ADA65-5283d
The SIMOVERT MASTER-
DRIVES Vector Control units
have several serial interfaces
for communicating with, e.g.
higher-level PLC systems,
PCs etc. The interfaces can
be classified as follows:
� Basic version:
Two serial interfaces,
COM1 and COM2, as standard
on the basic unit
� Options:
Communication and interface
boards for different
transmission protocols or
bus systems.
Interfaces on the basic unit
Compact and chassis units
� Serial interface 1 (COM1) is
located on the PMU operator
control and parameterizing
unit. It is a 9-pole SUB D
socket (X300) as an RS485
or RS232 interface (see
page 2/7).
� Serial interface 2 (COM2) is
located on the X101 control
terminal strip of the CUVC
board as an RS485 interface
(see page 2/8).
Compact PLUS units
COM1 and COM2 are connected
to the X103 SUB-D
socket. COM2 is also connected
to the X100 connector.
COM1 is designed as an
RS232 interface and COM2
is designed as an RS485 interface.
Both serial interfaces of the
basic unit work with the
USSr protocol, are bus-capable
(with up to 31 nodes) and
enable maximum data transfer
rates of 38.4 kbit/s.
USS protocol
The USS protocol is a
Siemens-specific transmission
protocol for drive technology
and is implemented
as a standard protocol on all
interfaces of the basic units.
The USS protocol enables
bus operation of up to a
maximum of 32 nodes on
the basis of the RS485 transmission
system.
