1. About PROFIBUS-DP
1.1

Overview

PROFIBUS-DP TM is a communication protocol used to network industrial devices to eliminate labor intensive and
expensive point to point wiring schemes. Siemens originally developed PROFIBUS DP, but it is now supported by a
multitude of manufacturers and the protocol standard governed by the PROFIBUS Trade Organization (PTO).
The G3 Series PROFIBUS-DP
PROFIBUS Interface Center (PIC) according to the guidelines determined by the PROFIBUS Trade Organization (PTO).
The certification process ensures interoperability for all PROFIBUS-DP devices. This product supports PROFIBUS DP-V0
and DP-V1
PROFIBUS-DP uses a 2-wire (plus shield) network and can have up to 126 nodes. The protocol can transfer a
TM
maximum of 244 bytes of data per node cycle with nine selectable communication (baud) rates of 9.6 Kbps, 19.2
Kbps, 45.45 Kbps, 93.75 Kbps, 187.5 Kbps, 500 Kbps, 1.5 Mbps, 3 Mbps, 6 Mbps and 12 Mbps. Maximum distance is
depended upon baud rate and cable media type. Refer to the section below for details.
