SIMATIC S7-1500 Communication SIPLUS NET CP 1543-1 6AG1543-1AX00-2XE0

Overview

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 linking 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 user 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)
  • Access (read and write modes) to csv files stored on the memory card of the CPU via FTP(S)
  • Sending emails via SMTP or ESMTP with “SMTP-Auth” for authentication on an email server (also with IPv6)
  • Static IP routing with up to 1 Mbps via IPv4 to other CM 1543-1 / CM 1542-1 units in an S7-1500 system, e.g., for web server accesses without real-time capability. Securing a cell by activating the security function in the CP 1543-1 automatically deactivates IP routing.
• 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 information
  • Encrypted email communication via SMTPS (Port 587)
  • Open communication over TCP/IP
• 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
  • Email transfer with addressing by program block

Benefits

• 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

Application

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.
