Ok, the problem is that the trend/trace system can't read function block instance data. The variables has to be stored directly under the program calling the FBs. Thus, FB variables to be trended/traced must be connected to variables declared in the program. Seems like a bug to me!

UC20-M4000 Redundancy – Application is not automatically synchronized and redundancy breaks after online change

Hello, I am currently testing redundancy using two UC20-M4000 controllers with CODESYS Control SL. The basic redundancy functionality (Active/Passive switching and failover) works, but I am experiencing problems when updating the application. Environment Controller: Weidmüller UC20-M4000 OS: u-OS Runtime: CODESYS Control SL 4.12.1.0-1 Redundancy link: dedicated Ethernet connection between the two controllers Time synchronization: NTP configured, time difference between controllers is about 1–2 seconds Current behavior Application synchronization When I download a modified application to PLC1 (Active controller), the application is not automatically copied to PLC2 (Passive controller). However, when I perform a path swap, the application download to PLC2 starts automatically. My expectation was that the Passive controller would automatically receive the updated application after downloading to the Active controller. Online change When performing an online change, redundancy is lost and the controllers switch to Standalone mode. Typical log messages include: RedundancySynchronize called Redundancy failover itself works correctly. The application boot project exists on both controllers (Application.app and Application.crc). Network interfaces are up and correctly configured. Question Is this behavior expected when updating the application in a redundant UC20-M4000 setup? Should the Passive PLC automatically receive the updated application, or is manual synchronization required? Any advice or recommended configuration for stable redundancy during online change and application download would be greatly appreciated. Thank you.

Were you able to figure out if it is possible to change the Application/Product URI of your server? I am having the same problem.

From Codesys support: The format of the URN is always the same. It's always urn:<vendor>:<product>:OPCUA:Server. What I think you can influence the vendor and product (DeviceName) through settings in the runtime cfg file:</product></vendor> [SysTarget] VendorNameUnicode="T\00E\00S\00T\00" DeviceNameUnicode="t\00e\00s\00t\00" Note that these are 16-bit strings, thus the ASCII padded with nulls
