General introduction to Profibus DP

Introduction

Profibus DP is a serial link field bus for sensors and actuators, which meets the requirements for use in an industrial environment.

This bus uses the master/slave process. The master subscriber manages and co-ordinates access to the bus, it transmits data to and receives data from all the subscribers.

Devices such as input/output modules are also available:

compact Classic TIO slaves:
- classic discrete inputs,
- classic discrete outputs.
DEA203 modular slaves
Momentum modular slaves:
- discrete inputs,
- discrete outputs,
- discrete inputs/outputs,
- analog inputs/outputs.

Input/output modules

Input/output modules are used to link up sensors and actuators for checking or monitoring machines or processes to the Profibus DP system.
