- For fast, high-performance serial data exchange via point-to-point connection
- 2 versions:
- CP 441-1 with 1 variable interface for easy point-to-point coupling.
- CP 441-2 with 2 variable interfaces for high-performance point-to-point connection.
- Plug-in interface modules for different physical transmission properties:
RS 232C (V.24), 20 mA (TTY) or RS 422/RS 485 (X.27) - Implemented protocols: ASCII, 3964 (R), printer driver;
for CP 441-2 additional RK 512 and Modbus RTU (reloadable) - Simple parameter assignment using tool integrated in STEP 7
