Chapter 1 Module Overview
1.1 General
PROFIBUS is an international standard network developed by Siemens that is certified
by German industrial Standards (DIN19245), European Standards (EN50170), and
International Standards (IEC-61158). At the actual application level, there are more than
1,100 companies participating in the user group with approximately 300 vendors
providing approximately 2,000 different products in the European and North American
market. PROFIBUS is classified into DP, FMS, and PA which respectively applies to high-
speed remote I/O, inter-controller message communication, and instrumentation
applications. The PF311 and PF312 supports PROFIBUS-DP, which is the most popular
among these.
The PROFIBUS module enhances connectability by providing PROFIBUS connection to
integrated controllers in addition to conventional device net module.
