Hi i was having troubles with Modbus RTU, so i did what this page said([8212 with 750-652 modbus trouble](https://www.wago.community/t/8212-with-750-652-modbus-trouble/303)) so i downgraded the Lib (everything worked fine). after installing WagoAppCom i get this error "keine Implentierung für Methode ‘\_GETDWSWVERSION’ aus schnittstelle ‘I\_WAGODMX’ and "keine Implentierung für Methode ‘\_GETDIDMXSTARTADRESS’ aus schnittstelle ‘I\_WAGODMX’. Any idea how to solve this Problem thanks ---

Can you post a screenshot of your library manager placeholder? Something like this: ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/a/a4b053fb5576ac57711e0e88ff036dc0995e6e4c.png) ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/0/05b2c3a1a0293a99f6ed3bd6de0d98036b22842b.png) ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/6/60f771238dc5b88c672d50dd3e42015080fc50b1.png) ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/5/5bb595b4a2add5b98a94fa593406e2ba879422c2.png) I know it’s a long list but will help to find what the problem is. ---

I think I found the problem. After installing the wagoappcom lib, it automatically downgraded the wagotypescom to v1.6.2.0 which caused an error. I noticed it now and changed wagotypescom to v1.6.1.3 and no more errors. I will try to download it and will let you know. 🙂 ---
