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 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 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 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?

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) :)!

How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

Hi. Raspberry pi 4 runtime. Runtime version 4.16, IDE version 3.5.21. Is it possible write new value for variable via modbus tcp or serial devices when both enabled? As I see - not. What can I do? It is terrible restriction.

Post by timvh on IECStringUtils.FormatDateTime ^{CODESYS Forge talk (Post)}
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));

Hello everyone, does anyone know what this error means: Internal Error in code generation for http://opcfoundation.org/UA/DI/: Dimensions must be empty. I use the standard information models from Codesys and haven't even called the Information Model, but my program can't compile. the only thing I did was to insert the Communication Manage.

To change the current visualization for (all) webclients: Add the library “Visu Utils” and use the following example code: VAR xChangeVisu: BOOL; fbChangeVisu : VU.FbChangeVisu; END_VAR // Change to Visu2 when setting xChangeVisu to TRUE fbChangeVisu( xExecute:= xChangeVisu, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, //itfFilter, eError=> , sVisuName:= 'Visu2'); IF fbChangeVisu.xDone OR fbChangeVisu.xError THEN xChangeVisu := FALSE; END_IF

Post by davemansell on explicit cast ENUM to UINT and vice versa ^{CODESYS Forge talk (Post)}
This is from sometime ago but below might help someone else; this could be done via POINTERS. Make sure you protect for NULL pointers etc if you take this approach. // DECLARATION myEnumValue : enumMyEnum; u8 : USINT; pmyEnumValue : POINTER TO enumMyEnum; pu8 : POINTER TO USINT; // CODE pu8 := ADR(u8); pmyEnumValue := pu8; myEnumValue := pmyEnumValue^; // dereference the pointer

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.

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!

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.

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Post by gseidel on can not new a cam table in codesys V3.5 SP20 <sup>CODESYS Forge talk (Post)</sup>
Hi liai, is it possible, that SM3_Basic is missing in the library manager? (It should be inserted automatically when adding a Cam table, along with the other motion libs.) You can add it manually and see if that solves the compile errors. Best regards, Georg

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

You can change the node id by adding the following to /etc/CODESYSControl.cfg: [CmpOPCUAProviderIecVarAccess] CustomNodeName=MyPLC123 Then restart the runtime and the new Node name will appear with the connection. I don't know if it's possible to remove the |var| from the name. I hope this helps!
