Siemens 6GK7243-1BX30-0XE0 Profibus DP Interface

Siemens 6GK7243-1BX30-0XE0 CP 1243-1 Communications Processor extends SIMATIC S7-1200 by adding an Ethernet interface and enabling secure remote communication to control centers via TeleControl Basic, DNP3, and IEC 60870 protocols. The module provides a single Industrial Ethernet interface (RJ45) and is powered from the backplane bus with a 5 V supply, drawing about 0.25 A (typical) and dissipating roughly 1.25 W. Security features include a built-in firewall and VPN to protect remote connections, supporting SCADA and telemetry applications that require encrypted access and controlled remote maintenance. Designed for seamless S7-1200 integration, the CP1243-1 carries Siemens’ standard support and is covered by a 2-year warranty.
