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 andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?

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 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? FUNCTION Check_Dialog_Open : Bool VAR_INPUT sDialogName : STRING; // Input variable for the name of the dialog END_VAR VAR pstClientData : POINTER TO VisuElems.VisuStructClientData; // Pointer to the client data structure itfDialogManager : VisuElems.IDialogManager; // Interface for the dialog manager itfMyDialog : VisuElems.IVisualisationDialog; // Interface for the specific visualisation dialog END_VAR // Begin the iteration over the client manager VisuElems.g_ClientManager.BeginIteration(); // Loop through each client until no more clients are found WHILE (pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO // Get the dialog manager interface itfDialogManager := VisuElems.g_VisuManager.GetDialogManager(); // Get the specific dialog interface using the dialog name itfMyDialog := itfDialogManager.GetDialog(sDialogName); // Check if the dialog is open for the current client Check_Dialog_Open := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog, pstClientData, itfDialogManager); // If the dialog is open, exit the loop IF Check_Dialog_Open THEN EXIT; END_IF END_WHILE

Post by shaunvdm on Canbus Slave SDO Read from Object ^{CODESYS Forge talk (Post)}
Busy testing a solution to use Canbus Slave to replace a physical device and convert to Ethercat device but keep the Canbus Master in place. Master needs to Read SDO object 5FA2. In the Master PLC if i send the SDO with 8 bytes in message IE: 60B 40 A2 5F 00 00 00 00 00 i get my expected 58B 43 A2 5F 00 00 68 36 02 containing data back. Problem is if we issue a 4 byte command can send 60B 40 A2 5F. Surely the canbus slave should respond with a 58B 43 A2 5F 00 00 68 36 02 but it comes back as 80 A2 5F 00 00 00 00 08 - meaning this OBJECT does not exist. Is there a setting in the canbus slave driver for Canbus to allow the 4 byte command to read the SDO OBJECTS ?

Post by darko7417 on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
I run CODESYS runtime as a service and use CmpLog (the LogAdd2 function) to log different events to a file. I have done this many times before on various projects and hardware, and it works fine. On this particular system, I have CODESYS 3.5.20.40 running on a Windows 11 PC. The CODESYSControlService autostarts (with Local System credentials, the default), and the application runs fine. However, the configuration file is not read (or at least not the one that should be, or not the CmpLog section), and log files are not written to the disk. I would be thankful if anyone knew why this is happening and how to fix it. A note to CODESYS people: you must provide more information on the codesys configuration file, CODESYSControlService.exe and other major components and system behaviour. You created the service and various features (i.e. logging), but haven't explained how they work, which, in my opinion, is below standard for industrial automation software. These are my observations: - When running as a service, the config file is not read (none of them), or at least the CmpLog section is not read. I checked the log using Codesys IDE, and the CmpLog parameters are not the ones I have set in any of the config files. Which CmpLog config values does the service use, and where does it read them from? I have no idea, but it's not the config files. Here are the codesys config files I located on the PC's disk: o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControl.cfg (only 2 lines in this config) o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\AppDataFiles\CODESYSControlWinV3\CODESYSControl.cfg o C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\tempCFG\CODESYSControl.cfg - When I run codesys as an app (e.g. by clicking the icon), this config file is read C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg and log files are written ok. The icon target is "C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControlService.exe" -d o the -d option, I think, starts a cmd-like window showing service debug output (the output shown in log in the IDE) o the -i option, again I think, means install the service - I tried adding -d to service start parameters in the registry, but it started only once and after that it refused to start. Knowing what -d does and which other options are available would be great (e.g. can I make the service read a different config file). - Syslog UDP logging works fine in any case. - These are my CmpLog parameters ~~~ [CmpLog] Logger.0.Name=PlcLog3 Logger.0.Filter=0xFFFFFFFF Logger.0.Enable=1 Logger.0.MaxEntries=10003 Logger.0.MaxFileSize=50003 Logger.0.MaxFiles=33 Logger.0.Backend.0.ClassId=0x0000010B ;sends logger messages to SysOut Logger.0.Backend.1.ClassId=0x00000104 ;writes logger messages in a file Logger.0.Backend.2.ClassId=0x00000135 ;sends logger messages as UDP syslog Logger.0.Type=0x314 ;Set the timestamp to RTC ~~~

