Post by wayne-riesterer on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Thanks for your responses. I like to write the leanest possible code that I can because it makes it much easier to read/maintain/debug. OR_ELSE is what I was looking for. I wasn't sure if CodeSys short-circuited evaluation and I didn't realize this operator existed. Thanks!

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

Post by arwie on Use MC_Home without enabling the drive for homing method 35 ^{CODESYS Forge talk (Post)}
This is a homing routine which is controlled by setting mode of operation and started by setting a bit in the control word. If MC_Home is not usable for this homing method then I need to implement the same functionality. But how?

hi imdatatas, thanks for your suggestion! I added the process execution to be sure. In the meantime I reïnstall Windows but it dind't help directly. Finally I deleted CodeMeter Runtime Server after Codesys installation. Because this Service was not able to start. And it works (for now) :)!

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.

Good day, I am attempting to use a Waveshare AD/DA precision HAT with RPi 4B+, using Codesys Control for Rpi. The waveshare hat uses SPI. I am successfully using the RPi GPIO (inputs and outputs) but do not know how to access the AD/DA channels. Any help would be appreciated.

Post by mqi2r on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
For anyone with this issue, you may need to: Open the text list properties (right-click the text list once you create it). Select the Text List tab. Change the Download by option to Visualization. I was fighting this for so long. Once you do that, you should find your text list appears in the drop down when editing a visualisation.

Post by wagokurt on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
I have installed both the Codesys Control for Linux SL 4.16.0.0 and Target Visu for Linux 4.16.0.0 packages in Codesys 3.5 SP21 Patch2. When I try to add a target visu, it is missing. I have spent hours on this and tried different machines, all behave the same way. Is this a bug?

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Thanks Tim. I would think it somehow is relevant when creating a compiled library, but that may very well not be the case. If I understand you correctly, then the same compiled library created from my source code would work for both 32 bit as well as 64 bit controllers.

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!

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.

Post by anderson on function block output ^{CODESYS Forge talk (Post)}
so it is not possible for me to use the function blocks and through them I can select the digital outputs of the PLC so that pulses and direction are output, or some function block that does this reading and in it I can program the pulse and direction outputs for the drive?

Post by as1984 on Codesys Control log "eventbuffer full" ^{CODESYS Forge talk (Post)}
Have you found a solution for this? Id be thankful for every hint. I have a controller with the same events in log and sometimes it crashes. Memory of the codesys3 task rises until the linux system kills the task because the controller runs out of memory.

Hello, I am extremely new to using codesys. I have an IFM CR1102 HMI with physical buttons on the right side. I need to have these buttons toggle which visualization is active. I currently have ladder logic for when the button is pressed just need the action side for setting the active visualization. Any help is appreciated.

Hey there! Is it possible to download the "CODESYS Scripting" package outside of the "CODESYS Installer"? Or is there a alternative way to download the python files for the scripting engine? I want to setup a test environment to write test scripts and therefore want to have those python scripts for e.g. autocompletion. Thanks in advance!

Hi All, I finally figured out how to solve it. The only away that I got it to work was to define parity to None on modbus configuration, and now works like a charm. Just for the record I'm using the GPIO port pins (8,10) and a RS485 to ttl shield that you can find online. Thanks all for the support! Regards Ricardo

yocto isn't the part. which architecture you are using? arm, x86, 32bit?, 64bit? normally u can use the deliveral from store and integrate it into yocto. for resolv the dependencies, its best way todo using an recipe and let yocto do prebuildchecks jefore the install-commands

Hi, gseidel. Thank you so much for your advice. I have created a program to preprocess G-code as follows 1.SMC_ReadNCFile2 2.SMC_Interpreter 3.SMC_CheckVelocities Then I put SMC_OUT_QUEUE in SMC_Interpolator. Where should I insert SMC_SmoothMerge and SMC_SmoothPath? Or are there any example link for it ?

Thank you for your answer! I'm not sure, but it seems this is not what I am looking for. I attached three pictures. The first one is from the Codesys IDE. I use an Information Model to generate an OPC-UA server. I connected via UA-Expert, and there I see the URIs I would like to change.

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved
