5.3 ProBus Module (AXM-PRO)
5.3.1 Introduction of PROFIBUS Technology
PROFIBUS (Process Field bus) is an international field bus standard which is
widely used in automation technology of manufactures and ow industry. It is
a widely used, open digital communication system, which is suitable for high-
speed, time-critical, and high reliability communications.
PROFIBUS is one kind of open style field bus standard which is promoted by
SIEMENS Corporation. In 1989, it became the German standard DIN19245, in
1996, it became the European standard EN50170, in 1999 it was accepted as
part of the international standard IEC61158 and in 2001 it became the Chinese
national standard JB/T 10308.3-2001 for field bus of machinery industry
controlling systems.
There are 3 types of PROFIBUS: PROFIBUS-DP (Decentralized Periphery),
PROFIBUS-PA Process Automation) and PROFIBUS-FMS (Field bus Message
Specication). ALL types follow the same protocol.
With optimized, high-speed, low-cost communication links, PROFIBUS-DP
is especially used in automatic controlling systems and equipment level
decentralized I / O communication. It can meet real-time response, stability and
reliability of equipment level and distributed controlling systems.
The PROFIBUS module uses PROFIBUS-DP (V0) protocol.
