  • Description

The Siemens CP 1543-1 (6GK7543-1AX00-0XE0) is a communications processor that connects a SIMATIC S7-1500 CPU to Industrial Ethernet over a single Gigabit RJ45 port, supporting TCP/IP, ISO, UDP, and S7 communication with IPv4/IPv6 addressing. It adds a stateful-inspection firewall, IPSec VPN, and IEEE 802.1X port authentication, drawing 0.35 A typical from the backplane bus.

Selection Notes

The single Gigabit port plus IEEE 802.1X port authentication and a stateful firewall make this CP suited to S7-1500 stations that sit directly on a plant IT network needing access control, not just PROFINET machine traffic. Choose it over the CM 1542-1 when the station needs VPN, firewall, or 802.1X security rather than baseline PROFINET IO connectivity alone.

Applications

Fits SIMATIC S7-1500 stations that need a secured, routed Ethernet connection into a plant or corporate network - VPN tunneling, IP routing, and 802.1X authentication support IT/OT convergence requirements.
