info

Before you start assigning, make sure the offline created M-bus device and the matching discovered devices either uses the same primary address or the address property field of the offline created M-bus device is empty. Note that, if you copy an assigned M-bus device into the custom library, it will keep its primary address. Therefore, either adjust or delete the address for next assigning.
