PROFIBUS

PROFIBUS is a smart, field-bus technology. Devices on the system connect to a central line. Once connected, these devices can communicate information in an efficient manner, but can go beyond automation messages. PROFIBUS devices can also participate in self-diagnosis and connection diagnosis.

At the very beginning, the interest group developed PROFIBUS FMS (Fieldbus Message Specification). It was a complex protocol that is no longer used today. After that, they worked to create the PROFIBUS DP (Decentralised Peripherals) protocol and in 1998

PROFIBUS PA (Process Automation) was launched.
Today, when we talk about PROFIBUS, we have the PROFIBUS DP, and PROFIBUS AP. The PROFIBUS DP is one of the 2 variants that is used most frequently. For this reason it is regarded by many experts as the standard PROFIBUS.

Your advantage with PROFIBUS DP:

●Most applied fieldbus in production environments worldwide
●Quick data transfer: at 12 Mbps faster than 1 ms
●Plug-and-play

The PROFIBUS DP network was developed as a quick solution based on an RS485 physical layer and European standard EN-50170. The physical layer does not have to be copper - you can also have wireless or fiber optics.

The PROFIBUS PA protocol was developed as an evolution of HART communication. It is dedicated to field applications, where communication between the measuring instruments and the control system is required.
