PROFIBUS is an open standard communication protocol which has been designed 
and developed for use in general industrial applications. The standard is defined in 
EN50170 (volume 2) and has been developed, agreed and adopted by many 
manufacturers worldwide. 

PROFIBUS control is now available for a wide variety of products, from many 
different companies manufacturing drives, actuators, valves, as well as 
Programmable Logic Controllers (PLCs) and other system controllers. PROFIBUS 
operates over a variety of hardware interconnections such as fiber optics and 
RS485. 

There are three versions of PROFIBUS: FMS, DP and PA and all these versions 
will work together. The most commonly used version is the DP version, intended 
for general industrial applications. This is the version supported by Siemens Drives. 

In order to connect to a PROFIBUS system, a PROFIBUS module is required. This 
module mounts on the side of the drive and uses a TTL serial port to communicate 
with the drive. 

The drive may be controlled and monitored via the main PROFIBUS system. 

A PROFIBUS system offers the following advantages: 

 

Open, clearly defined system.  

 

Many different products from many different manufacturers.  

 

Well proven in many industrial applications.  

 

Reduced wiring; easy set up re-programming, monitor and control.  

 

Ease of commissioning with the SIMATIC S7 PLC System at a later date.  

 

Flexibility to expand and modify the automatic system at a later date.  

 

Remote diagnostics reduce the downtime in the event of a problem.  

 

Very fast; up to 12 Mbaud.  

 

Up to 125 slaves on one DP system.  

 

Single or Multi-master operation.  

 

One to one or broadcast communications.  

 

Support and development software available.
