The task of the bus system is to provide a high-speed serial connection between the decentralised periphery

and the central master (controller). In addition to the input and output data, parameter, configuration and dia-

gnositc data are also transmitted.

The PROFIBUS

-DP is defined in accordance with DIN 19245 Part . Many PROFIBUS

masters (control-

lers) require a configuration program with which the network structure is described. These programs require

the device data base file (DDB file). It contains bus-specific data.
