Profibus DP Bus Flexible Cable Application

PROFIBUS represents one of, if not the number one, the largest installed bases of Fieldbus systems in the world. Using shielded twisted pair constructions, the two main application-specific profiles are PROFIBUS DP, which optimized for discrete factory automation, and PROFIBUS PA, which optimized for process automation.

PROFIBUS (Process Field Bus) is a standard for Fieldbus communication in automation technology and was first promoted in 1989 by BMBF(German department of education and research) and then used by Siemens. It should not be confused with the PROFINET standard for industrial Ethernet. PROFIBUS is openly published as part of IEC 61158.

Profibus DP cables are designed for field networks requiring fast, cyclic data exchange between controllers and field devices. This cable is usually referred to as Siemens Profibus. This Profibus modification optimized with respect to velocity and low installation cost. Profibus DP used as a replacement for conventional parallel data transmission with 24 V or 0 – 20 mA.
