PROFINET/Industrial Ethernet
Communication for SIMATIC S7-300
CP 343-1
2
■
Overview
Communications processor for connecting a SIMATIC S7-300/
SINUMERIK 840D powerline to Industrial Ethernet networks,
also as PROFINET IO Controller or IO Device.
The CP supports:
•
PG/OP communication
•
S7 communication
•
Open communication (SEND/RECEIVE)
•
PROFINET communication
■
Benefits
•
High level of plant availability due to support of media
redundancy (MRP)
•
Optimum support of maintenance through
- Web-based diagnostics
- Remote programming via WAN or a telephone network
(ISDN)
- Monitoring by means of IT network management tools
(SNMP)
- Module replacement without programming device thanks to
saving of the configuration data on the CPU
•
Securing the system against unauthorized access by means
of device-related IP address lists
•
The capability of later connecting existing SIMATIC S7
systems to Industrial Ethernet using the CP 343-1 ensures
investment protection
■
Application
The CP 343-1 is used for connecting the SIMATIC S7-300/
SINUMERIK 840D powerline to Industrial Ethernet networks.
With its own processor, it relieves the CPU of communications
tasks and facilitates additional connections.
The CP 343-1 permits communication of the S7-300 with:
• PGs/PCs
•
Master computers
•
HMI devices
•
SIMATIC S7/C7 systems
•
PROFINET IO devices
■
Design
The CP 343-1 has all the advantages of the SIMATIC S7-300
design:
•
Compact design;
on the front, the rugged plastic housing features:
- Two RJ45 sockets for connection to Industrial Ethernet with
automatic sensing of the data transmission rate by means of
Autosensing/Autonegotiation;
the RJ45 sockets are industrially compatible and designed
with additional holding collars for connecting to the
IE FC RJ45 Plug 145/180
- 2-pole plug-in terminal strip for connection of the 24 V DC
external supply voltage
- 8 LEDs for indication of the operating and communication
status (diagnostics for each switch port)
•
Easy installation;
the CP 343-1 is mounted on the S7-300 rail and connected
through the bus connector with the neighboring modules.
No slot rules apply.
•
Fan-free operation;
A back-up battery is not required.
•
Using the IM 360/361, the CP 343-1 can also be operated in
the expansion rack (ER)
•
Modules can be replaced without the need for a programming
device
■
Function
•
PROFINET interface with two RJ45 connectors with
10/100 Mbit/s full/half duplex with autosensing and
autocrossover functionality via integrated 2-port switch
•
Communication services via interface:
- Open communication (TCP/IP, UDP, ISO): Multicast for UDP
- PG/OP communication: inter-network with S7 routing
- S7 communication (client, server, multiplexing)
- PROFINET IO Controller or IO Device
•
Media redundancy (MRP):
- Within an Ethernet network with ring topology, the
CP supports the media redundancy procedure MRP
•
Diagnostics and network management:
- Extensive diagnostic functions for all modules in the rack
- Integration into network management systems through the
support of SNMP V1
•
Security mechanisms:
- Access protection by means of configurable IP access list
•
Configuring of all functions with STEP 7, V5.4 or higher, or
STEP 7 Professional V11 (TIA Portal) or higher
•
Module replacement without programming device thanks to
saving of the configuration data on the CPU
