M-Bus
Field bus modules for capturing consumption data
M-Bus master interface modules
M-Bus (EN 1434-3) is an international standard for remote meter
reading. The M-Bus connection is formed using the PCD2.F27x0 /
PCD3.F27x communication modules in slots 0…1 on the
PCD1.M2* and 0…3 on the PCD2.M5 and PCD3. This makes it
possible to capture all water, heat or energy quantities in an
automation station. The measurement data is subsequently
processed in an FBox library in the Saia PCD® FUPLA.
The interface modules are fitted with a power supply and two
separate M-Bus interfaces. Depending on the design,
the integrated power supply is sufficient for up to 240 M-Bus
standard slave modules whereby it can be distributed
as required across the two ports.
The PCD2.F2700 and PCD3.F270 M-Bus master modules are
compatible with existing FBox libraries based on an RS-232
interface.
The PCD2.F2710…F2730 and PCD3.F271…F273 master modules
require the Engiby M-Bus-Library.
FBoxes for SBC energy meters with M-Bus are supported
by the Engiby library. The usage licence for these FBoxes
is included in the basic package from PG5 2.0 onwards.

Usage
In PCD controllers, M-Bus is connected without a slot for M-Bus
master modules via an external signal converter. RS-232 or
RS-485 interfaces are used depending on the converter.
Driver settings
The respective PCD communication interface is specified
in the Engiby library -Bus driver FBox. Attention should also
be paid to the converter interface parameters such as Baud rate,
time out, etc.
Application example: PCD1.M2120 with M-Bus activation.
