System connections for SIMATIC

Communication modules for SIMATIC allow further uses through additional functions using CPs such as security, integration in the customer's IT infrastructure, and network separation. In addition, they allow flexible expansion with additional communication interfaces for PROFIBUS or PROFINET depending on needs.

CPs with standard functions

• CP 243-1 for SIMATIC S7-200, CP 343-1 Lean and CP 343-1 for SIMATIC S7-300, CP 443-1 for SIMATIC S7-400, CM 1542-1 for SIMATIC S7-1500.
• Designed for use in harsh industrial environments
• Shipbuilding certification for use on ships and offshore units
• Additional integrated 2-port switch for CP 343-1 Lean, CP 343-1, CP 443-1 and CM 1542-1, e.g. for setting up Industrial Ethernet segments in linear and ring structures
• Increased availability through support for Media Redundancy Protocol (MRP)
• Can be used via RJ45 interface for the industrial-standard SIMATIC NET FastConnect cabling system
• High-speed data transfer even with large volumes of data (10/100 Mbit/s)

CPs with function expansions

  • Operation in SIMATIC H system for redundant S7 communication
  • Operation in fail-safe applications (PROFIsafe) together with SIMATIC S7-400 CPU 416F
• The CP 443-1 RNA (Redundant Network Access ¹⁾) for interfacing to an S7-400 or S7-400H via the PRP redundancy protocol (Parallel Redundancy Protocol to IEC 62439-3) on parallel, separate networks, in which high reliability is required.
  The CP supports:
  • PG/OP communication
  • S7 communication
  • Open communication (SEND/RECEIVE)
• CP 1243-1 for SIMATIC S7-1200
  • With security functionality (firewall and VPN)
  • With IT functionality
  • For remote diagnostics and remote maintenance
  • With TeleControl Basic functionality - rapid and flexible data communication via remote networks with caching of data values including automatic time stamping
• CP 1543-1 for SIMATIC S7-1500
  • With security functionality (firewall and VPN)
  • With IT functionality
  • For integrating the S7-1500 into IPv6 based networks.
    For the following communications services, an IP address according to IPv6 can be used:
    - FETCH/WRITE access (CP is server)
    - FTP server mode and FTP client mode with addressing via program block
    - E-mail transfer with addressing via program block

1) At Siemens Industry, RNA stands for hardware and software for implementing redundancy solutions. RNA contains the PRP V1 protocol in accordance with the IEC 62439-3 standard (Parallel Redundancy Protocol) as well as the HSR protocol in accordance with IEC 62439-3 (High-availability Seamless Redundancy Protocol).

Setup of Industrial Ethernet segments with SIMATIC modules with integrated switch

To set up Industrial Ethernet segments in a line or ring topology, all PROFINET communication modules offer integrated 100 Mbit/s switches with at least 2 RJ45 ports. The integration of the switch in the terminal devices allows the setup of very flexible networks and saves cabling costs.
