Siemens CP343-5 Module

Manufacturer: Siemens

Based on Layer 2 (FDL) of PROFIBUS (IEC 61158/61784), the CP 343-5 offers a simple, optimized interface for process or field communication.

This interface offers integrated, high-performance communication between SIMATIC S5, SIMATIC S7, SIMATIC 505 and PC. SEND/RECEIVE provides not only the SDA service (PLC/PLC connections) but also the SDN service (broadcast, multicast).

STEP 7 V5.1 SP2 or higher is required for configuring the full functional scope of the CP 343-5. In Version V5 or higher of STEP 7, the configuration data of the CP can also optionally be stored on the CPU and is retained even if there is a power failure. A module can therefore be replaced without having to reload the configuration data from a programming device. The CPU transfers the configuration data to the CP during start-up. Attention should therefore be paid to the memory capacity of the S7-CPU.

Configuration and programming of all SIMATIC S7 controllers connected to the network is possible over the network.

The function blocks for using the open communication (SEND/RECEIVE) and FMS can be found in the SIMATIC NET library following installation of STEP 7.

Features Applications Model

Simple integration of the SIMATIC S7 into a multi-vendor automation group by means of PROFIBUS FMS
Extensive reduction of workload for the user of PROFIBUS FMS specification due to simple configuration and independent data conversion of data on the CP
Sub-process-oriented design of an automation solution through the use of several CPs
Integration of the SIMATIC S7-300 into existing systems by means of open communication
Universal application of the CP due to the parallel use of different communication services on one CP

The CP 343-5 communications processor is the module required for SIMATIC S7-300 and SIMATIC C7 for the PROFIBUS bus system.
It offloads communication tasks from the CPU.
S7-300 communication options using communication modules
FMS communication with PROFIBUS FMS stations through PROFIBUS
Communication with programming devices, human machine interface devices
Communication with other SIMATIC S7 systems
Communication with SIMATIC S5 PLCs
The number of CPs that can be operated depends on the performance range of the CPU and the communication services used.
