1. Introduction
1.1 Features of the 64DP-M
The FX2N-64DP-M Profibus-DP Master Block (hereafter called “64DP-M”) is a “Class 1” master
for the Profibus-DP network (hereafter called “Profibus-DP”). The FX2N series programmable
controller by connecting 64DP-M can read input data from the Profibus-DP slave (hereafter
called “DP-slave”), and write output data to the DP-slave.
• Controlled maximum slaves:
A 64DP-M can control a maximum of 60 slaves using repeaters on the DP-network.
For system configuration of the Profibus-DP, refer to section 1.3.
• Configuration setting:
Configuration of the 64DP-M can be set easily by MELSEC ProfiMap configuration software
(V3.00 or more). For MELSEC ProfiMap configuration software (hereafter called “ProfiMap),
refer to MELSEC ProfiMap Configuration System for Open Networks Software Manual.
• Communication:
The 64DP-M supports 9.6k, 19.2k, 93.75k, 187.5k, 500k, 1,500k, 3M, 6M and 12Mbps.
The 64DP-M can be connected to a Profibus-DP by a standard 9-pin D-SUB connector and
shielded twisted pair cable complying with EN50170. See chapter 2.
• Global control:
The 64DP-M supports Sync global control, Unsync global control, Freeze global control and
Unfreeze global control.

1.3 System Configuration
1.3.1 Applicable Profibus-DP Network
Note;
• The maximum number of slaves that can be connected to a 64DP-M is 60.
• Number that can be connected for 1 segment
Masters + slaves + repeaters ≤32 units
• Number of units that can be connected to the entire network using repeaters.
Masters + slaves ≤126 units
• Communications can be conducted via a maximum of 3 repeaters from an arbitrary
master or arbitrary slave to an arbitrary master or arbitrary slave. However, the whole
network can contain more than 3 repeaters. (See note above.)

FX2N-64DP-M Profibus-DP Master Block Introduction 1
1-7
Note;
When using a slave with expansion diagnostic information of more than 32 bytes, the
network will be limited. Maximum expansion diagnostic information data length is the
smaller of the value obtained from a slave address by the following equation or 244 bytes.
Maximum expansion diagnostic information data length (bytes)
= [12600 ÷N*1 - 10] or [244]
*1 The value of N is the smaller of the value obtained by the following equation or 300.
N = [(Max. slave address value - Min. slave address value + 1) ×5] or [300]
Note:
It is not possible to communicate normally with the slave when the maximum diagnosis
information data length (Max_Diag_Data_Len) has been decided by the slave’s GSD file is
larger than the value obtained by the above expression.
In this case, please try the following things.
1) Make the slave address consecutive number if possible.
2) Change setting so that this value may become small if the maximum diagnosis
information data length on the slave side can be set.
3) Reduce connected number of the slave.

1.3.2 Applicable Programmable Controller
For setting up a system, the 64DP-M can be connected directly to the FX2N series
programmable controller’s extension port, or to any other extension unit / block’s right side
extension port.
The 64DP-M occupies 8 points of I/O on the FX2N’s expansion bus. The 8 points can be
allocated from either inputs or outputs. The maximum I/O for a FX2N system is 256 I/O.
