Introduction 1
1-1
1. Introduction
The FX2N-32DP-IF(-D) Profibus-DP Interface Unit (hereafter called “32DP-IF”) can be used to
connect FX2N/FX0N series extension blocks/units and special function blocks/units 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 (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 FX2N/FX0N series extension blocks/units or special function blocks/units 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 6.
• 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 3.
• 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 and to section 1.3.1. For
device numbers and explanation, refer to Chapter 5. For parameter of 32DP-IF.

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 a detailed overview of
the parameter of 32DP-IF, refer to chapter 7.
1.3.1 Connected Programming Tools
An FX-20P-E or personal computer can be used to monitor the 32DP-IF and the data
exchanged with the Profibus-DP. For operating instructions of the FX-20P-E or personal
computer, refer to their respective operation manuals. For device numbers and explanation,
refer to chapter 5.
Connecting cable is same as FX2N MPU.
Caution
For monitoring the 32DP-IF with a personal computer the PLC setting must be adjusted as
for the FX series PLC type.

1.3.2 Connected Extension Units/Blocks
The tables below shows extension units/blocks and their data lengths when connected to a
32DP-IF. Data is exchanged between the 32DP-IF and DP-master during every cycle. The
maximum amount of data that can be exchanged with the 32DP-IF is total 200 bytes of input
data + output data, and user parameter is maximum 193 bytes. Please check the specification
of the DP-master, it may limit the total amount of exchanged data.
For the exchange data length, refer to table 1.9.

1.3.3 Configuration Rules
1) Total I/O points on the system ≤256 points
The 256 I/O maximum point includes all the categories below in addition to the I/O of the
extension module.
a) I/O points for the extension I/O units/blocks (including additional occupied points)
Refer to Table 1.7 for I/O point allocation for each extension unit/block.
b) I/O points for the special function units/blocks
A 32DP-IF can connect a Maximum of 8 special function units/blocks.
Refer to Table 1.7 for I/O point allocation for each special function unit/block.
c) I/O points for FX2N-32ASI-M’s active slaves
2) Supply 24V DC (total internal and service power supply) and 5V DC to the extension I/O
blocks and special function units/blocks from the 32DP-IF or extension I/O unit.
Use the same configuration rules for the FX2N-48ER-UA1/UL, FX2N-48ER-DS and FX2N-
48ET-DSS as applies to the FX2N-48ER-ES/UL.
If 24V DC and/or 5V DC is insufficient for the extension I/O units/blocks and special function
units/blocks in this rule, the hardware configuration should include a powered extension I/O
unit.
For power consumption, refer to Table 1.5 ~ 1.14 and Figure 1.4 ~ 1.7. However, information
concerning Table 1.11 ~ 1.14 is same as Figure 1.4 ~1.7.
a) Check the loading on the 5V DC bus supply. Consumption values for special function
blocks can be found in Table 1.7. See the Table 1.4 for maximum available current.
b) Check the loading on the internal 24V DC supply for FX0N-3A, FX2N-2AD and FX2N-2DA.
Consumption values for these blocks can be found in Table 1.7. See the Table 1.5 for
maximum available current.
Use the same configuration limits for the FX2N-48ER-UA1/UL, FX2N-48ER-DS and FX2N-
48ET-DSS as applies to the FX2N-48ER-ES/UL.
c) Check the loading on the 24V DC service supply and internal 24V DC supply. Check the
number of expansion I/O in Figure 1.4 ~ 1.7 or Table 1.11 ~ 1.14. Find the residual
current.
When using the FX2N-2AD, FX2N-2DA or FX0N-3A, 24V DC service power supply must
retain the current consumption for those blocks' internal 24V DC supply. (Refer to Table
1.7)
Use the same configuration rules for the FX2N-48ER-UA1/UL, FX2N-48ER-DS and FX2N-
48ET-DSS as applies to the FX2N-48ER-ES/UL.

*1 When using the FX0N-3A, FX2N-2AD or FX2N-2DA, total internal 24V DC supply for those
blocks is limited to the values listed in Table 1.5 below.
*2 The 24V DC power supply capacity for the FX2N-32DP-IF-D is used for only internal 24V
DC power source because it does not have a 24V DC service power supply.
*3 Use the same configuration rules for the FX2N-48ER-UA1/UL, FX2N-48ER-DS and FX2N-
48ET-DSS as applies to the FX2N-48ER-ES/UL.
3) Total exchange data length ≤ 200 bytes
(or DP master’s maximum exchange data length if ≤ 200 bytes)
The following (a, b) exchange data must be a total of 200 bytes (or DP master’s maximum
exchange data length if ≤ 200 bytes) or less.
For DP-master’s maximum exchange data length, please see manual of DP-master.
a) Total exchange data for extension I/O units/blocks.
For exchange data for each extension I/O unit/block, refer to Table 1.9.
b) Total exchange data for special function units/blocks.
For exchange data for each special function unit/block, refer to Table 1.9.
