SIMATIC S7-1500Siemens 6GK7543-1AX10-0XE0 SIMATIC S7-1500 CP 1543-1 Gigabit Ethernet Security Communication Processor
CP 1543-1 Gigabit Ethernet communication processor for SIMATIC S7-1500, IPsec VPN, firewall.
Description
About the CP 1543-1 communications processor CP 1543-1 for connection of SIMATIC S7-1500 to Industrial Ethernet; TCP/IP, ISO, UDP, S7 communication, IP broadcast/ multicast, security (VPN, firewall), diagnostics, SNMPv1/v3, DHCP, FTP client/server, email, IPv4/IPv6, IEEE 802.1X (radius), time synchronization via NTP, 1x RJ45 (10/100/1000 Mbps).

The Siemens 6GK7543-1AX10-0XE0 CP 1543-1 is a communication processor that gives a SIMATIC S7-1500 CPU an additional Industrial Ethernet interface, supporting 10/100/1000 Mbit/s over one RJ45 port with TCP/IP, ISO, UDP, and S7 communication. It includes a stateful-inspection firewall and IPsec VPN with up to 16 connections and AES-256 encryption for secure plant network segmentation.

Selection Notes
Up to 8 units per CPU and 118 simultaneous open-communication or S7 connections make the CP 1543-1 suited to S7-1500 stations that need many parallel Ethernet links, well beyond what the CP 1243-1 supports on an S7-1200. It does not carry DNP3 or IEC 60870-5 telecontrol protocols, so it is the choice for standard plant TCP/IP networking and VPN-secured segmentation rather than substation telecontrol reporting. Sixteen concurrent IPsec VPN connections with AES-256 support isolating an S7-1500 cell on its own encrypted segment while still allowing multiple remote engineering sessions.
Applications
Additional Gigabit Ethernet interface for S7-1500 CPUs, VPN-secured remote access and network segmentation, FTP and email-based IT integration, and static IP routing between plant network segments.
