Post by mqi2r on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
For anyone with this issue, you may need to: Open the text list properties (right-click the text list once you create it). Select the Text List tab. Change the Download by option to Visualization. I was fighting this for so long. Once you do that, you should find your text list appears in the drop down when editing a visualisation.

Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.

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.

If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Hi, thanks a lot for the response. I did check all these parameters, but if the PlanningTask takes up to 60 ms, I can't increase the Buffer to such values. I contacted the Codesys support with a projectarchive. Let's see if they can help. Thanks again for your great support!

Hello Jusito, Can you share your final code, please ? I tried to implement a similar feature (going online, doing the reset and the start). But I get a timeout on the reset/start when I'm testing the script. If you got something working, I would appreciate to see it.

Took me a while to work on this again. I testes today with a fresh setup and it works now. My OneWireCycle tasks runs for around 10seconds. I guess my mistake was that I put the cycle task for the OneWire Task to a too small number. Thx for the support!
