Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Ok, with debug you suppress the errors, but that doesn't help you any further. You can find information about the missing drivers here https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/ and here https://github.com/stefandreyer/I2C-Multiplex I'll have to have another look at which library you need. But you can easily find out. Create a completely empty project and insert the TCA9548. You don't need the board. Then look in the library and resolve all conflicts If you can compile the project without errors, delete the TCA9548 and insert the ADS1115. The driver should then also run. Small bonus: with the TCA9548 you can expand your network as you wish and use identical sensors multiple times

Post by gatto on Undertanding Application Based Licenses ^{CODESYS Forge talk (Post)}
Hi, i think you are right. Did you press the key shopping cart? Codesys tells you the license. What I don't appreciate is that i need an additional license for communication. The system reports opc ua but this cheats you. This is communication that also concerns the tag symbols that codesys eth v3 exchanges with an operator panel. Attached is a screenshot of my case where you can see that communication opc ua is cheating you. 512 tags included in the program license are few. So, I had to buy 2 licenses. one for the program and one for communication. I don't like this policy.

Post by struccc on Request a dark mode for CODESYS ^{CODESYS Forge talk (Post)}
😁 Yes, exactly... I have a clue about the why not... But really, it was many years, releases ago... Agree, this is not a functionality customers would pay for, but it's one rendering the product cool and contemporary. Like many other "simple" features like: Opening multiple projects within the same IDE Not just attaching, but editing diverse files inside the IDE (like XML, TXT, SVG?) Use 3rd, CODESYS independent plugins, editors inside the IDE... Isn't it possible to integrate CODESYS Engineering under VS? Or just use the core functionality from VS? Or the LINUX guys have a better idea?

Post by pistola on Error during Updating the Visualisation ^{CODESYS Forge talk (Post)}
I've got a visualization I'm working on with some rectangles and lines. When I simulate the program I get an Error and Message in my message box, "Error during Updating the Visualisation:" and "Overflow error." Any ideas on how to fix this? I only have 70 elements total for this visualization. I am using absolute movement for a few of the elements, would this cause the issue? The visualization seemed fine before I added these movement elements, but there is only 7 that move, that doesn't seem like it should over load the system. I am currently testing using simulation so I'm not sure if that has an effect either. I tried looking in the codesys help manual and couldn't find anything referencing this.

Or you need to modify the file codesyscontrol.cfg for change path permission, but this is another history Buone feste !

Post by gseidel on Beckhoff AS1060 and EL7041 configuration ^{CODESYS Forge talk (Post)}
Hi pmanuele, while I don't have firsthand experience with the EL7041 and the step motor AS1060, there are two things you can check: If you use an external encoder, please make sure you use the alternative device description calles "EL7041 1Ch. Stepper motor output stage (50V, 5A) Rev24 with external Encoder". The SoftMotion driver will set the feedback type automatically, and use the correct object for the actual position (16#6010:21 instead of 16#6010:20) If you have problems with changing the controller mode, I assume to velocity, please make sure you change the PDO mapping so that the actual velocity (16#6020:33) and set velocity (16#7010:33) are mapped by PDO. Hope this helps, Georg

Post by trusty-squire on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hi, Is there a way to read the homed status from the EtherCAT drive directly? I am currently flagging the homed status on the succesful completion of the MC_Home function block, but I have had false triggers where the drive didn't actually execute the homing procedure but the MC_Home FB is marked as complete without error. I looked at other MC/SMC function blocks but the closest I can find is the "Homing" bit from MC_ReadStatus FB, but this doesn't show if the drive is succesfully homed, only that it's homing. Any guidance is welcome. Thanks!

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I got this working using OPC UA. In the logic application I just added a Symbol Configuration. In the HMI application I added a Data Sources Manager and OPC UA Data Source. The one thing I don't like is the way the tags end up being named in the HMI application. In the logic application I have a program named PLC_PRG. It has a variable named testDINT. In the logic application the name I get for this variable is DeviceSet.CODESYS_Control_Win_V3_x64.Resources.Logic.Programs.PLC_PRG.testDINT. This is very long and looks like it could change if I used this on a different device type. Any ideas how I could get this name shortened down to just PLC_PRG.testDINT like it is on the Logic application?

Post by r-c-r on SM3RaspiStepper 0.0.0.6 issue ^{CODESYS Forge talk (Post)}
Hello, I noticed that version 0.0.0.6 is now available, so I tested it using CODESYS V3.5 SP19 Patch 7 and SoftMotion 4.17.0.0. While the project compiles and downloads without issues, I encountered a problem with the 'Enable: GPIO pin number that is set when the axis is enabled (with MC_Power) (0: not used)' functionality — it no longer works (HIGH level not present at the output pin). I observed the same behavior with version 0.0.0.5, whereas version 0.0.0.4 functions correctly. Could you help me identify what might be causing this issue or suggest how to resolve it? Thanks.

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge talk (Post)}
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

As soon as the PLC CPU is restarted, the Ethernet port is OK, but the TCP Server displays an "UNDEFINED" error. I can't reset the error using the diagnostic confirmation or the "mbserver.xConfirmError" bit. I noticed that the error only appears in the "mbserver.byModbusError" memory and the description is "UNDEFINED." The "mbserver.xError" memory doesn't flag an error. When using the warm restart function and then START CPU, the devices return to normal operation. The following demonstration images; The main question is: How can I make devices boot automatically?

Hello, I am having trouble figuring out the proper location for my virtual runtime to create a .CSV file. No matter the file location I set, I get error 14 (CANNOT_OPEN_DIRECTORY). I have tried multiple different file paths ('/', '/var/opt/codesysvcontrol/PlcLogic', '/var/opt/codesys/'). I understand that there is only certain places that Codesys can read/write. I am also running this virtual runtime in a Podman container. Does anyone know what the location should be? I attached the archive I was using, a project that tests CSV capability that I borrowed from someone else. Thanks!

After creating a new project, i choose the device "Opus B3-B4-B6-3.5.19.50" that is already available in my version of codesys, but i think the problem is that my version of codesys or something else is not the same as the codesys runtime version running on my display. Can anyone tell me how i can see the codesys runtime version on my display? i tried looking in the settings (Daemon > CDS) on the display, but all i see is "N/A" for "Customer Number", "Customer Part Number" and "Customer Serial Number".

Post by mark on IO link on IFM AL133x only single digital input on a channel ^{CODESYS Forge talk (Post)}
I have a problem with the CODESYS IO-Link SL software. When I insert a IO link master AL1332 and plug a discrete digital input to a channel it reads only 1 of the 2 available inputs on that channel. Is there anyone who sorted out if the second input is also usable? When we configure the module without the CODESYS IO-Link SL software then the second input on the channel can be used. At the moment we use some channels on a module as IO-link port, and some as discrete IO. It would be very nice if we can use both inputs on a channel with the use of CODESYS IO-Link SL.

Hardware version or firmware version not supported! (-7, 0x00000BB8, 0xFFFFFFFB) Whats wrong with it?!?!? I read a lot about the issue in topics from 2020-2021 but it always was stated with new Codesys control version issue will be fixed (4.4 for example) but still it is there.
