extern fbs, compiled the code on my Pi using the SDK and put the .so into my lib project. When I try to log into the Pi and load the program, I get the error message which you can see in the attached picture. "Die dynamischen Module der C-Integration konnten nicht auf das Laufzeitsystem geladen werden" is german and means roughly "the modules from the c-integration could not be loaded onto the runtime system." Is this normal? Am I doing something wrong? I will have a look at the unix domain socket thing next, as I am still in the process of finding the best solution for the communication.

Post by alex00 on DCS / Central Engineering with Codesys support ^{CODESYS Forge talk (Post)}
Hello together I'm currently investing in possibilities to have a central engineering software / system for Codesys based controllers. Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Post by francescoc on Custom log CmpLog ^{CODESYS Forge talk (Post)}
Hi, I am trying to create a log in my application. Since I cannot find any documentation regarding modifying the codesys configuration file to be able to log in ms, i tried to create a new log via CmpLog.LogCreate. Below is the part of the code where I create the logger and write a test string. In the log tab of codesys I actually see the new log that was created, but it is empty, and in the folder I cannot find any files. I can't find any detailed documentation. Can you guys give me support? Are there any examples? Thank you IF NOT FirstCycle THEN LogName:= 'LOGS/TestLog'; LogOptions.bEnable:= 1; LogOptions.iMaxEntries:= 5000; LogOptions.iMaxFiles:= 100; LogOptions.iMaxFileSize:= 5000; LogOptions.szName:= LogName; LogOptions.uiType:= CmpLog.LogTypes.LT_TIMESTAMP_RTC_HIGHRES; LogOptions.uiFilter:= CmpLog.LogClass.LOG_ALL; LogHandle:= CmpLog.LogCreate(pOptions := ADR(LogOptions), pResult:= ADR(Result)); LogHandle:= CmpLog.LogOpen(pszName:= LogName, pResult:= Result); Component_Manager.CMAddComponent2('TestLogNEW', 16#00000001, ADR(udiCmpIdNEW), 0); CmpLog.LogAdd2(LogHandle, udiCmpIdNEW, CmpLog.LogClass.LOG_INFO, 1, 1, 'Logger started...'); END_IF IF TestWrite THEN TestWrite:= FALSE; CmpLog.LogAdd2(LogHandle, udiCmpIdNEW, CmpLog.LogClass.LOG_INFO, 1, 1, 'Write test'); END_IF