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. PROGRAM PLC_PRG VAR CONSTANT mySize : UDINT := 255; END_VAR VAR Server: NBS.TCP_Server; ServerIpStr: STRING := '127.0.0.1'; ServerIP: NBS.IP_ADDR; ServerPort: UINT := 50000; ServerConnection: NBS.TCP_Connection; Client: NBS.TCP_Client; ServerRead: NBS.TCP_Read; ServerWrite: NBS.TCP_Write; ServerSend: STRING(mySize); ServerReceive: STRING(mySize); ServerConnect: BOOL; bServerSend: BOOL; IP: NBS.INADDR; ConnectedClientIP: STRING; ClientPort: UINT := 50000; ClientIpStr: STRING := '192.168.1.49'; ClientIP: NBS.IP_ADDR; ClientRead: NBS.TCP_Read; ClientWrite: NBS.TCP_Write; ClientSend: STRING(mySize); ClientReceive: STRING(mySize); ClientConnect: BOOL; bClientSend: BOOL; Error: BOOL; Message: BOOL; END_VAR // Server ServerIP.sAddr := ServerIpStr; Server( ipAddr := ServerIP, uiPort := ServerPort ); ServerConnection( xEnable := Server.xEnable, hServer := Server.hServer, ); IP := ServerConnection.IPAddress; ConnectedClientIP := F_Concat7( BYTE_TO_STRING(IP.S_un_b.s_b1),'.', BYTE_TO_STRING(IP.S_un_b.s_b2),'.', BYTE_TO_STRING(IP.S_un_b.s_b3),'.', BYTE_TO_STRING(IP.S_un_b.s_b4)); ServerRead( xEnable := ServerConnection.xActive, hConnection := ServerConnection.hConnection, szSize := SIZEOF(ServerReceive), pData := ADR(ServerReceive) ); IF ServerRead.xReady AND ServerRead.szCount > 0 THEN Message := TRUE; END_IF IF ServerRead.eError > 0 THEN Error := TRUE; END_IF ServerWrite( xExecute := ServerConnection.xActive AND bServerSend, hConnection := ServerConnection.hConnection, szSize := LEN(ServerSend)+1, pData := ADR(ServerSend) ); IF ServerWrite.xDone THEN bServerSend := FALSE; END_IF IF ServerWrite.eError > 0 THEN Error := TRUE; END_IF // Client ClientIP.sAddr := ClientIpStr; Client( xEnable := ClientConnect, ipAddr := ClientIP, uiPort := ServerPort, udiTimeOut := 10000000 ); ClientRead( xEnable := Client.xActive, hConnection := Client.hConnection, szSize := SIZEOF(ClientReceive), pData := ADR(ClientReceive) ); IF ClientRead.xReady AND ClientRead.szCount > 0 THEN Message := TRUE; END_IF IF ClientRead.eError > 0 THEN Error := TRUE; END_IF ClientWrite( xExecute := Client.xActive AND bClientSend, hConnection := Client.hConnection, szSize := LEN(ClientSend)+1, pData := ADR(ClientSend) ); IF ClientWrite.xDone THEN bClientSend := FALSE; END_IF IF ClientWrite.eError > 0 THEN Error := TRUE; END_IF

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 cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

Post by psychoengineer on Cannot Save CSV File on Windows Computer Using CODESYS and Control Win ^{CODESYS Forge talk (Post)}
I am currently working on a project using CODESYS and Control Win on a Windows computer. I've encountered an issue where I am unable to save a CSV file. I have followed the standard procedures and used the appropriate file handling functions, but the file is not being created or saved as expected. IF xStartTest THEN sFileName := '\logs.txt'; sFileName := CONCAT(gvl.g_sMainDirectory, sFileName); sFileNameCopy := '\CAAFileCopy.txt'; sFileNameCopy := CONCAT(gvl.g_sMainDirectory, sFileNameCopy); //eWriteState := FILE_OPEN_TRIGGER; xTestDone := FALSE; xError := FALSE; xStartTest := FALSE; END_IF VAR_GLOBAL g_sMainDirectory : STRING := 'C:\LogFiles'; // file path for CSV file END_VAR Despite this, the file does not appear in the specified directory, and no error messages are being generated. I've checked the directory permissions and ensured that the path is correct. Has anyone else experienced a similar issue or have any suggestions on how to resolve this? Any help would be greatly appreciated. Thank you!

Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
The probelm arises for the B&R T30 panel after updating Codesys from 3.5.17 to 3.5.19 patch 5. We have to use 3.5.19 for other reasons so we cannot downgrade the version. The scaling problem only exists for the B&R 6PPT30.0702.20F025 panel, the B&R T50 panel and a esa lumia panel work. When we choose a fixed resolution it looks also good, however we also want to support the esa lumia panel with a different resolution. The images show the anisotropic and isotropic option. In the anisotropic option it scales the hight correctly but not the width and in the isotropic option is scales both hight and width false, it also does not start in the top left corner. Does someone have any suggestion why it does not work anymore with the new codesys version and are there workarounds? I added all versions with visualization packages as an image, visuElems is 4.4.0.0.

Post by abauza on Image Pool using in other libraries ^{CODESYS Forge talk (Post)}
Hi im Albert, im developing libraries for my PLCs and i have some issues on visualization part. First of all I have done a library that have a image pool with a list of 4 gifs "ImagePoolErrors" (i've tested in other projects and it works) but the problem comes when i create another library that in the visualization part contains images from my image pool library, when i simulate a program that includes a instance of my second library object the visualization images dont show, any of them, i've checked all the references and tried some options of the image properties but without any difference. Here is the screenshots of the first library (that contains Image Pool) and the second library (that includes images of the image pool first library) and the visualization simulation (with the missing image gif issue). Any idea of what i forgotten in the process? If you need any detail of the library or of the project or you need the library file, ask me, thank on advance

Post by ellocco on XOR with four Inputs with OR-, NON- and AND-Operators ^{CODESYS Forge talk (Post)}
My topic is more of academic nature, I would like to implement an XOR-operation with four inputs on my own (without the predefined XOR-operator) in a function block diagram (FBD). I have two proposals. One works fine and the other one is just an idea, but I do not know, if it is possible to code it in CODESYS V3.5 SP18 in form of a FBD. Here the one that works: And here an idea, which I have not managed to code it as an FBD: Any ideas? Is the 2nd diagram a correct interpretation of the coding task? And is there a way to implement it in form of an FBD in CODESYS V3.5 SP18? Followup (08-Nov-2024): Also in the current version of CODESYS (V3.5SP20Patch3) I have not managed to connect the existing blocks. In the alternative SPS-IDE PLCnext Engineer it is possible.

