Post by dom4u on Using PEAK CAN PCIe card (IPEH-004040) with Codesys Control RTE V3 ^{CODESYS Forge talk (Post)}
Some findings on this issue: PEAK CAN Driver is the same as in every PCI card from PEAK. I updated the inf file. Here are my steps: 1. Include right VendorID into the *.inf file 2. Disable Windows driver check (Disable WHQL check). This you need because 3S driver is not certified. You will find steps via google or ask chatgpt :) 3. Select: Select driver from a list and navigate to the folder. Say yes to install an uncertified driver. 4. Driver installed and device without errors I did the same with CAN Card from ESD, but here you dont need to include the vendor ID. In ANY CASE it was not successful. The RTIOwdmgeneric is not available in Codesys or anyhow accassable :( I wonder that it fails in two cases, two suppliers, two driver in the same way. How can RTIOwdmgeneric implemented into the project?

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
CoDeSys 3.5.19.7 Target Berghof MX6 In a simple SoftMotion programme with two stepperless modular axes from CMZ, one is simply controlled in speed, but a spot must perform a positioning. I use the function MC_SetPosition() both to reference the axis at power-up and also to correct the actual position to a fixed machine reference detected with proximity. The function has only one instance and I actually use a booelan variable to control the ‘Execute’ input. Well, I cannot correctly change the axis position on the fly if it is running at high speed. The servomotor works in a speed range between 0°/s and 720°/s, (gearbox output with a 1:6 ratio). As long as the servomotor is operating at speeds below about 400 °/s, the function is able to correct the position correctly even when forcing values far apart, but at high speeds, from 400 °/s upwards, the correction no longer takes place. For example, trying to correct the position of 280° into 300° with absolute mode, the axis that is moving at speed actually shifts the position by a few degrees, not the expected 20. I don't understand why with the servo drive running slowly the position shift occurs correctly, while increasing in speed it no longer works.

Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Here, it seems to me that we are getting completely off track with the observed problem. If questions clarifying the details of the installation are problematic, it's best to include those details in the original question then... I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. Testing the full program in emulation is entirely different from creating a simplified program to isolate the function causing problems in the real world. I would recommend trying it to isolate the issue. The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem A simple "yes" is the correct answer to my question here... Anyways, you seem to be a very knowledgeable expert, good luck on your problem!

Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

Post by imdatatas on Auto Declare window disappears by itself in the Ladder editor ^{CODESYS Forge talk (Post)}
Hello Everyone, The "Auto Declare" window disappears by itself in the Ladder editor. For example, a new function block is wanted to be added to the Ladder editor. (For example; MC_Jog block and instance name will be fbMcJog). To do this, "Empty box with EN/ENO" is added to the ladder line from the Toolbox on the right and when you type MC_Jog in the empty box and press enter, normally the "Auto Declare" window appears and you are expected to be asked to write the instance name here. However, this "Auto Declare" window closes itself immediately, it does not wait for the user to enter a value or close the window. I often encounter this situation in many IDE versions. Does this seem like a bug? If anyone has encountered a similar problem while creating a new program name, function or function block instance name regarding the "Auto Declare" window and knows a solution, I would be glad if you could share it. Best wishes Imdat

Post by egau on Enable and Disable Project IO programmatically ^{CODESYS Forge talk (Post)}
Hi @eschwellinger, I tried this with Modbus COM slaves. I was able to disable them (slave becomes greyed out in the device tree), but the DED.Reconfigure "eError" output shows "NOT_SUPPORTED". After this, when I tried to re-enable the slave, it did not work (device stayed greyed out in the device tree), and the DED.Reconfigure "eError" output also showed "NOT_SUPPORTED". Is there something to do about this, or the device just doesn't support reconfiguration? P.S: I tried this running locally on my computer (not in simulation mode). So of course I was not physically connected to the devices. I have two similar projects, but one of them doesn't have the Modbus_COM devices. I know I can "Exclude from build" the devices for that project, but I would really prefer not to do this if possible. I would prefer to dynamically toggle a configuration variable that would enable or disable the slaves.

Post by pistola on C0357: "GetNextClient" is obsolete, use VisuUtils instead ^{CODESYS Forge talk (Post)}
I'm having some troubles with this same issue and I'm wondering if someone can help me out. On a settings visual I allow the operator to enter some values however if they activate the page change button it will change the change with the Numpad dialog open. Since I'm using Visuelems.CURRENTVISU to change the pages I came across this code noted below for determining if the Numpad dialog was active. This code worked great however now in 3.5.19 it's now obsolete. I've tried following the directions in the attached program above however I can't see to get it to work in my program. Can anyone provide some help to determine if a dialog is open?

Post by nz-dave on MC_HOMING ^{CODESYS Forge talk (Post)}
Hi Just new to motion and i am building my own 3axis cnc cutter using servo drives. i have every thing working quite well apart from mc_home. when executed (r_trig) it stops immediately and i get fb_wasnt_called_during_motion. if i execute the mc_home fb with a toggle it just runs and runs for a while then errors out. what im unsure of is the way mc_home works. from what i understand it changes the drive mode to 6 (homing) and should then run of the drive homing settings. once origin sensor is made then homing would stop and mc_home.done is true. and the position on the fb is where i what the new home position (zero) to be? or do i feed mc_readposition to that input? so i would think its the settings in the drive that aren't quite right. but i believe they are all correct. has any one got any info to steer me in the right direction?

