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
PF611 and PF612 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.
The product lineup is as follows:
No. Application Type
1 For model 2000 (master) GPF611**S
2 For model 2000 (slave) GPF612**S
Summary of PROFIBUS module.

Transmission cable RS485 shielded twisted pair cable is used.
Optical fiber can be used partially if optical repeaters are used.
Function Cyclic process data transmission between controller and slave devices.
Conforming standard PF611:EN50170 (DPV0) Profibus Class 1 Master
PF612:EN50170 (DPV0) Profibus-DP Slave
Parameter PF611: Transmission parameters are set from custom configurator.
PF612: Transmission parameters are set from switch on the module or
User program on controller.
The user who combines S2T/S2E and PF611/PF612 and operates must issue various
requests to PF611/PF612 by using the READ/WRITE instruction in the S2T/S2E application
program.
