Overview
- The connection of SIMATIC S7-300/SINUMERIK 840D powerline to Industrial Ethernet
- Multi-protocol operation with TCP and UDP transport protocol
- Adjustable keep-alive function
- Two separate interfaces (integrated network separation):
- Gigabit interface with one RJ45 port with 10/100/1000 Mbps, full/half-duplex with auto-sensing capability
- PROFINET interface with two RJ45 ports with 10/100 Mbps full/half-duplex with auto-sensing and autocrossover functionality via integrated 2-port switch
- Communications services via both interfaces:
- Open communication (TCP/IP and UDP): Multicast with UDP, including routing between both interfaces
- PG/OP communication:
Cross-network by means of S7 routing - S7 communication (client, server, multiplexing) including routing between both interfaces
- IT communication:
HTTP communication supports access to process data via own web pages;
email client function, sending of emails directly from user program;
FTP communication supports program-controlled FTP client communication;
access to data blocks through FTP server
- Communications services via PROFINET interfaces:
- PROFINET IO controller and IO device with real-time properties (RT and IRT)1)
- PROFINET CBA
- IP address assignment via DHCP, simple PC tool or via program block (e.g. for HMI)
- Configuration with STEP 7
- Media redundancy (MRP);
within an Ethernet network with ring topology, the CP supports the media redundancy procedure MRP (V2.2 or higher). - Access protection by means of configurable IP access list
- Module replacement without programming device;
all information is stored on the C-PLUG (also file system for IT functions) - Extensive diagnostic functions for all modules in the rack
- IT communication
- Web function
- Email function
- FTP
- Integration into network management systems through the support of SNMP V1 MIB-II
1) possible combinations in parallel operation:
– IO controller with IRT and IO device with RT
– IO controller with RT and IO device with IRT
Benefits
- Cost advantage resulting from connection to two separate Ethernet segments with network separation
- High level of plant availability due to support of media redundancy (MRP)
- Optimum maintenance support thanks 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 removable data storage medium
- Securing the system networks1) against unauthorized access by means of
- Central access protection for any devices within an automation cell, e.g. by means of strong authentication of network stations by means of a stateful packet inspection firewall
- 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 commonly used 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

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.
Design
The CP 343-1 Advanced offers all the advantages of SIMATIC S7-300 system design:
- Compact design:
- Three RJ45 jacks for connecting to Industrial Ethernet via two independent interfaces;
one of which is a security jack for externally safeguarding the network cell;
automatic data rate detection by means of the autosensing, autonegotiation and autocross functions;
the connection is made via the IE FC RJ45 Plug 180 with 180° cable outlet or via a standard patch cable - 2-pin plug-in terminal strip for connection of the 24 V DC external supply voltage
- Diagnostics LEDs for indicating the operational and communication status
- Three RJ45 jacks for connecting to Industrial Ethernet via two independent interfaces;
- Simple installation;
the CP 343-1 Advanced is mounted on the S7-300 mounting rail and connected to adjacent modules by means of the bus connector. There are no slot rules. - The CP 343-1 Advanced can be operated without a fan;
no backup battery is required. - In combination with IM 360/361, the CP 343-1 Advanced can also be used in an expansion rack (ER).
- The module can be replaced without the need for a programming device
- C-PLUG (configuration plug) is included in the scope of delivery as a removable storage medium (cannot be operated without C-PLUG)
Function
- Two separate interfaces (integrated network separation):
- Gigabit interface with an RJ45 connector with 10/100/1000 Mbps full/half duplex with autosensing functionality
- 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 both interfaces:
- Open communication (TCP/IP, UDP, ISO):
Multicast with UDP, including routing between both interfaces - PG/OP communication: Inter-network with S7 routing
- S7 communication (client, server, multiplexing) including routing between both interfaces
- IT communication:
HTTP communication permits access to process data via user’s own Web pages. HTTPS communication is also possible with the CP 343-1 Advanced1).
The e-mail client function allows e-mails to be sent directly from the user program.
FTP communication allows program-controlled FTP client communication.
Access to data blocks via FTP server.
