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 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 information
• 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
