The SIMATIC CP 1543-1 communications processor securely connects the new SIMATIC S7-1500 controller to Industrial Ethernet networks. By combining a variety of security features such as an SPI (Stateful Packet Inspection) firewall, VPN and data encryption protocols such as FTPS and SNMPv3, the communications processor protects individual S7-1500 stations or even entire automation cells against unauthorized access.

The CP can also be used for bing the S7-1500 station into an IPv6-based network. All functions are configured by means of STEP 7 Professional V12 (TIA Portal) or higher.

The CP 1543-1 supports the following communications services:

• PG/OP communication
• S7 communication
• Open communication (SEND/RECEIVE, FETCH/WRITE)
• IT communication
  • FTP functions (File Transfer Protocol FTP/FTPS) for file management and access to data blocks in the CPU (client and server function)
  • Sending e-mails via SMTP or ESMTP with "SMTP-Auth" for authentication on an e-mail server (also with IPv6)
• Security functions
  • Stateful Packet Inspection (layers 3 and 4) firewall
  • Secure communication via VPN (IPsec)
  • Secure access to the Web server of the CPU via the HTTPS protocol
  • Secure file transfer using FTPS
  • Secure transfer of the time of day (NTP)
  • SNMPv3 for tap-proof transfer of network analysis inbation
• Integration of the S7-1500 into IPv6-based networks; 
  An IPv6-compliant IP address can be used for the following communication services:
  • FETCH/WRITE access (CP as server)
  • FTP server mode
  • FTP client mode with addressing by program block
  • E-mail transfer with addressing by program block

• Reachability of the SIMATIC S7-1500 station from an IPv6-based infrastructure
• Optimum support of maintenance due to
  • Simple diagnostics via the central Web server
  • Remote programming via LAN
  • Monitoring with IT network management tools (SNMP)
  • Module replacement without a PG
• Securing the system against unauthorized access with
  • Central access protection for any S7 station
  • Secure access to the central Web server
• Network separation for setting up identical machines with the same IP address
• Simple alerting by e-mail and transfer of production data to master computer using FTP
• Protection of investment thanks to simple integration of the SIMATIC S7-1500 system in existing networks with SIMATIC S7-300 / S7-400 / S5 via Industrial Ethernet using the CP 1543-1

The CP 1543-1 is used to connect the SIMATIC S7-1500 to Industrial Ethernet networks. With its own processor, it relieves the CPU of communications tasks and facilitates additional connections.

The CP 1543-1 provides communication options with:

• PGs/PCs,
• master computers
• operator control and monitoring systems,
• other SIMATIC S5/S7 systems.

This can be used to protect the SIMATIC S7-1500 from unauthorized access from an Ethernet network. The CP 1543-1 allows safe remote access via a LAN and allows data transfer between devices or network segments to be protected from data manipulation/espionage.

Protection of the SIMATIC S7-1500 system from unauthorized access from the Industrial Ethernet network

The CP 1543-1 features all the advantages of the SIMATIC S7-1500 design:

• Compact design:
  • One RJ45 jack for connecting to Industrial Ethernet; 
    automatic data rate detection using autosensing, autocrossing and autonegotiation; 
    the connection is made via the IE FC RJ45 Plug 180 with 180° cable outlet or via a standard patch cable
  • The module is supplied with power via the integrated backplane bus
  • Three LEDs for displaying the operational and communications status of the module and one LED under the front cover for the Ethernet interface to display ACTIVITY and LINK.
• Simple installation: 
  The CP 1543-1 is mounted on the rail of the S7-1500 and connected to the adjacent modules by means of the bus connectors.
• The CP 1543-1 can be operated without a fan; no backup battery is required.
• The module can be replaced without the need for a programming device.

• Gigabit interface with RJ45 connector with 10/100/1000 Mbps full/half duplex with autosensing functionality
• Communication services:
  • Open communication (TCP/IP, UDP, ISO): 
    Multicast with UDP
  • PG/OP communication: Inter-network with S7 routing
  • S7 communication (client, server)
  • IT communication: 
    HTTP communication grants access to the web server of the S7-1500 system. With the CP 1543-1, HTTPS communication is also possible.
    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 in the CPU via FTP server.
  • IP address assignment using DHCP with IPv4 or by entering the address directly in the engineering software
    STEP 7 Professional V12 (TIA Portal) or higher
• Diagnostics and network management:
  • Extensive diagnostic functions for all modules in the S7-1500 system
  • Integration in network management systems due to support of SNMP V1/V3
• Security mechanisms:
  • Access protection with firewall for filtering connections on the basis of their IP and MAC addresses
  • Secure communication via VPN (IPsec)
  • Encrypted HTML pages using SSL (HTTPS)
  • Secure file transfer (FTPS)
  • Tap-proof transfer of network analysis inbation to the network management system (SNMPv3)
  • Secure transfer of the time of day (NTP)
  • Certification as per Achilles Level II Standard
