1.1 Uses of the CP 340
Introduction
The communication processor allows you to exchange data between programmable
controllers or computers by means of point-to-point communication.
Functionality of the CP 340
The CP 340 communication processor provides the following functionality:
● Transmission rate up to 19.2 Kbaud, half duplex
● Integration of the most important transmission protocols in the module firmware:
– 3964(R) procedure
– ASCII driver
– Printer driver
● Adaptation of transmission protocols by means of parameter assignment with the CP 340
parameter assignment user interface: Point-to-point communication, parameter
assignment
● Integrated serial interface:
Three module variants are available, each having a different interface type that is suitable
for different communication partners (see Module variants table).
