Product Identification & Function
This is the SIMATIC CP 243-1 communications processor, order code 6GK7243-1EX01-0XE0, a double-width S7-200 module that connects SIMATIC S7-22X CPUs to Industrial Ethernet at 10/100 Mbit/s via a single RJ45 port. It serves as an active spare part for existing installations, providing FTP client/server, HTTP server, email client, and web-based diagnostics without requiring additional software on the CPU.
Integration Dimensions & Environment
The module measures 62 mm deep, 71.2 mm wide, and 80 mm high, fitting the double-width S7-200 form factor on a DIN rail. Rated IP20, it operates at 0 to 55 °C when horizontally mounted on busbars, or 0 to 45 °C for vertical installation. Power is drawn from the backplane bus (5 V DC, 0.06 A typical) and can optionally use an external 24 V DC supply via a 3-pole terminal block; total module power loss is 1.5 W.
