Profibus is manufacturer selective (vendor independence) and is used vastly for work Automization as an open type fieldbus. The characteristics of open type are stated in Europe standard EN50170 and EN50204.
Profibus enables communication between different manufacturer's devices without any special interface required. Profibus is very efficient and highly on conditions where careful consideration is required to communicate in complex and high speed environment.
Even when more advanced technology comes in effect, Profibus will be the industrial communication system who will be ready for the future

Advantage of Profibus

- Minimal H/W structure available (I/O, terminal blocks, barriers). Easy and fast installation    reduces cost to construct hardware. - Simple Structure (Every device is constructed as one tool). With simple repair and maintenance,    operation of the system becomes fast and easy. - It provides maximum flexibility to progress of work with power up of main cycle, reducing    incidents of ability decline, dependable data log and trustable digital transmitting technology. - In the area of work atomization, input/output signal connection installation cost must be    minimized and maximum use of Bus's function to reduce many unnecessary input/output signals. - In the area of work atomization, device is located at danger zone and one Twist Pair cable is    used to transfer data to minimize the number of analog I/O card to be used.
