Post by reinier-geers on License problem gateway ^{CODESYS Forge talk (Post)}
The hole setup is made by 3s. So its a comination of one not two. If Epis decide not to support extra licence whats then the funtion of providing an option with a single license ?? So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I'm getting closer to the error. The combination of STRUCT and ARRAY probably causes the strange behavior. As soon as the ARRAY is followed by a variable, the problem arises. Examples: X: ARRAY[1..2] OF INT; // okay Y: ARRAY[1..2] OF STRUCT; // problem Z: STRUCT; Z.ArrayOfInt[1]; // okay Z.ArrayOfStruct[1].Variable // problem // *update - array of array also causes the error A: ARRAY[1..2] OF ARRAY[1..4] OF BOOL; // problem I can't be the only one who has this problem. Or? Maybe there is a solution. Anyone? Or is it a bug after all?

Post by c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Post by shafiq-dsc on Beckhoff EK series cannot detect but BK1120 detect ^{CODESYS Forge talk (Post)}
Dear Support, I have i950 wants to connect with Beckhoff EtherCAT coupler BK1120. There are 2 GSD files for BK1120. 1. BK1120 without MDP.(EtherCAT ESI Device Description (XML)) 2. BK1120 with MDP. (EtherCAT BKxxx (MDP) configuration files) When connecting the BK1120 with i950, scanned devices detects BK1120 without MDP from ESI No1 above. But the KL1408 & KL2408 not detect because they have ELxxxx IO type. When manually insert BK1120 with MDP, the KL1xx8 is able to add manually also but the error shows and Install Missing Descriptions appears. The questions; 1. Why the error occurs? 2. Can the i950 connect with KLxxxx IO type or not? Regards, Shafiq

Post by struccc on Request a dark mode for CODESYS ^{CODESYS Forge talk (Post)}
😁 Yes, exactly... I have a clue about the why not... But really, it was many years, releases ago... Agree, this is not a functionality customers would pay for, but it's one rendering the product cool and contemporary. Like many other "simple" features like: Opening multiple projects within the same IDE Not just attaching, but editing diverse files inside the IDE (like XML, TXT, SVG?) Use 3rd, CODESYS independent plugins, editors inside the IDE... Isn't it possible to integrate CODESYS Engineering under VS? Or just use the core functionality from VS? Or the LINUX guys have a better idea?

thank you very much! I found the generate_code methode, but struggled with the primary and active_application. With this expample I will be able to play around. If the code generation takes a minute or more I often switch to other programs and don't notify the process is finished. So now I'll get an alert and will switch back immediately. My next little project will be, to beep different if there are errors and a seperate script to do the download incl. the user management data base without stopping at the dialogs asking for onlinechange/complete download and overwriting an existing database and as goody, play a beep/sound again.

Epis doesnt want Softmotion. I thought it was about the price. If it was possible it would be working already and i dont need an extra licence. Thats the problem of codesys. The software is running but hangs on its license. Epis made it posible to see the stick. I can see the license. Softmotion is there from 3.5.14.Xx Like is said And Motion control is alrady posible 15 year ago. And i only need a Sync of 2 drives. I want a good solution not a refund. Dont point to the manufacturer. The software is made by 3s not by epis .

Post by westcountryewe on Persistence Variables missing and DO NOT retain from Persistence Channel when using Boot Application ^{CODESYS Forge talk (Post)}
We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise the Boot Application method because of logistical restrictions of being able to get out to every site, so at the moment it's a bit restriction.

Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap. Please, if applicable, update these instructions.

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge talk (Post)}
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

Post by brubingh on Download Missing Libraries not working ^{CODESYS Forge talk (Post)}
We are working on a project and the customer required 3.5.16 BF4. After working on the project for a few weeks I opened it the next morning and it could not access libraries. IecVarAccess could not be accessed. I checked if windows updated - it did not. So no explanation for why it lost access other than that I shut down the computer for the night. Note that I am using a demo license. I still haven't figured out any reason to purchase a license. So I spent the next hour reinstalling CodeSys. Note that I did NOT uninstall first. After install I waited another 5 minutes for it to open the first time. I clicked File->Open to open the project. Previously I had selected File->Recent Projects - not sure if that makes and difference. But after this process it did open the project and compile it just fine. This is miserable. If this had happened when I went on site to a customer I would have lost hours of work doing the reinstall. Is there a different and quicker fix?

Hi everybody, I am looking for a solution to send files, for example, to an ftp or a cloud. I can't use oscat library because 64 bit controller are not supported. Therefore, I see that the IIoT library has some functions that might help me to implement this sending process in codesys. Does anyone have any examples of how to do this? I have spent some days with this issue without success. Best regards.

Post by smartcoco on Request a dark mode for CODESYS ^{CODESYS Forge talk (Post)}
CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.

Hi, there is a plethora of hardware available for it to be succesful on. In theory every ARM32/64 or x86/64 device is a potential target. Next to this there are embedded device platforms for which specific toolchains are available. A good starting for manufactureres of CODESYS capable devices is available here: https://www.codesys.com/the-system/codesys-inside.html. That should give you a good reference point.
