Post by rov-dk on Professional Developer Edition (git): Invalid URI ^{CODESYS Forge talk (Post)}
Hi All, I'm using git (1.4.0.0) in CoDeSys (Rexroth ctrlX 3.4 / CoDeSys 3.5.20.30). Every time I click on a modified file in the "Git Status & Staging" view I get the message out of attached file. I do not find any hint: Does anybody have an idea what the cause is? Thanks in advance.

the Answer is easy, you don't reapecting the codesys-behaviour and pre-request on a dll/so like you like to create. codesys won't load it about the fact that the dll isn't registered in codesys. check this page for more informations: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_extension_extension_sdk.html

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.

IT updated a group policy that caused this issue. We resolved by going to Local Group Policy Editor > Local Computer Policy > Computer Configuration > Windows Settings> Security Settings > Local Policies > Security Options. Set "System Cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" to DISABLED

Post by laurits on Max lines of code, codesys CNC ? ^{CODESYS Forge talk (Post)}
Testing Codesys CNC. SMC Interpolator Throws me an error if my code surpass approximately 32000 lines of code. (SMC_CNC_INTERNAL_ERROR) What is the max lines of code SMC Interpoltor can handle ? I've been thinking breaking the code up into smaller sections, but that gives me a lot problems later if i want to use "Blocksearch" etc. I need to run approximately 2000000 lines of code.

I am trying to create multiple branches in my project and I keep getting gaps in the ladder logic "wiring". I'm not sure if this is a graphical error or something else but every thing I've tried to do to correct it does not work. Has anyone else run into this or know how to correct it?

Post by zoppp on Visu Frame-configuration___text will not work ^{CODESYS Forge talk (Post)}
Yup, I've been having the exact same issue. A workaround that was working until Visu 4.8.0.0 was using TextList as the type in the frame configuration and then wrapping the text in quotes when configuring it. Im not sure if it will work with variables and I know it does not work if the type is text.

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.

It seems that the hmi sl license only works with windows. If i'm happy using web visu, rather than target visu, is possible to use remote opc-ua remote alarms without the hmi sl? Maybe it can be included in a different license that works on Linux? thanks

Post by timvh on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
If you want to use the Test Manager, I prefer to start all the tests through the scripts of this manager. So open from there the projects, load it and run it. If you also want to use Python scripts to access CODESYS functionality, while executing a Test Manager script, then also start them from the Test Manager commands.

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?

There has been a fix in SP21. I tried it in this version with the option "Use unicodestring" enabled in the Visualization Manager and it worked if the variables used for the function are declared as WSTRING variables wsFormat : WSTRING := "%t[HH:mm:ss dd.MM.yyyy]"; wsTime : WSTRING; IECStringUtils.FormatDateTime(cbpResult := ADR(wsTime), uiResultCapacity := SIZEOF(wsTime), cbpFormat := ADR(wsFormat));

Now, for CODESYS v3.5 SP21 I can no longer find the "OPC UA Information Model Repository" entry to add as a command. In the "Tools" menu it is listed but greyed out, reporting "Plug-in is not available". So how do I add the Plug-in?

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 CODESYS Visualization M License Fails to activate on Linux SL <sup>CODESYS Forge talk (Post)</sup>
The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!

Post by sandro66 on Application-based license Modbus Channels <sup>CODESYS Forge talk (Post)</sup>
Hi, I imported an old project created with version 3.51.20.50 into the new version 3.51.21.20. I'm using ModbusFB.ClientTCP v4.5.0.0. Strangely, I can no longer download the project due to a licensing issue I didn't have before. The number of Modbus channels has gone from 1 to 54!, and there's no license that would work. Can anyone tell me where I'm going wrong? Thanks Sandro

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers <sup>CODESYS Forge talk (Post)</sup>
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.
