Post by elsmart on How to create custom visualisation components (widgets)? ^{CODESYS Forge talk (Post)}
Hello I'm currently working on a project where I need to implement visualisation in Codesys on Raspberry Pi via web browser. I'm uing Codesys IDE V. 3.5 and I was able to successfully run my program and visualisation using generic elements provided by Codesys on Raspberry Pi Compute Module 4. However I am dissatisifed by the limiations and looks of generic elements. I would like to create my own components for this specific task (like cyclic buffer with messege boxes or matrix of data structures). How do people develop their own visualisation components in Codesys and how to implement them in a project?

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 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 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!

If you use LTIME() you will be very accurate and be able to have a normal task cycle time.
