CP 343-1 Advancedfor Industrial Ethernet / Manual Part B3A

Release 02/2006

C79000−G8976−C202−03

1 Properties / Services

Application

The CP 343−1 communications processor is designed for operation in an S7-300

programmable logic controller. It allows the S7-300 to be attached to Industrial

Ethernet.

Services

The CP 343-1 supports the following communication services:

PROFINET IO Controller

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

PROFINET CBA

Use of a SIMATIC S7-300 for Component based Automation based on the new

PROFINET Standard of the PNO. This standard allows:

− Component technology in automation

− Graphic configuration of communication between intelligent devices instead

of laborious programming

− Vendor−independent, plant−wide engineering

Component based Automation allows access to the variables of PROFINET

components from all standard PC applications with the OPC client interface, for

example, visualization systems. Over the OPC server, objects can be selected

directly from a variable selection list of the selected PROFINET component.

S7 communication and PG/OP communication

− PG functions (including routing)

− Operator control and monitoring functions (HMI)

multiplexing TD/OP connections

− Client and server for data exchange using communication blocks 1 ) on S7

connections configured at both ends

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

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