DP Slave
A DP slave is a peripheral device from which the master reads in input information
and to which it sends output information. There are also devices that provide only
input or only output information.
Slaves are generally inexpensive since passive participation on the bus is simple to
implement.
Figure 1 illustrates the basic structure and the components of a PROFIBUS DP
system controlled by a computer with a PROFIBUS master installed
(CP 5613/CP 5614).
