The CP 1543SP-1 communications processor connects the ET 200SP Distributed Controller with Industrial Ethernet networks. By combining a variety of security features such as an SPI (Stateful Packet Inspection) firewall, VPN and data encryption protocols (e.g. SNMPv3), the communications processor protects individual ET 200SP Distributed Controllers or even entire automation cells against unauthorized access.

The module can also be used for integrating the ET 200SP Distributed Controller into an IPv6-based network. All functions can be configured with STEP 7 Professional, V14 and higher (TIA Portal).

The CP 1543SP-1 supports the following communication services:

• PG/OP communication
• S7 communication
• Open communication (Open User Communication)
• 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 (layer 3 and 4 firewall)
  • Secure communication via VPN (IPsec)
  • Secure access to the web server of the CPU via the HTTPS protocol
  • Secure transfer of the time of day (NTP)
  • SNMPv3 for tap-proof transfer of network analysis information
• Integration of the ET 200SP Distributed Controller into IPv6-based networks

• Prevention of data loss, production disruptions or machine damage by protecting against unauthorized access to the SIMATIC ET200SP Distributed Controller and lower-level networks.
• Network separation for setting up identical machines with the same IP addresses
• Optimum support of maintenance due to
  • Simple diagnostics via the central Web server
  • 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
• Simple alerting by e-mail
• Protection of investment thanks to easy integration of the SIMATIC ET 200sp Distributed Controller in existing networks with SIMATIC S7-300 / S7-400 via Industrial Ethernet using the CP 1543SP-1
• Accessibility of the ET 200 SP Distributed Controller from an IPv6-based infrastructure

The CP 1543SP-1 is used for connecting the ET 200 SP Distributed Controller to Industrial Ethernet networks. With its own processor, it relieves the CPU of communication tasks.

The CP 1543SP-1 offers possible communication with:

• PGs/PCs
• Master computers
• Operator control and monitoring systems
• SIMATIC S7 systems

It can be used to protect the ET 200 SP Distributed Controller automation system from unauthorized access from an Ethernet network. The CP 1543SP-1 allows secure remote access via a LAN and enables the data transfer between devices or network segments to be protected from data manipulation/espionage.

Connection to higher-level network and network separation of automation cells

The CP 1543SP-1 has all the advantages of the ET 200SP design:

• Compact, space-saving design:
  • Module powered via separate power supply
  • Three LEDs for displaying the operating state and communication state of the module as well as LEDs on the bus adapter.
  • Simultaneously operable with BA Send module and CM DP module.
• Simple installation: 
  The CP 1543SP-1 is mounted on the ET 200SP DIN rail and is connected to the adjacent modules via the backplane bus.
  • The bus adapter (not included in scope of delivery) makes various connection methods possible;
  • For standard environmental conditions, BA 2xRJ45 for connection via RJ45 connector
  • For mechanical loading during operation and/or increased EMC requirements 
    BA 2xFC, BA 2xLC, BA LC/RJ45, BA LC/FC, BA 2xSCRJ, BA SCRJ/RJ45, BA SCRJ/FC
  • The CP 1543SP-1 can be operated without a fan; no backup battery is required.
  • The module can be replaced without the need for a programming device.
• The CP can be equipped with an equipment labeling plate.
• Optional labeling using light gray or yellow labeling strips. There is a choice of two materials:
  • Film and roll with 500 strips, for thermal transfer roll printer
  • Paper (280 g/m2), DIN A4 sheets with 100 strips each, for laser printer

Scope of delivery:
CP 1543SP-1, 24 V DC connector (bus adapter must be ordered separately)
