1. Introduction
The FX
2N
-32DP-IF Profibus-DP Interface Unit (hereafter called “32DP-IF”) can be used to con-
nect extension blocks/units and special function blocks of FX
2N
/FX
0N
series directly to an exist-
ing Profibus-DP network.
The 32DP-IF provides an intelligent slave function for decentralized control applications. Digital
and analog data from a Profibus-DP master CPU (hereafter called “DP-master”) can be sent
and received to/from any of the supported I/O blocks and special function blocks.
1.1 Features of the 32DP-IF
Using the 32DP-IF extension blocks, units, special function blocks of FX
2N
/FX
0N
series can
exchange data with any DP-master.
• Up to 256 I/O points and/or up to 8 special function blocks can be connected to the 32DP-IF.
However, adjust total control I/O points to 256 or less. See section 1.3.
• The slave address of the 32DP-IF is adjusted by DIP switches. See chapter 5.
• The 32DP-IF can be connected to a Profibus-DP network by a standard 9-pin D-SUB con-
nector and a shielded twisted pair cable complying with EN50170. Optional glassfiber
adapters are supported by the 32DP-IF and are available from other vendors.
See chapter 2.
• An FX-20P-E or personal computer can be used to monitor the devices of the 32DP-IF or to
set parameter for special function blocks connected to the 32DP-IF. For operating instruc-
tions of the FX-20P-E or personal computer, refer to their respective operation manuals and
to section 1.3.1. For device numbers and explanation, refer to Chapter 4. For parameter of
32DP-IF, refer to chapter 6 and appendix B.
