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 e-mails via SMTP or ESMTP with "SMTP-Auth" for authentication on an e-mail server (also with IPv6)
Static IP routing with up to 1 Mbps via IPv4 to other CM 1543-1 or CM 1542-1 units in a SIMATIC S7-1500 station, e.g., for web server accesses (no real-time capability) to subordinated devices 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 e-mail 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:
