1 Properties / Services

1.1 Application

The CP 343-1 Advanced communications processor is intended for operation in a

SIMATIC S7-300, C7-300 or SINUMERIK 840D power line automation system. It

allows attachment of the S7-300 to Industrial Ethernet and supports PROFINET.

The CP has the following interfaces:

S PROFINET interface (Ethernet interface ERTEC)

To integrate the CP in a linear bus or ring, to connect a further Ethernet device

or to use PROFINET media redundancy, an IRT-compliant 2-port ERTEC

switch with autocrossing, autonegotiation and autosensing was integrated in the

CP.

S Gigabit interface

The CP also has an Ethernet interface complying with the gigabit standard

IEEE 802.3ab. This is independent of the PROFINET interface and supports

autocrossing, autonegotiation and autosensing. The gigabit interface can, for

example, be used to connect to a PG/PC or to a higher-level company network.

The gigabit interface does not support the following services:

− PROFINET

− Programmed communications connections (FB55 IP_CONFIG).

1.2 Communication services

The CP supports the following communication services:

S PROFINET IO

PROFINET IO allows direct access to IO devices over Industrial Ethernet.

The CP can be used as a PROFINET IO controller and as a PROFINET IO

device at the same time.

− PROFINET IO controller

IO controller mode with alarm block and acyclic data exchange using

read/write data record

− PROFINET IO device

Integration of the SIMATIC S7-300 programmable controller over the CP as

intelligent PROFINET IO device.

PROFINET IO can only be used via the ports of the PROFINET interface.
