CP 343-1 Lean for Industrial Ethernet / Manual Part B3L

Release 03/2007

C79000-G8976-C198-04

1 Properties / Services

Application

The CP 343−1 Lean communications processor is designed for operation in a

SIMATIC S7-300 programmable logic controller. It allows attachment of the

S7−300 to Industrial Ethernet and supports PROFINET IO.

A 2-port switch with autocrossing, autonegotiation and autosensing was integrated

in the CP for simple integration in a line or for attaching a further Ethernet device.

Services

The CP supports the following communication services:

PROFINET IO device

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

intelligent PROFINET IO device.

S7 communication and PG/OP communication

− PG functions (including routing)

− Operator control and monitoring functions (HMI)

− Server for data exchange on S7 connections configured at one end only

without communication blocks on the S7-300 / C7-300 station

S5 compatible communication with

− SEND/RECEIVE interface over ISO-on-TCP, TCP and UDP connections

− Multicast over UDP connection

The multicast mode is made possible by selecting a suitable IP address

when configuring connections.

− FETCH/WRITE services (server; corresponding to S5 protocol) via

ISO-on-TCP connections and TCP connections;

The addressing mode can be configured for FETCH/WRITE access as the

S7 or S5 addressing mode.

− LOCK/UNLOCK with FETCH/WRITE services;
