I thought I knew what I am doing, but something is missing what?

1. From Device-Communication Settings select from drop down menu "Device"
2. Select entry "Change Runtime Security Policy"
3. Check the "Allow anonymous login"
4. Select "Symbol Configuration" in your application
5. In settings check "Support for OPC UA features"
6. Check some of the values you want in your set
7. Press the build button in the "Symbol Configuration"
8. Press the button "Configure Symbol Rights"
9. Make sure that Anonymous_OPCUAServer has access right to your "default set"
10. From Device-Communication Settings select "Access Rights" in RemoteConnections-OPCUAServer Anonymous_OPCUAServer should be given modify and view rights I suppose.
    I can connect with UaExpert but I cannot see my Application or browse my values. What is missing?

When you have a deep object structure where not all values are not exposed to OPC UA, the top object will not have a V check mark but be filled fully out. In that case CODESYS do not always registrate changes to inner object. Solution set a V in the checkbox of the top object, build, download. Now you can browse, but all values in the top object will be selected, then you can deselect the ones you don't want, build, download and it works