Post by faceplant on Comparison via CLI is broken ^{CODESYS Forge talk (Post)}
Hello! I am trying to compare 2 projects via the --compare CLI option. In the docs for the --compare option, it describes the usage as .\CODESYS.exe --compare "project path 1" "project path 2". I store my projects in WSL2 on my windows machine. Since CODESYS is happy to open those projects via a path like \\wsl.localhost\home\project.project. So, to compare, I use the command .\CODESYS.exe --compare "\\wsl.localhost\home\prog1.project" "\\wsl.localhost\home\prog2.project". This results in CODESYS just opening the project and starting, not comparing the two projects. No errors are thrown, and I know the paths are correct since I can open both independently in CODESYS, and I can compare them manually through the CODESYS UI. I have also tried moving my projects to the Windows 11 OS and still have the same issue. CODESYS opens the project and does not actually compare them. I am using CODESYS profile v3.5 sp20 patch 1. What is the correct way to compare 2 projects using the --compare CLI option?

Post by imdatatas on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, I have experienced such situations with some servo drive devices in the past. The home completion information is reported to the upper controller by the slave drive with the states of the relevant bits in the StatusWord (for example; 6041h Bit10, Bit12 in Home mode). If the states of these bits are correct in terms of number and state but the motor does not actually perform the action; You can contact the slave drive manufacturer. There may be a problem with the device firmware. Another area you can play around with is looking at the settings in the "Advanced configuration" for Softmotion axis on the page the link to below, and trying it out and using the one that works for you. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cmd_add_softmotion_cia402_axis.html A method I recommended worked for a user as in below message. https://forge.codesys.com/forge/talk/Engineering/thread/40bc82454d/ I hope your problem will be solved as soon as possible and by sharing the result here, you will help others to know and overcome it. Good luck. Best regards, Imdat

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 struccc on The future and proper use of CAA.BOLT, CAA.SEMA,.. ^{CODESYS Forge talk (Post)}
Dear All, Dear CODESYS, I'm curiously following CODESYS transitioning away from the CAA libraries, and I'm mostly in favor of these major changes. Naturally, I'd like to align my current (not end-user) developments accordingly. I'm tracking , reading release notes, ... And want to figure out the future :) Is it possible to hear / read more about the reasons, objectives and scope of these changes? One important element is CAA Types - CAA Types Extern. What is the plan with that? What's the future of CAA.SEMA, CAA.BOLT ? I have never used them (always relied on SysLib*), but they are tempting... Would be useful to have a platform independent "Macro" for this functionality... Is there something in existing or planned ? Are they suitable to be used in low level libraries... For Example IO-Drivers, Components, "to-become system libraries"? CAA.TaskLock, CAA.TaskUnlock ? Well, they don't claim platform independency, so I can't rely on those.... Any up-to-date advise, standard, pattern to follow in new libraries for task and resource locking? Practical set of conditional defines to be used? If this information is not publicly available, can you please send a private message about the proper way to achieve this? I have support agreement, just couldn't get trough with these questions... P.

Post by astutoski on No Motion with SM3_RaspiStepper (GPIO 23/24 Show No Pulses) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m completely new to CODESYS and have been teaching myself. And i Want to control an Axis using SM3RaspiStepper. Following the example on the RaspiStepper home page, I set up an axis through a POU and tied the SMC_StartupDrive (Visu) template to my axis instance (sud). Unfortunately, the motor never moves and I don’t see any pulses on the PULSE pin (GPIO 23). Hardware -Raspberry Pi 4 B -Nema 17 stepper motor -A4988 stepper driver (EN pin permanently tied to GND) Software / Runtime -CODESYS 3.5 SP21 Patch 1 – Raspberry Pi runtime (demo) -SoftMotion in demo mode -Package: SM3_RaspiStepper 0.0.0.6 Axis parameters: Pulse pin GPIO 23 Direction pin GPIO 24 Enable pin 0 (unused) Disable pin 0 (unused) Whether I start the axis from the visualization template or through Online Config Mode, the motor never spins. In Online Config Mode I press Power → the state changes from Standstill to Discrete_Motion, but the motor shaft is still locked and no step pulses appear on GPIO 23 (checked with a scope). I can provide screenshots of the Visualization, PLC logs, or wiring pictures if that helps. Any ideas on what I might be missing? Happy to provide screenshots, project files, or scope captures if that helps. Thanks in advance!
