Hello, I have a question regarding the “WagoAppPLCInfos\_FR.FbSystemInfo” library in CoDeSys V3.5 SP21 PATCH 3. I am able to add this library and retrieve the PLC information. However, for CoDeSys V3.5 SP19 PATCH 7, even after adding this library, I encounter library errors. Is there a solution or another library compatible with SP19 PATCH 7 to retrieve this information (firmware version, PLC model, K-bus error code)? Thank you in advance for your help. ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/7/7eb53f4de31a73701f5a0296c82e8ea679e9e063.png) Best regards, ---
