1. Introduction
This FX0N-32NT-DP Profibus-DP Interface Unit (called “32NT-DP” hereinafter) can be used as
a slave module to connect an FX0N, FX1N, FX2N or FX2NC*1 series programmable controllers
(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).
*1 When using an FX2NC series PLC, an FX2NC-CNV-IF is required.
1.1 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.

1.4 Applicable PLC
For setting up a system, the 32NT-DP can be connected directly to the PLC’s extension port or
to any other extension unit’s right side extension port.
The 32NT-DP occupies 8 points of I/O on the PLC’s expansion bus. The 8 points can be
allocated from either inputs or outputs. The maximum I/O for the FX0N/FX1N system is 128 I/O.
The maximum I/O for the FX2N/FX2NC system is 256 I/O.
*1 When connecting to an FX2NC series PLC, an FX2NC-CNV-IF is required.

2. Wiring and Mounting
Caution
1) Do not lay signal cable near to high voltage power cable or house them in the same
trunking duct. Effects of noise or surge induction may occur. Keep signal cables a safe
distance of more than 100 mm (3.94") from these power cables.
2) Ground the shield wire or the shield of a shielded cable at one point on the programmable
controller. Do not, however, ground at the same point as high voltage lines.
3) The terminal screws of the 32NT-DP are M3.5 (0.14"), therefore the crimp style terminal
(see drawing) suitable for use with these screws should be fitted to the cable for wiring.
Figure 2.1: Crimp Terminals
4) The terminal tightening torque is 0.5 ~0.8 Nxm. Tighten securely to avoid malfunction.
5) Cut off all phases of power source before installing / removing or performing wiring work on
the master in order to avoid electric shock or damage of product.
6) Replace the provided terminal cover before supplying power and operating the unit after
installation or wiring work, in order to avoid electric shock.

2.1 Mounting
2.1.1 Arrangements
The 32NT-DP connects on the right side of the connected FX0N, FX1N, FX2N or FX2NC*1 series
main unit or extension unit/block (including special function blocks). For further information of
mounting arrangements, refer to the hardware manual of the connected main unit.
*1 When connecting to an FX2NC series PLC, an FX2NC-CNV-IF is required.
2.1.2 Mounting
The mounting method of the 32NT-DP can be DIN rail mounting or direct wall mounting.
1) DIN rail mounting
a) Align the upper side of the DIN rail mounting groove of the 32NT-DP with a DIN rail*1
(c), and push it on the DIN rail(d). See Figure 2.2.
b) When removing the 32NT-DP from the DIN rail, the hook for DIN rail is pulled (e), and
the 32NT-DP is removed (f). See Figure 2.2.
