Introduction to PROFIBUS
PROFIBUS (Process Field Bus) is a vendor-independent, open-field
bus standard used in a wide variety of industries, including
manufacturing, process and building automation. Many certified
PROFIBUS products are available, including sensors, motor drives
and starters, PLCs, remote I/O systems, and so on.
There are three types of PROFIBUS products:
✦
Fieldbus Message Specification (FMS)
This version is designed as a general-purpose solution for
communication tasks at the cell level, and can also be used for
extensive and complex communication tasks.
✦
Process Automation (PA)
This version is designed for process automation. It permits
sensors and actuators to be connected on one common bus
line. This version can be used for data communication and
power over the bus using 2-wire technology according to
IEC 1158-2.
✦
Decentralized Periphery (DP)
This version is designed for communication between
automation control systems and distributed I/O at the device
level. This version can be used in place parallel signal
transmission with 24V or 0 to 20 mA.
PROFIBUS-DP
PROFIBUS-DP is a master/slave communication profile, which
allows up to 126 stations on each bus. These stations perform
connection-oriented communication and have a transmission rate
of up to 12 Mbps. The length of the messages between the master
and slave is up to 256 bytes. Information transferred from the
master to the slave is called
Output
, and information transferred
from the slave to the master is called
Input
