Consistent and application orientedPROFIBUS is the fieldbus-based automation standard of PROFIBUS & PROFINET International (PI). Via a single bus cable, PROFIBUS links controller or control systems with decentralized field devices (sensors and actuators) on the field level and also enables consistent data exchange with higher ranking communication systems. Consistency of PROFIBUS is enabled by utilizing a single, standardized, application-independent communication protocol (named PROFIBUS DP), which, without any difference, supports fieldbus solutions both in factory and process automation as well as in motion control and safety-related tasks.
PROFIBUS is modularely structured as building block (fig. 1) with the communication protocol as core component. This is combined with application-specific modules for transmission, application (“Applica-tion profiles”) and engineering to form complete PPROFIBUS solutions for specific market segments (industry sectors), as shown in fig. 2.To ensure correct interaction between the numerous devices of an automation solution, the basic de-vice 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 (HART on PROFIBUS).
The "hybrid" factor of PROFIBUS
The value propostion of PROFIBUS
- At the engineering stage it simplifies plant design, eliminates hard wiring and requires less hardware, leading to faster commissioning and lowered costs.
- It also supports better diagnostics, so commissioning is much faster.
- It helps achieve better productivity and higher product quality through the delivery of better and more timely data to operations and management staff.
- It supports advanced asset management strategies that allow plants and equipment to be better managed and maintained.
