1.3 PROFIBUS DP

PROFIBUS DP is a fieldbus network that provides easy interconnection between control
devices (PLC, PC, sensor, actuator, etc.).
PROFIBUS DP was co-developed by Siemens, Bosch, and ABB as an open
communication standard to connect various field devices (sensor, actuator, robot controller,
etc.). Because of the open communication standard, PROFIBUS DP can easily construct
multi-vendor system with various devices developed around the world.

Compared with a parallel wiring, PROFIBUS DP employing dedicated 2-wire cable
substantially reduces the number of necessary wires, wiring time and cost.
Detachable communication connector provides you a simple wiring between devices
(stations) and an easy network separation or reconstruction.
PROFIBUS DP communication speed can be set up to 12Mbps. This is faster than
DeviceNet, another communication standard supported by the fieldbus I/O.
Due to an open communication standard, various devices from many manufacturers are
available. Standardized communication connectors allow you to reconstruct your network
easily.
Maintenance parts stored on site (factory, etc.) can be reduced because different
manufacturers' devices can be used in case of a breakdown. Similar products are available
around the world due to a global standard PROFIBUS DP.
