Post by eschwellinger on Bibliothek: floatingpointutils ^{CODESYS Forge talk (Post)}
naja die compiled library hast du ja - du hast halt eine exception - und dann wirst du gefragt ob du das ganze Debuggen willst. Die offene Bibliothek wirst du nicht bekommen - daher würde ich so vorgehen: Dein Projekt hier mal anhängen so das man mal draufschauen was du genau aufrufst und wie.

Post by lbartik on MPC predictive control ^{CODESYS Forge talk (Post)}
Would this work? https://www.mathworks.com/hardware-support/codesys.html I'm also interested in real-world MPC and have no idea where to start. There is an exciting Python library that is also beyond my grasp: https://www.do-mpc.com/en/latest/index.html Step 1, get PhD(s). Step 2, get job in aerospace/robotics. Step 3, return 15 years later to share this knowledge?

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
yes i took the library from another forum: https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/, it is made for the ads1115 but the ads1015 is almost the same device with same adresses i only changed the divide value of the analog value, because thats the only difference between the ads1115 and ads1015.

Post by rafaelbrito on Integration C Code ^{CODESYS Forge talk (Post)}
I tried to use C code in the library that I have been developing in the project, but without success. I tried to use the CODESYS Control SL Extension Package to generate XXXdep.h and XXXltf.h, but without success. Do you have a better example of how to generate these files and how to compile them?

Thank you, very useful information. I did a library for serial communication and could not understand the reason only 256 chars could be read (after sending more than 256). Following your suggestion, I can now send any number of chars and everything will be received.

What version of Windows are you using? If you are using older Windows, just upgrade to the latest version and use CodeSys IDE as usual. Nothing will happen.

It would be great if there was a thread that had some quick-start links for basic how-to. But one that advanced programmers can jump into. I found this video playlist by SoftMotion-Black, which was very, very helpful: https://www.youtube.com/playlist?list=PLkc8m2OD0r9xJyfTiCBb1vuU_d2yBhjZ_ This person has some other great vids like creating your own custom library, which is awesome for OEMS.

Hello, Working in 3.5 SP11 32 bit and using the 3S CANopenSafety Slave 3.5.11.0 library on an IFM CR711S. The 3SCSSD.CANOpenDevicesSIL2 function block keeps throwing "UNSAFESTACK_NOT_OPERATIONAL" Additionally, the Status of the device gives "There was an error accessing an I/O parameter". Any ideas on where my issues may lay? I have not found any good documentation that would explain the issue.

I am struggling with this issue right now (again). I have nested structures with configurable array sizes. In the past I ever used parameter list. Very easy way! As of now I cannot find any solution. Ridiculous that they deprecated it without an alternative solution.

Post by onstage on Unable to add EL6751 to Control RTE V3 on W11 IoT LTSC using Eng. V3.5 SP21 ^{CODESYS Forge talk (Post)}
For reference, it was just me being unfamiliar with EtherCAT in CoDeSys. Anyone with knowledge who would have opened the ScanResult screenshot would have identified that the preceding EK1100 was the device missing in the library. Bottom line - Do something else for a while and then get back at it with fresh eyes!

Hi liai, is it possible, that SM3_Basic is missing in the library manager? (It should be inserted automatically when adding a Cam table, along with the other motion libs.) You can add it manually and see if that solves the compile errors. Best regards, Georg

Ich bin leider auch über den Fehler gestolpert, aber selbst in Version 3.5.19.50 ist dieser noch enthalten. Bis 3.5.19.20 kann ich meine Programme noch nutzen. Ab 3.5.19.30 ist der Fehler anscheinend vorhanden. Ich habe leider auch schon einen Haufen Programme mit meiner Library erstellt, somit wäre ein umbenennen nur mit sehr viel aufwand möglich.

Post by timvh on Sysfile inuts ^{CODESYS Forge talk (Post)}
To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.

Post by masmith1553 on SDO generation ^{CODESYS Forge talk (Post)}
If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Hi Martin, I got the messagekey of the "upgrade format warning dialog" with key:"<< No Key>>". (please refer to the attachment) Is that means i can't use system.prompt_answers["<<No Key>>"] = PromptResult.OK; to auto-answer 'OK' in this dialog? Is there any other way to auto-answer this dialog? Thanks!

Today I was struggling with the same problem. in search for a solution i found this thread. Then i tried some things. It doesn't seem to be just a libraries' fault. In addition to 3.5.19, we also have a 3.5.18 version installed, the library versions of Modbus_TCP_Master and Modbus_TCP_Slave are the same, but more than 10 slave channels can be added in 3.5.18

Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.
