The gateway takes up the role of a M-Bus Master, i.e. it controls the communication. M-Bus energy meter data can be read either in cycles at certain intervals or on request by the EIB/KNX bus system. Different data formats can be set for each measured value, so that the consumption value can be sent to the EIB/KNX Bus as an integer, a temperature value as a floating point value, etc.. The KNX M-Bus Gateway also offers several diagnosis functions for M-Bus meters, such as automated search and identification of the connected M-Bus slaves. The answering data sent by the meter is presented in detail in clear text, so that the time-consuming procurement of M-Bus telegram description is dispensed with. The diagnosis functions can be used through simple ASCII commands. Parametrization and diagnosis is performed through the integrated USB interfaces in connection with our b+b Terminal software. The gateway hardware consists of a 6TE (= 105mm) wide rail mounting housing with integrated 100V - 240V power unit and connections for M-Bus and EIB/KNX at the same time. The device is maintenance-free without fan or any other wear parts.
