NOTE: The following only applies to models: FS-QS-1A50, FS-QS-1A51, FS-QS-1B50, FS-QS-1B51,
FS-QS-1C50 and FS-QS-1C51.
The M-Bus driver allows the FieldServer to transfer data to and from devices using M-Bus protocol. The
Fieldbus connection is included with the FieldServer. The M-Bus QuickServer Gateway is configurable to
act as both a Master and a Slave M-Bus device.
The M-Bus Connector consist of a + and – terminal. Most M-Bus Devices are not polarity sensitive, although
the polarity of the M-Bus Connector is indicated on the device diagram, should it be a requirement. The M-
Bus devices to communicate with the FieldServer must be configured according to the manufacturer's
instructions (for example primary address and readout data).
