SIMATIC S7-400
Communication
CP 441-1, CP 441-2
■ Overview
• For powerful, high-speed serial communication via point-topoint
connections
• 2 versions:
- CP 441-1 with 1 variable interface for simple point-to-point
connection
- CP 441-2 with 2 variable interfaces for powerful point-topoint
connection
• Plug-in interface modules for different transmission interfaces:
RS 232C (V.24) , 20 mA (TTY) or RS 422/RS 485 (X.27)
• Implemented protocols: ASCII, 3964 (R), printer drivers;
CP 441-2 additionally has RK 512 and customized protocols
(retrofittable)
• Simple parameterization via a parameterization tool integrated
into STEP 7
5
