M-Bus
field bus module for capturing consumption data
M-Bus master interface module
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 enables all
volumes of water, heat or energy to be captured in an automa-
tion 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 inte-
grated 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.F2710…F2730 and PCD3.F271…F273 master mod-
ules require the Engiby M-Bus library.
FBoxes for SBC energy meters with M-Bus are supported by
the Engiby library.

M-Bus via serial interface
In PCD controllers, M-Bus is connected with no 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 M-Bus driver FBox in the Engiby library.
Note the converter interface parameters such as baud rate,
timeout, etc.
Secondary addressing
Secondary addressing is supported from Library Version 2.7.200
or higher for SBC energy meters and generic FBoxes. Primary
addressing must be used for the product-specific FBoxes.
Application example: PCD1.M2120 with M-Bus activation.
