优势

Expansion of the process I/O to SIMATIC S7-300 with severalPROFIBUSDP interfaces

Flexible use of the process I/O by means of dynamic activationof DPslaves

Sub-process-oriented design of an automation solution throughtheuse of several CPs

Optimization of applications and a host of possible uses thankstoactive transmission of data with S7 communication

Extensive operator control and monitoring thanks tomultiplexfunction with OP communication

Suitable for closed-loop control tasks due to SYNC/FREEZE

The CP 342-5 communications processor is the communicationsmoduleof the SIMATIC S7-300 for the PROFIBUS DP bus system.

The CP 342-5 relieves the CPU from communication tasks.

SIMATIC S7-300 communication options by means ofcommunicationsmodules:

As DPmaster or slave for PROFIBUSDPV0according toIEC61158/EN50170

Communication with programming devices and HMI devices

Communication with other SIMATIC S7 systems

Communication with SIMATICS5 programmable controllers

The number of CPs that can be used depends on the performancerangeof the CPU and on the communications services used.

The CP 342-5 offers all the advantages of SIMATIC S7-300systemdesign:

Compact design;
single standard width of the SM modules of the SIMATIC S7-300

9-pin Sub-D socket for connection to PROFIBUS

4-pin terminal block for connecting the external supply voltageof24 V DC

Simple assembly;
The CP 342-5 is mounted on the S7-300 DIN rail and connectedtoadjacent modules by means of the bus connectors. Slots 4 to 11insubracks 0to 3 (coupled through the IM360/361) can beused for theCP342-5

In combination with IM 360/361, the CP 342-5 can also be used inanexpansion rack (ER)

User-friendly wiring;
Sub-D socket and the terminal block are easily accessible.

The CP 324-5 can be operated without a fan;
a back-up battery or a memory module is not required

The CP342-5 provides access to different communicationservices ofthe PROFIBUS bus system:

PROFIBUSDP (according to IEC61158/61784, master orslave)

PG/OP communication

PROFIBUS DP master

The CP 342-5 operates as a DP-V0 Master accordingtoIEC61158/EN61784 Volume 2 and processes the datatransfercompletely independently. It supports the services of theMasterClasses 1 and 2.

The data areas of the distributed I/Os are transferredconsistentlybetween CP and CPU. This applies to the use of the CPas DP Masterand as DP Slave. As DP Master, it permits connectionsto:

SIMATIC S7-300, such as CP342-5 as DP slave

DP slaves of the distributed I/O system ET200 (integrateas DP-V0slave)

PCs, e.g. with CP 5512, CP 5621, CP 5614 A3 andSOFTNET-PBDP

The CP342-5 also offers the SYNC/FREEZE and sharedinput/outputfunctions, as well as the activation/deactivation ofDP slaves.

PROFIBUSDPslave

The CP342-5 as a DP-V0 slave permits the SIMATIC S7-300 toexchangedata with other PROFIBUS DP masters. which allows a hybridsetupbetween SIMATIC S5/S7, PCs, ET200 and other fielddevices toPROFIBUSDP. Function calls are required for the DPcommunication.These (DP-SEND/DP-RECV) must be integrated in theSTEP7 userprogram.

PG/OP communication allows all S7 stations connected to thenetworkto be remotely programmed.

S7 routing
With the aid of S7 routing it is possible to use programmingdevicecommunication across networks.
Via the CP342-5 as many as 16 TD/OPs can be merged into oneS7-300station. This requires only one connection resource in theS7-CPU(multiplex channel). The multiplex channel supports theacyclic HMIservices.

S7 communication

S7 communication is used for the coupling:

between SIMATIC S7 automation systems

to HMI devices (OPs).

to PCs, e.g. CP 5711 with SOFTNET-PB S7, CP 5623 etc.

Communication with PG and OP takes place withoutfurtherconfiguration. In addition, the central controller can alsobeprogrammed and configured on a distributed basis viatheCP342-5.

The client functionality is provided by means ofloadablecommunication blocks.

Based on Layer 2 (FDL) of PROFIBUS, the CP 342-5 offers asimple,optimized interface for process or field communication.

This interface offers integrated, high-performancecommunicationbetween SIMATIC S5, SIMATICS7, SIMATIC505 andPC.SEND/RECEIVE provides not only the SDA service(PLC/PLCconnections) but also the SDN service (broadcast,multicast).

The communication partners are the automation systems:

SIMATIC S7
with CP342-5, CP343-5, CP443-5 Extended andBasic