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 mondinmr on Unexpected behavior in cyclic encoder read method during INT overflow (wrap-around) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m investigating a potential issue with a cyclic method we use for reading incremental encoders in our libraries. I’ve come across two implementations that, at first glance, appear to perform the same operation: motionUnit.vlPositionActualValue is UINT due strange encoder type. Version A METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; rI: INT; delta: INT; END_VAR rI := TO_INT(motionUnit.vlPositionActualValue); delta := rI - actPosFieldOld; m_actPosRaw := m_actPosRaw + TO_LREAL(delta); actPosFieldOld := rI; IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Version B METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; END_VAR m_actPosRaw := m_actPosRaw + TO_LREAL(TO_INT(motionUnit.vlPositionActualValue) - actPosFieldOld); actPosFieldOld := TO_INT(motionUnit.vlPositionActualValue); IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Both use INT and the same delta logic, so they seem equivalent. However, when an overflow (wrap-around) occurs, version A continues correctly as expected, while version B unexpectedly resets to -32768 without a clear reason. Has anyone experienced similar behavior or can shed light on what might be happening here? It almost seems as if the cast to LREAL is being applied before the calculation — but that would be illogical and potentially very dangerous in many situations! 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 timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
We have been using the Codesys Control for Rasberry Pi for several years in many installations without any major issues. But during summer the problem mentioned above has blocked further deliveries. We have made some minor upgrades to the application but I do not really see why that should have any impact. HW is Raspberry Pi 4B, 2GB OS is Booworm Lite Codesys control is version 4.15 (have just installed a few systems lately with this version) The system boots OK but after exactly 30 seconds Codesys is shut down and becomes unreachable. We have tested several different combinations: Upgrade of the Codeys Control to 4.16 Loading different Codesys applications Changing to 4GB version of the Raspberry Pi One of the test applications together with the 4GB HW seems to be stable, but all other combinations fails. Any suggestion what we can do to resolve is appreciated - this is a real business blocker now. Rgds

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 beavel on Feature Request: Text List Formatting ^{CODESYS Forge talk (Post)}
Hi everyone, I'm working on a multilingual help system within a CODESYS visualization project and have run into a limitation with the current text list (.tlx) functionality. Right now, text list entries only support plain text, which makes it very difficult to format longer help texts in a readable way. For example, I’d like to: Use bold headers and larger font sizes for section titles Display variable names or keywords in italics Avoid having to split content into dozens of separate entries just to apply different styles This becomes especially unmanageable when supporting multiple languages — duplicating layout logic across languages is not scalable. Would it be possible to implement a Markdown text functionality for text list entries ? For example: #Header ##Sub-header 1.ordered 2.list 3.fun 4.times Alternatively, is there any existing workaround or planned feature that allows for styled text blocks without fragmenting the content? Thank you in advance and have a nice day :)

Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes...

On the Sysmac Studio end, I've made the variables and set them to network inputs/outputs, registered them in EIP settings, but when I try to set the target device (the Codesys project), I suspect I need to import an EDS file for the EIP mapping. Back in the Codesys project, I'm not sure how to: - Make an EDS file to share with Sysmac Studio - How to link the target device (Omron PLC) to the EIP fieldbus - How to map the inputs from the Omron PLC.

We have a setup of 10 Codesys controllers which features around 300.000 discoverable tags per controller. We are only interested in 10 percent of the tags to be communicated to the OPC-server, this is due to the fact the program consists of arrays of objects which on their part implements arrays of objects, simply reducing the number of discoverable tags is not an option The OPC-DA server loads all the discoverable tags, is it possible to: 1 let the OPC-DA server only load the tags that are requested by the SCADA/MES system. 2 let the OPC-DA server claim more memory. 3 run 2 OPC-DA servers in parallel?

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

Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

I have a project with a Festo CPX-E-CEC-C1-PN PLC (Run-time version 3.5.12.50) that I have been developing on just fine using Codesys V3.5 SP19 Patch 5 (64bit). I am at the stage where I wanted to use the Festo HMI screen, and have added a RemoteTargetVisu object to my application. After adding this object, I am no longer able to log in to the PLC as I get an Unresolved Reference warning for 'USERMGRUSERGETPROPERTY' towards the end of the download process. I was able to find this post (https://forge.codesys.com/forge/talk/Visualization/thread/fc686a6cb2/) where the two possible solutions are to "set the placeholder to emtpy" or update the runtime. Problem is, I don't know how to do either of these things, as I'm still very green in Codesys land. I'd be happy to update the Festo PLC runtime, as that seems like the better option, but have not had any luck in finding a tutorial for this online. If anyone could point me in the right direction I'd appreciate it.

Hi Duvan, You could make this in 1 single object (FB), Indeed don't use a function for this beacuse you need some memory to keep the old value. For i := 0 TO 200 BY 1 DO //Check if the value has been changed IF Old_Value[i] <> Value[i] THEN //Set the trigger to TRUE Trigger[i] := TRUE; Old_Value[i] := Value[i]; END_IF END_FOR If you define the Value array as an In_Out and the Trigger as an In_Out you arn't claiming any aditional memory to your system. You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR
