1. Introduction
The FX2N-32DP-IF(-D) Profibus-DP Interface Unit (called “32DP-IF” hereinafter) can be used
to connect FX2N/FX0N series extension units/blocks and special function units/blocks directly to
an existing 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 (called “DP-master” hereinafter) 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 the FX2N/FX0N series extension units/blocks and special function units/
blocks 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 4.
• The 32DP-IF can be connected to a Profibus-DP network via a standard 9-pin D-SUB connector
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 status of the 32DP-IF and the
data exchanged with the Profibus network. For operating instructions of the FX-20P-E or
personal computer, refer to their respective operation manuals. For device numbers and
explanation, refer to the FX2N-32DP-IF User’s Manual.

1.3 System Configuration
Figure 1.3: System Configuration
*1 The units at each end of the Profibus-DP network must have a terminating resistor. This
will either be in the master, slave unit or in the Profibus connector.
*2 For connecting a monitoring tool, refer to subsection 1.3.1
*3 For connecting units/blocks, refer to subsection 1.3.2.
Caution
The parameter data of the 32DP-IF must be set correctly in the DP-master, if the parameter
data is not correct, the operation of the module may be affected.
For parameter of 32DP-IF, refer to FX2N-32DP-IF User’s Manual.
