I tried both 3B en 4. But every time with a lite version. I didn't try the full version of raspberry pi os. Nice to hear you are aware of the problem and trying to fix it. I'll hold on to the image from 2023-10-10 for now.

Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)

Post by dhumphries on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Function blocks in a SFC are executed left to right, top to bottom, instructions in ST are executed from left to right top to bottom as well. I think you are asking about the execution of POUs although you use the name function block, I believe POUs are executed in the order they are shown under the main task.

Can you add a background FB block to the visualization page, and loop through this FB block when the page is in display mode. This FB block requires two more functions, one for executing when the page is displayed and the other for executing when the page is closed.

Hello We started with the new design of Codesys, through a "CODESYS Control Standard S" license. However, after installing the license, connecting, etc. (without any problems), we cannot get the program into the PLC with entries that we have not seen before. Is there anyone who has also experienced this? Better yet, does anyone have the solution?

Post by francescoc on Access to the path *** is denied ^{CODESYS Forge talk (Post)}
Hello, I encountered similar problems, and it appears they were linked to certain add-ons. Resolving this issue turned out to be quite complex. However, we managed to find a solution by downgrading both the "CODESYS Communication" and "CODESYS Recipes" components via the CODESYS Installer, accessible under the "Tools" section.

I'm searching a way to print several projects to PDF, in order to correct student exercises. I'm able to open the printing dialog box using system.commands["print", "print"].execute(). But I can't find the prompt names in order to complete the printing with the dialogs Do you have any way to do that?

Thank you for the response! It's a path I had already considered, however, while it has always worked for me on inputs, it doesn't on outputs, because if I enable the option to update all IOs at every scan, the IO tasks overwrite each other. However, I have found something very interesting which I am posting below.

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Hello, I don't really know what my problem was, but it's working for me at the moment. All i did was to change my code because of some REAL_TO_INT conversions, like i wrote above. And later a complete new Pi setup (because of 64x support with 4.10.0.0 now).

Hello, our team is able to use Raspberry Pi on CODESYS, but we purchased two peripherals that utilize I2C and we cannot figure out how to access these devices in CODESYS. But they are working using Python. Does anyone have a suggestion or an existing library that might help support this? Thank you, Jeff

My experience is that opening pdf file is very dependent on which browser is used. I have tried a couple of them and only Mozilla Firefox has opened file correctly in same screen. All other browsers face some issues. Therefor I had to flip my pdf to txt which has not been nice solution.

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Hello dear colleagues. I have an ESTUN PRONET servo. I'm trying to control via softmotion over the CANopen bus. There is no Ethercat bus in this servo model. In another project,using Ethercat , I controlled four axes. I have problems with ESTUN PRONET servos. A DSP-402 driver mismatch is likely. I would be very grateful for your help in solving this problem.

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi These issues occured using a Raspberry Pi 4. I also repeated the experiment with codesys control for Windows, which results in much lower cycle times. With up to 3 ms, I still think they are fairly high given they should run at 2 ms and don't require complicated kinematics. The effect of higher cycle times for slower movements also prevails.

That definitely does the job with the Ladder Logic Diagram type; fully equipped toolbox. Just starting with Codesys and was following programming steps which explains the choice of ladder I had picked. Thanks for the tip and have a good one! Cheers!
