Appendix B: Profibus

Overview

This appendix describes the Gateway's support for Pro-
fibus DP and details the configuration steps necessary
to set up a Graco Gateway with an S7300 PLC,
CPU315-2DP via Profibus. It does not provide a
detailed description of Profibus, but only a brief introduc-
tion, necessary to define the terms that are used
throughout the remainder of this document.

Introduction

Profibus DP stands for "Profibus for Decentralized
Peripherals". Profibus DP is a device level bus that sup-
ports both analog and discrete signals. It has wide-
spread usage for such items as remote I/O systems,
motor control centers, and variable speed drives. Profi-
bus DP communicates at speeds from 9.6 Kbps to 12
Mbps over distances from 100 to 1,200 meters.
