Full form-Process field bus. PROFIBUS is not one communication system, but a variety of protocols built on the same field-bus technology bundle. Users can combine varieties of PROFIBUS protocols with their own software and other requirements, resulting in a unique application profile. With many profiles available, PROFIBUS can suit specific needs. One thing remains the same, though. Through thorough testing, PROFIBUS devices meet a high standard of quality befitting a high quality network. It 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 most basic level, PROFIBUS benefits from superior design of its OSI layers and basic topology. it uses the bus topology. In this topology, a central line, or bus, is wired throughout the system. Devices are attached to this central bus. One bus eliminates the need for a full-length line going from the central controller to each individual device. In the past, each PROFIBUS device had to connect directly to the central bus. Technological advancements, however, have made it possible for a new “two-wire” system. In this topology, the PROFIBUS central bus can connect to a ProfiNet Ethernet system. In this way, multiple PROFIBUS busses can connect to each other. The second type of PROFIBUS is more universal. Called PROFIBUS DP, for Decentralized Periphery, this new protocol is much simpler and faster. PROFIBUS DP is used in the overwhelming majority of PROFIBUS application profiles in use today. Application profiles allow users to combine their requirements for a specific solution, and they will be discussed in more detail shortly. PROFIBUS DP has, itself, three separate versions. Each version, from DP-V0 to DP-V1 and DP-V2, provides newer, more complicated features. PROFIBUS PA is a protocol designed for Process Automation. In actuality, PROFIBUS PA is a type of PROFIBUS DP Application profile. PROFIBUS PA standardizes the process of transmitting measured data. It does hold a very important unique characteristic, though. PROFIBUS PA was designed specifically for use in hazardous environments. In most environments, PROFIBUS PA operates over RS485 twisted pair media. This media, along with the PA application profile supports power over the bus. In explosive environments, though, that power can lead to sparks that induce explosions. To handle this, PROFIBUS PA can be used with Manchester Bus Powered technology (MBP). Hope this helps.

muffi Posts: 95 Rating: (10)	Hi As I a little research about profibus ; this is a communication protocol that industrial hardware use for exchange data in industrial network. The base of profibus is that it's at first send some data to slave for known the slave devise .after slave inform itself to master ;master Send some data to slave for set the parameter in slave for example name of slave, and next master start exchange data whit slave(read input; write out put diagnostic data and …) Profibus is this rule for exchange data between master (plc for example) and slave (ET200 for example) I put some pdf file for you that I thing can help you If you need more data tell to put them for you Attachment Profibus.pdf (455 Downloads)
