what is difference between profibus and field bus?
Answer Posted / niranjan
Fieldbus (or field bus) is the name of a family of industrial computer network protocols used for real-time distributed control, now standardized as IEC 61158.
PROFIBUS (Process Field Bus) is a standard for field bus communication in automation technology.
The Profibus in his Process versión (Profibus PA) is two wire (Twisted pair) for data and power.
fieldbus foundation is only for process (Mainly for instruments), Profibus is for process and automation (instruments, drives, I/O, motor controllers to PLC, PLC to PLC etc.).
