Applications Of The Cp 440 - Siemens SIMATIC CP 440 Manual

Product Description
1.1

Applications of the CP 440

The CP 440 communication processor enables you to exchange data between
programmable controllers or computers by means of a point-to-point connection.
The CP 440 is designed to transfer short, fast frames.
The following are typically connected to it:
Scanners, barcode readers
Sensors
Weighing scales
Functionality of the CP 440
The CP 440 communication processor provides the following functionality:
An integrated MPI (Multipoint) X27 (RS422/485) interface
A maximum transmission length of 200 bytes
A transmission rate of up to 115.2 kbps, full-duplex
Integration of the most important transmission protocols in the module firmware
– ASCII driver
– 3964(R) procedure
Customization of the transmission protocols by means of parameter assignment
with the CP 440: Point-to-Point Communication, Parameter Assignment
parameterization interface.
Applications of the CP 440
The CP 440 communication processor allows point-to-point communication with
SIMATIC modules and with non-Siemens products. The SIMATIC modules that
can be connected are listed in Appendix C.
