Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hello, We have a problem with CodeSys on a raspbery pi with an ADS1015 analog to I2C module. It can't find the I2C device on the i2c bus, it says No I2C Driver Found. When we use the RPI terminal we can find the I2C device and read it out. The i2c-1 bus is also accessible from codesys. The device address of the Analog to I2C module is 0x48. Can someone have a look what the problem is? i submitted the screenshots in the attachments. i also include the device description and library.

I have the following setup: Proxmox PC with a debian 13 VM running CODESYS Control Linux SL and Edge Gateway. Installation method was through the Deploy Control SL and went rather smoothly. In my Device Tab I find the gateway and when scanning my network I also find my runtime. I want to connect and get promted that I should add a user. After setting up the user I get an error saying, that the device is not responding my scanrequest. Deploy Control SL Operation saying everythings up and running. I can confirm that from the terminal on the VM with "systemctl status codesyscontrol" and "systemctl status codesysgateway". I am running out of ideas how to fix that issue. Can anybody help? Screenshots attached.

Post by joep on overruling kinematic limits of [-90°, 90°] in bipod_rotary ^{CODESYS Forge talk (Post)}
Hi All, for my robotics application we are building a 2-axis parallel scara using the kin_bipod_rotary kinematics. Codesys implemented limits of [-90°, 90°] according to the documentation: https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Positioning-Kinematics/Parallel-Systems/Kin_Bipod_Rotary.html Would it be possible to overrule these limits somehow, our mechanical limits are more in the range of [-110°, 135°] In this range we also don't encounter point where singularity is an issue. Hopeful someone knows a solution, Best regards, Joep

Post by rodberna on Library for arrays ^{CODESYS Forge talk (Post)}
Hi, I'm creating a program where I need to handle arrays, like: - Declare lenght variable arrays - [array(1..var) of "sometype"]. This is not possible in pure codesys, right? - Know array lenght, min, max, avg values in runtime - append/delete itens in an array - and so on Is there a library know for this in codesys. Is it possible to build our own libraries using some high level language like python or java script?

Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Post by timvh on library is not available ^{CODESYS Forge talk (Post)}
1) In the library manager of your project select "Download missing libraries". 2) In the library manager open the "Placeholders" dialog. In here find the Placeholder which is not referenced to a specific library yet. Click in this line on the Library column and select the latest version of this library.

Post by davidking on Error, visualisation property handling, VISU_USEPROPERTYINFO ^{CODESYS Forge talk (Post)}
Solution: Disable VISU_USEPROPERTYINFO define Go to Project → Options (or Project → Properties, depending on your CODESYS version). Find the section called Compiler Defines. Look for the define: nginx Copy Edit VISU_USEPROPERTYINFO Delete it from the list, or uncheck it if it’s a checkbox. Save your changes and try compiling the project again. → This is the right approach if you don’t need property handling for visualization elements.

You get fewer tools when you create a new POU and choose ladder diagram instead of ladder logic diagram. Create a new POU and select ladder logic diagram and you should find the additional tools you are looking for in the toolbox.

Many industrial systems are now using Cloud SCADA architectures for centralized energy management, remote dashboards, and operational analytics. ATSCADA iEnergy Tools supports: Real-time energy monitoring Historical data logging MySQL integration Reporting and Excel export Remote SCADA dashboards Cloud-based monitoring systems I think this type of solution is practical for factories, power monitoring applications, building management systems, and other industrial automation projects where energy optimization is becoming increasingly important.
