PROFIBUS DP/PA is used to connect field devices such as dis-

tributed I/O stations or operating mechanisms to automation

systems such as SIMATIC S7 or PCs.

PROFIBUS DP/PA is selected when I/O stations on a machine or

in a plant (e.g. the field level) are widely distributed and can

be spatially grouped (>16 inputs/outputs) to form a station

(e.g. ET 200).

In this case the actuators/sensors are connected to field

devices, which are supplied with output data according to the

master/slave principle and send the input data to the controller

or the PC.

Powerful tools such as STEP 7 and COM PROFIBUS are avail-

able to configure and parameterize the I/O stations. With these

tools, tests and start-ups are possible from every connection

using PROFIBUS DP.
