6 EN :2004 (E) Introduction The physical and link layer parameters for baseband communication over twisted pairs has first been described in EN :1997 ("M-Bus") for heat meters. This standard is a compatible and interworking update of a part of EN :1997 and includes also other measured media (water, gas, heat cost allocators), the master side of the communication and newer technical developments. It should be noted that the EN :1997 covers also other communication techniques. It can be used with various application layers especially the application layer of EN
