Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

Maybe your slave device didn't properly closed its socket port and CODESYS is unable to reconnect? Did you restart your slave device?

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Follow up question: in the Project Settings, under Library Development, there is an option related to this: Check all Pool Objects -> Pointer size to use Options are: * 32 Bit * 64 Bit * 32 and 64 Bit The descriptions and online help suggest to me this is only relevant for checking and showing any incorrect pointer types as an error in the IDE. E.g. using a DWORD to store a pointer value on a 64-bit controller. It would not control the creation of either 32-bit or 64-bit compiled libraries. Is that correct?

Post by durallymax on Persistent Vars ^{CODESYS Forge talk (Post)}
Looking for a better way to manage Persistent Variables. We tend to have local vars in our FBs that need persistence through downloads as the systems are updated/altered on a regular basis. Retain would suffice if we had an easy mechanism to backup and restore like we can with Persistent variables and recipes. Although not having to remember that step with Persistent variables is preferred. We're running into issues with persistent storage capacity (WAGO PFC200) using the Persistent variable list (and adding all instances). It appears there are many ways to handle this, some with recipes, some with files, others with application manager. Is there a solution that exists that is as simple as declaring as Persistent and managing elsewhere? Or do we need to move onto periodically writing CSVs?

Post by ranadheer on Implementation of IEC-104 ^{CODESYS Forge talk (Post)}
Hi Everyone, As we didn't have client for IEC - 104 - only server server is available , so because of that we are trying to make establish the communication between the external simulator as a Client and codesys itself as a server. We are looking for the variable behavior from CODESYS has to change according to the message triggered by the CLIENT (we are using simulator Application like Redisant). We are able to see the log data as the status of triggering the SCS from Client received to the Log data of the codesys device(attached screen shot of it) and in simulator panel we had set the details to trigger the data from Redisant to Codesys. Current Status: The project builds and runs successfully, but I need guidance on how to connect this to an external IEC-104 simulator for testing and visualization by using demo mode.

you could try to uninstall 4.8.0.0 Package by the CODESYS installer - and reinstall (I would use current version) - this should solve it

Post by budd7566 on Text size suddenly changed ^{CODESYS Forge talk (Post)}
Iv been working with a Deep Sea Electronics DSE840 for about 6 months. I have a development version of my program working with a state machine and a basic gui interface. I went to implement CAN and suddenly the text on the gui on the controller is much larger than before. I could flash old versions of my project and the text was the correct size, but if i renamed the project file, the text displayed would be large. The visualization in CODESYS always shows the expected size, but not the controller. I did a fresh install of CODESYS and even a new project with only one text box, I cant get the text size on the controller to match what is displayed in codesys to match. Any advice?

Post by snhatton on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Good afternoon, After changing the security settings to: CommunicationPolicy: POLICY_BASICSHA256SHA256 CommunicationMode: ALL Activation: Activated UserAuthentication: ENABLED Then generate a new certificate on the device for the OPC-UA server from Security Agent->Device->OPC UA Server. Restart the runtime using tools->Update Raspberry Pi->Stop->Start for the changes to take effect. It may take a minute for the runtime to start. Initiate the connection from the UA server side. You should see a pop-up asking you to trust the certificate. Click on the button 'Trust Server Certificate'. Next, you should see a certificate in the quarantined folder of the security agent in CODESYS. Click and drag this from quarantined to trusted and then try connecting from UA expert to the device. These steps worked for me and my setup and I hope they can help you!
