Introduction

This FX -32NT-DP Profibus-DP Interface Unit (called "32NT-DP" hereinafter) can be used as
0N
a slave module to connect an FX
(called "PLC" hereinafter) to an existing Profibus-DP network.
The 32NT-DP provides an intelligent slave function for decentralized control applications which
need to exchange data with Profibus-DP master CPUs (called "DP-master" hereinafter).

Features of the 32NT-DP

By using the 32NT-DP the PLC can exchange data with any DP-master.
• The default settings allow to send 16 words and to receive 16 words of data in one
communication cycle. These values can be adjusted between four word and 20 words of
sent and received data.
• The communication between the PLC main unit and the internal buffer memory of 32NT-DP
is handled by FROM/TO instructions.
• The 32NT-DP occupies 8 I/O points on the PLC's expansion bus. The 8 points can be
allocated from either inputs or outputs.
• The 32NT-DP can be connected to a Profibus-DP network by a standard 9-pin D-SUB
connector and a shielded twisted pair cable complying with EN50170. Optional glassfiber
adapters are supported by the 32NT-DP and are available from other vendors.
