PROFINET/Industrial Ethernet
Communication for SIMATIC S7-300
CP 343-1 Advanced
2
■
Overview
Communications processor for connecting the SIMATIC S7-300/
SINUMERIK 840D powerline to Industrial Ethernet networks,
also as PROFINET IO controller and IO device.
The CP supports:
•
PG/OP communication
•
S7 communication
•
Open communication (SEND/RECEIVE)
•
PROFINET communication
•
IT communication
•
Security functionality, firewall and VPN
In addition, the CP 343-1 Advanced provides e-mail functions
and allows users to create their own Web pages - ideal support
for maintenance and quality assurance. The Internet functions
such as FTP even allow connection to the most diverse
PC-based systems. This CP is therefore the bridge between
the field level and the management level for the S7-300.
The CP 343-1 Advanced connects seamlessly to the security
structures of the office and IT world.
■
Benefits
•
Cost advantage resulting from connection to two separate
Ethernet segments with network separation
•
High level of plant availability due to support of media redun-
dancy (MRP)
•
Optimum support of maintenance due to
- Web-based diagnostics
- Remote programming via WAN or telephone network
- Monitoring with IT network management tools (SNMP)
- Module replacement without programming device using the
C-PLUG swap medium
•
Securing the system
1)
against unauthorized access
by means of
- Central access protection for any devices within an
automation cell, e.g. by reliable authentication of the network
nodes
- Secure remote access via the Internet by means of data
encryption (VPN) and data integrity checking
- Traceability by means of data logging on the basis of
standard IT mechanisms (Syslog)
•
The ability to connect existing SIMATIC S7 systems to
Industrial Ethernet at a later point in time using the CP 343-1
Advanced ensures investment protection
1)
Security functions, firewall and VPN only with -1GX31 variant

Application
The CP 343-1 Advanced is used to connect the SIMATIC S7-300
to Industrial Ethernet networks. With its own processor, it relieves
the CPU of communications tasks and allows additional
connections.
The CP
343-1 Advanced provides the following communications
options:
• PGs/PCs
•
Master computers
•
Operator control and monitoring systems
•
SIMATIC S5/S7/C7 systems
•
PROFINET IO devices/IO controllers
•
PROFINET CBA components
With this, all the devices of an Ethernet network can be protected
from unauthorized access. The CP 343-1 Advanced allows
secure remote access over the Internet and allows data transfer
between devices or network segments to be protected from data
manipulation/espionage.
PROFINET CBA components and security functionalities can
only be used alternatively.
