Communication<br />
© Siemens AG 2008<br />
CP 441-1, CP 441-2<br />
5<br />
■ Overview<br />
• For powerful, high-speed serial communication via point-topoint<br />
connections<br />
• 2 versions:<br />
- CP 441-1 with 1 variable interface for simple point-to-point<br />
connection<br />
- CP 441-2 with 2 variable interfaces for powerful point-topoint<br />
connection<br />
• Plug-in interface modules for different transmission interfaces:<br />
RS 232C (V.24) , 20 mA (TTY) or RS 422/RS 485 (X.27)<br />
• Implemented protocols: ASCII, 3964 (R), printer drivers;<br />
CP 441-2 additionally has RK 512 and customized protocols<br />
(retrofittable)<br />
• Simple parameterization via a parameterization tool integrated<br />
into STEP 7<br />
