The Transfer Software (Only CP 5614)
To operate the CP 5614 with master and slave functionality, you can use the
sample transfer software. The transfer software transfers data between the master
and slave section of the CP 5614.
The transfer software includes an access with which additional input, output or
diagnostic jobs can be executed. Your user program can use this access to add
additional functions to the transfer program. (In the sample program, a counter on
the CP 5614 slave module is incremented.)
The example illustrates how a separate transfer function can access the process
image of the CP 5614 or CP 5613 with a local application.

The Configuration for the Transfer Software (Only CP 5614)
To allow you to specify the separate transfer function, a configuration tool and a
configured transfer file are also shipped as an example.
Using the configuration tool, you can specify how data are copied from master to
slave and vice-versa.
