Bitmap Image (outlined in Red in attachment) with it’s configure window open in Codesys 2.3.9.55. Image doesn’t show-up in on-line Web Visu (this project only). No problem with bitmap images in all other codesys 2.3 projects. Web visu in Internet Explorer since 2.3 Web visualizations don't work in Edge.

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?

I continue this topic by myself, I'm very happy with the Codesys support / community ;-) This information (Download time) should be stored in the compileinfo : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_load.html But the file is not text-readable (see attached file) so how to solve if download time is empty?

In my project, I have frames that I would like to read the current active index. I change the frame index using the onclick properties of a button, then change frame index. I need to do some logic based on which frame index is selected. Is there a way to read the current active index of a frame?

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 timvh on PHOENIX CONTACT Axioline PLCnext project in CodeSys SodftPLC ^{CODESYS Forge talk (Post)}
1) Based on your first screenshot. Do NOT filter on "Phoenix". Then first select the Ethernet adapter (of CODESYS) and add this to your device. 2) Then to this Ethernet adapter add a Profinet Controller of CODESYS. 3) Then to this Profinet Controller, add your Phoenix Profinet coupler/adapter.

Thank you Pernockham, I am using Windows SoftPLC and the device is CODESYS Control Win V3 x64. In the above attached example, the file is Linux-based. This is an external add-on file in the CODESYS installer (CODESYS Control for PLCnext SL). I am trying to implement it without this add-on file.

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Hi, I’m evaluating CODESYS for our devices. If I buy a standard runtime and the Toolkit, can I create a custom device descriptor so users can select my device (instead of just “CODESYS Control for Linux ARM64 SL”) when starting a new project? Has anyone done this or know if it’s possible? Thanks!

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.
