The communication processor 040-1CA00 enables the serial process connection to dif-
ferent destination or source systems. Here the CP is used as peripheral module and
power supplied by the back plane bus.
For the parameterization you may send parameter data to the CP that are differently
assigned depending on the chosen protocol. More about the parameter assignment may
be found in Chapter "Serial communication protocols".

When you send data, which are written by a host system via the back plane bus to the
corresponding output area, to the send buffer, these are sent by the interface.
If the communication processor receives data from its interface, the data are stored in a
circular buffer and transmitted via the back plane bus to the input area of the host system.
Please consider that the size of the I/O area and thus also of the telegram at the back
plane bus depends on the host system. On the following pages the IO area and the com-
munication via the back plane bus are more described.
