Operating instructions for KME flow meter for compressed air and gases
Secondary addressing:
In addition to primary addressing, the KME flow meter provides the option of secondary address -
ing. The secondary address uses the fields of identification number, manufacturer, version and
medium. The M-Bus Standard http://www.m-bus.com/files/MBDOC48.PDF describes the exact
sequence of the secondary addressing.
Data transmission:
Factory settings Adjustable values
Baud rate 2400 600, 1200, 2400, 4800, 9600
Data bits 8 8
Parity EVEN None, odd, even
Stop bits 1 1 or 2
Slave address 240 0...254
For several devices on the bus the max. recommended baud rate is 9600.
4.2.2 Modbus rtU (projected)
KME flow meter can be operated in a Modbus RTU network with max. 32 devices. Writing 0 into
the corresponding register will reset the MIN/MAX values and the consumption meter.
For Modbus protocol settings see Application Note Modbus AN0103.
