1 INTRODUCTION
The 2400 series of Fast Displays / Alarm Units and the 2500 series of High Performance Controllers with
PROFIBUS-DP Fieldbus interface provide quick integration of typical instrument functions in advanced automation
systems (such as PLC, Supervision Systems, etc.) interconnected via communication networks and standard
EN50170 “PROFIBUS” protocols.
This guide does not describe the “PROFIBUS” Fieldbus: it is assumed that the user is already informed and that he
will refer to the above-mentioned standard or to the official website of the P.N.O. (Profibus Network Organization):
www.profibus.com for any updates.
It is also assumed that the user already has knowledge of the technical characteristics of the 2400/2500, contained
in user manuals enclosed with the products or downloadable from GEFRAN S.P.A.’s website: www.gefran.com.
2 TECHNICAL CHARACTERISTICS
PROFIBUS-DP V0 Slave
Data exchange with PROFIBUS Master 16 I/O process words, configurable, with 35msec minimum refresh
rate.
Automatic identification of communication speed of PROFIBUS network from 9600Baud to 12Mbaud.
Hardware selection of network address via rotary switch (1…99).
Software selection of network address via “SET_SLAVE_ADD” telegram (as alternative to hardware selection).
LEDs for diagnostics and state of PROFIBUS network.
Standard RS485 interface in accordance with EN50170, galvanically isolated from power supply.
Additional technical details on PROFIBUS specifications may be found in the attached file 25000A40.gsd or
24000A40.gsd .
3 INSTALLATION
