Post by bjohnson on CODESYS and Win10 - "the version profile is not valid" error ^{CODESYS Forge talk (Post)}
We just had this problem today when our IT updated a group policy. You need to go 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.

Post by naduley on Multiple Branches ^{CODESYS Forge talk (Post)}
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?

ich meine mich zu erinnern, dass ich schon FB's hatte, die Fehlermeldungen mit löschen des Enable/Execute Bits abgelöscht haben. Dann würde bei dir sobald das Error Bit gesetzt wird, nichts mehr drin stehen. Vielleicht wäre es ein Versuch wert, den String vor dem zurücksetzen des Execute in eine Variable zu speichern, ob dann was drin steht und danach erst ablöschen?

Post by ulad on SPI Communication ^{CODESYS Forge talk (Post)}
Hello. I created a project that uses SPI. This project is working well. I can see with an oscilloscope that the SPI pins are actually changing. But when I resave this project in the IDE and open it later in the system, I see a constant error. What do I need to fix? What am I doing wrong? Thank you.

Post by eschwellinger on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
The "remove unused" parameters have been added to 1.0 version as well as the "manual" removal of pins... also allowed "empty" inputs for blocks is in and the compile error described there should no longer occurs. Drag drop of variables is not yet implemented and I don't think the double-click feature yet either.

please tell us the exact error message from diagnostic. U can view it at devicetree in the node-element diagnostic from modbus-configuration. u also can activate the function auto-reconnect in master and increase a little bit the timeout and the repetition to male thw communication a little bit more robust

Post by davidbo on i2c How does CODESYS handle exception or error messages. ^{CODESYS Forge talk (Post)}
For Raspberry Pi I have made a python script which regularly read a bulk of data over the ic2 from a device. Sometimes I get an Exception an IOError. I assume similar things can happen in CODESYS. So how does CODESYS handle that? Can I get any info about such an event?

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

Hey schnepper, when i look into your c-file, i would say that only the main-function is declared with cext-addendum in your codesys-library-project. all yöur funtions in library has to be the cext-addendum when the external implementation is activ. if i remeber right, methods and other subelements dont need that, but every base-elements

I have not used this client / server OPC UA combination since. We were only making some kind of proof of concept. I did understand that there could be some kind of bug. I do not know if the supposed bug has been resoved since. Perhaps you could try what piautomation is suggesting

I have some errors as you can see in the picture when i build the project. I have not been able to trace back to the error and i have no idea where to look at to fix this issue. What is GVL_Io? Is it related to some library?

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger yes I have been using xDoubleStorage It happened again and I checked and the files were still there with there contents, restarting codesys or rebooting would not even reload them. Doing a download and then starting the PLC loaded them and began working again. Some sort of mismatch error or something?

I added a main action to an SFC step, and then tried to delete it. There is no delete option in the SFC menu nor in the right click menu of the step. I deleted the action from the device tree, but building results in and error saying the action is not defined. Is there a way to delete a main action?

Hello, I'm using th IDE Combivis studio 6 (codesys based) and I get an error message when I use IO-link. "The license is missing or invalid. The API is running in demo mode." However the package Manager indicates that no licence is required. It used to work, it seems that the free package has become a paying one. Can Codeys confirm this? BR
