Protocol overview and
support by rmware for
the different CPUs
Purpose Supported by
PCD1.M1xx PCD2.M110 PCD2.M120 PCD2.M150 PCD2.M170 PCD2.M480
PGU with pin 6 (DSR) of
the PGU connector set
to logical “1” (P800, Full
Protocol)
Programming, debugging; replaced
on newer releases by an equivalent
function with S-Bus Parity mode

S-Bus PGU on the PGU
port, with pin 6 (DSR) of
the PGU connector set to
logical “0” (Data, Parity or
Break mode, Full Protocol)
Programming, debugging,
visualization. Also allows access via
gateway to stations within a different
S-Bus network

Serial S-Bus on any serial

mode)
Exchange of data with other
controllers or with RIOs; previously
called just S-Bus

Character mode (MC1 to

Transmission of characters or text
over serial ports; basis for creating
own protocols in the user program


1) Requires the use of the PCD8.K111 programming cable
2) Requires an appropriate conguration in hardware settings
3) Requires an assignment of the port in the user program (SASI). For new applications, Data mode should always be
selected. Exceptions: on PCD7.D7xx terminals, Parity mode is used
4) Break mode is not supported; Parity mode cannot be used on port 1
5) Obsolete; for new applications, use Serial S-Bus Data mode instead
6) MC5 Mode (RS-485 with immediate release of data line after transmission of the last character) requires the
following minimum rmware versions:
PCD1.M1x0: V080
PCD2.M110 / M120: V090
PCD2.M150: V0C0
PCD2.M170: V010
A.3.2 Protocolsimplementedintheuserprogram
Based on Character mode (and a very good knowledge of LI programming), any
desired protocols can be implemented.
Our system partners have already done this for a large number of protocols, enabling
our controllers to communicate with components from a variety of manufacturers, e.g.
via Modbus, M-Bus etc.
