PROFIBUS-DP
PROFIBUS-DP
The purpose of the bus system is the fast serial linkage of de-central peripherals (valve batteries) with the
central Master (controller). In addition to the Input/Output data, parameter data, configuration data and
diagnosis data is also transferred.
The PROFIBUS-DP is defined in the DIN 19245 T3 standard.
Many PROFIBUS masters (controllers) need a configuration program with which the network structure is
described. e.g., SIEMENS COM ET200 for the S5 controller. These programs require the unit master file
(GSD file) or, as in the case of the above-mentioned Siemens controller, the Type file. Both files are stored
on diskettes, and contain bus-specific data.
