PROCESS FIELD BUS

Description

Application

PROcess FIeld BUS is a standard for fieldbus communication in automation technology.
PROcess FIeld BUS links controller or control systems with decentralized field devices (sensors and actuators) via a single bus cable on
the field level. It also enables consistent data exchange with higher ranking communication systems. Consistency of PROcess FIeld
BUS is enabled by utilizing a single, standardized, application-independent communication protocol (named PROcess FIeld BUS DP),
which, without any difference, supports fieldbus solutions both in factory and process automation as well as in motion control and
safety-related tasks.
To ensure correct interaction between the numerous devices of an automation solution, the basic device functions and services must
match in regard to communication, functionality and industry sector solutions. This uniformity is achieved by means of “application
profiles” which refer to device families or special industry sector requirements, e.g. process automation (PA Devices), Motion Control
(PROFIdrive) or integration of HART devices.
PROcess FIeld BUS DP is in the central position and carries communication data between a controller and field devices, preferably in
Factory Automation (FA). PROcess FIeld BUS PA string is connected through a coupler or linking device to enable typical process
automation (PA) applications, e.g. in a hazardous environments. The controller is connected to PROcess FIeld NET as system bus and
interface to MES and ERP levels. PA segments can also be connected directly to PROcess FIeld NET using proxy technology.
