1. Introduction
The FX3U-32DP PROFIBUS-DP Interface Block (hereinafter called 32DP) enables
users to integrate the MELSEC FX3U PLC into any existing PROFIBUS-DP network
(DP-V0/DP-V1) as a DP-Slave. The 32DP links the FX3U PLC with PROFIBUS-DP
decentralized control tasks. The module connects the PLC system to the DP-Master in
the PROFIBUS-DP network for efficient and easy data exchange.
1) Easy Connectivity to an existing PROFIBUS-DP Network
The 32DP enables the FX3U PLC to fit into an existing PROFIBUS-DP Network as
a DP-Slave, while reducing the time and cost for users to build up a new network
system.
2) Enhanced Data Exchange
The 32DP has enhanced the data exchange functionality in the following
communication formats.
•Cyclic I/O data - a maximum of 144 Bytes
•Acyclic I/O Data - a maximum of 140 Bytes
•User-Diagnostic Messages
•Alarm(Status) Messages
3) Global control
The 32DP supports SYNC / UNSYNC / FREEZE / UNFREEZE global controls.
4) Flexible and Easy Network Setting
The 32DP enables a flexible and smooth integration with components on a new/
existing PROFIBUS-DP Network. The FX3U-32DP PROFIBUS Interface Block is
fully applicable for the user-specific PROFIBUS-DP Network.

5) Various Communication Speed Options
The 32DP supports the communication speeds, 9.6k, 19.2k, 45.45k, 93.75k,
187.5k, 500k, 1.5M, 3M, 6M and 12Mbps to fit into various kinds of networks. To
connect the 32DP to a PROFIBUS-DP Network, use the standard 9-pin D-SUB
connector and shielded twisted-pair PROFIBUS cable complying with EN50170.

2. Installation
2.1 Installation Arrangements
The 32DP is connected to the extension port of an FX3U series PLC or extension
unit/block (including special function unit/block) on the right side.
Since additional extension devices can be added on both the left and right-hand
sides of the PLC, keep an appropriate amount of space on both sides of the PLC
when planning to add extension devices in the future.
For further details on installation arrangements, refer to the following manual.
→ FX3U Series User's Manual - Hardware Edition
2.2 Mounting

→ FX3U Series User's Manual - Hardware Edition
2.2.1 Direct Mounting
The 32DP can be directly mounted with M4 screws.
An interval space of 1 to 2 mm (0.04” to 0.08”) between each unit is necessary.
→ For details on the mounting hole pitch, refer to Section 1.2
2.2.2 DIN Rail Mounting
The 32DP can be mounted on a DIN rail (DIN46227, 35mm width).
1) Fit the upper edge of the DIN rail mounting
groove (right fig. A) onto the DIN rail.
2) Push the product onto the DIN rail.

INSTALLATION
PRECAUTIONS
•Cut off all phases of the power supply externally before installation or wiring
work in order to avoid damage to the product or electric shock.
INSTALLATION
PRECAUTIONS
•Use the product within the generic environment specifications described in the
PLC main unit manual (Hardware Edition).
Never use the product in areas with excessive dust, oily smoke, conductive
dusts, corrosive gas (salt air, Cl2, H2S, SO2or NO2), flammable gas, vibration
or impacts, or exposed to high temperature, condensation, or rain and wind.
If the product is used in such conditions, electric shock, fire, malfunctions,
deterioration or damage may occur.
•Install the product securely using the DIN rail or screws.
•Install the product on a flat surface.
If the mounting surface is rough, undue force will be applied to the PC board,
thereby causing nonconformity.
•When drilling screw holes or wiring, make sure cutting or wiring debris does not
enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
•Be sure to remove the dust proof sheet from the PLC's ventilation port when
installation work is completed.
Failure to do so may cause fire, equipment failures or malfunctions.
•Connect the extension cables and communication cables securely to the
designated connectors.
Contact failures may cause malfunctions.
•Do not touch the conductive parts of the product directly to avoid failure or
malfunctions.

3. Wiring
3.1 Applicable Cable and Connector
The following table shows the applicable cable and connector for a PROFIBUS-
DP network.
3.2 Wiring
To connect the 32DP to a PROFIBUS-DP network, use the PROFIBUS connector
and shielded twisted-pair PROFIBUS cable complying with EN50170.
DESIGN
PRECAUTIONS
•Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to abnormal data written to the
PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main
circuit, high-voltage line, or load line.
Otherwise, noise disturbance and/or surge induction are likely to take
place. As a guideline, lay the control line at least 100mm (3.94") or more
away from the main circuit, high-voltage line, or load line.
2) Ground the shield wire or shield of the shielded cable at one point on the
PLC. However, do not ground them at the same point as the high-voltage
lines.
•Install module so that excessive force will not be applied to the peripheral
device connectors. Failure to do so may result in wire damage/breakage or
PLC failure.
WIRING
PRECAUTIONS
•Cut off all phases of the power supply externally before installation or wiring
work in order to avoid damage to the product or electric shock.
WIRING
PRECAUTIONS
•When drilling screw holes or wiring, make sure cutting or wire debris does not

3.3 Grounding
Ground the cable as stated below.
•Use a grounding resistor of 100Ωor less.
•Ground the cables indepently for best results.
When independent grounding is not used, use "shared grounding" as follows.
→ For details, refer to the FX3U Series User's Manual - Hardware Edition.
•The grounding wire size should be AWG 14 (2 mm2) or larger.
•The grounding point should be as close to the PLC as possible, and all grounding
wire should be as short as possible.
3.4 Bus Terminator
To avoid the signal reflections, connect a self-terminating DP-Connector/Device at
each end of the PROFIBUS-DP Network.
Note
The FX3U-32DP is not sef-terminated.
4. Specifications
DESIGN
PRECAUTIONS
•Make sure to have the following safety circuits outside of the PLC to ensure safe
system operation even during external power supply problems, communication
errors or PLC failure. Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection
circuit, an interlock circuit for opposite movements (such as normal vs. reverse
rotation), and an interlock circuit (to prevent damage to the equipment at the
upper and lower positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error,
during self-diagnosis, all outputs are turned off. Also, when an error that can-
not be detected by the PLC CPU occurs in an input/output control block, output
control may be disabled. External circuits and mechanisms should be designed
to ensure safe machinery operation in such a case.
3) Note that when an error occurs in a relay, triac or transistor output device, the
output could be held either on or off. For output signals that may lead to serious
accidents, external circuits and mechanisms should be designed to ensure
safe machinery operation in such a case
DESIGN
PRECAUTIONS
•Make sure to observe the following precautions in order to prevent any damage to
the machinery or accidents due to abnormal data written to the PLC under the
influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main cir-
cuit, high-voltage line, or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place.
As a guideline, lay the control line at least 100mm (3.94") or more away from
the main circuit, high-voltage line, or load line.
2) Ground the shield wire or shield of the shielded cable at one point on the PLC.
However, do not ground them at the same point as the high-voltage lines.
•Install module so that excessive force will not be applied to the connectors.
Failure to do so may result in wire damage/breakage or PLC failure.
STARTUP AND
MAINTENANCE
PRECAUTIONS
•Do not touch any terminal while the PLC's power is on.
Doing so may cause electric shock or malfunctions.
•Before cleaning or retightening terminals, externally cut off all phases of the power
supply.
Failure to do so may cause electric shock.
•Before modifying or disrupting the program in operation or running the PLC,
carefully read through this manual and the associated manuals and ensure the
safety of the operation.
An operation error may damage the machinery or cause accidents.
