5.7 M-Bus Communication
M-Bus is already embedded in the new Supercal 5 hardware. And up to two further com-
munication modules can still be added in the available slots. This ensures that up to three
M-Bus requests for different applications can be processed and answered simultaneously.
The two additional electrical pulse inputs are automatically integrated into the M-Bus tel-
egram and transmitted. For unambiguous identification of the two electrical pulse inputs,
one identification number and one production num-ber can be parameterized respectively.
The Supercal 5 operates with a variable data structure. An individual primary address and
baud rate can be parameterised for each M-Bus output.
For an M-Bus ”application reset“, the factory settings are set in accordance with the EN 1434
standard.
