[Design Instructions]
!
WARNING
Make sure to see this manual for information about each station's operating status when a
communication error occurs in the network. Erroneous outputs and malfunctions may result in
serious accidents.
If a coaxial cable is disconnected, this may destabilize the line, and a data link communication
error may occur in multiple stations. Make sure to create an interlock circuit in the sequence
program so that the system will operate safely even if the above error occurs. Failure to do so
may result in a serous accident due to faulty output or malfunctions.
Provide a safety circuit outside the programmable controller so that the entire system will
operate on the safety side even when an error occurs with the personal computer.
There is a risk of an accident due to faulty output or malfunctioning.
(1) Construct circuits outside the programmable controller, including an emergency stop circuit,
protection circuit, interlock circuit for reciprocal operations such as forward and reverse, and
interlock circuit for positioning high and low limits to prevent damage to the equipment.
(2) If the station in which the board is installed is disconnected from the data link due to a data
link error, the data output from that station and written in other stations will remain the same
as immediately before the error occurred in the data link. This data will be retained until the
data link for that station is reopened (returned to system).
Provide a mechanism to monitor the status of data link and handle errors for each station
that is connected to the data link system.

[Design Instructions]
!
CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause malfunctioning.
[Installation Instructions]
!
CAUTION
Use the board in an environment as described in the general specifications listed in this
operating manual.
If the board is used in an environment outside the ranges described in the general
specifications, it may result in an electric shock, fire, malfunctioning, damage to or deterioration
of the product.
Be sure to shut off all phases of the external power supply used by the system before installing
or removing the board. If all power is not turned off, this will result in failure of the board or
malfunctioning.
Install the board to a personal computer which is compliant with PCI standard or PCI Express
standard (Refer to "Section 2.5 Operating Environment"). Failure to do so may cause a failure or
malfunction.
Securely mount the board to the PCI slot of the mounting device.
If the board is not mounted correctly, this may lead to malfunctioning, failure or cause the board
to fall.
Insert the communication cable securely into the board connector. After it has been inserted,
check to make sure that it is not being lifted up.
A faulty connection can lead to faulty input or output.
When mounting the board, take care not to become injured by the components that are installed
or surrounding materials.

WARNING
Be sure to shut off all phases of the external power supply used by the system before
performing work such as installing the board and wiring.
If all power is not turned off, there is a risk of electric shock or damage to the product.
When turning on the power and operating the module after having installed the board and doing
the wiring, always attach the cover for the device module in which the board is installed.
There is a risk of electric shock if the module cover is not attached.
!
CAUTION
Properly solder the parts of a soldering-type coaxial cable connector. Incomplete soldering may
result in malfunction.
Crimp the parts of a crimping-type coaxial cable connector with proper force at a proper position.
Failure to do so may cause drop of the cable or malfunction.
For the communication cable, specialized skills and tools are required to connect the plug and
cable. The connector plug itself is a custom part.
When purchasing, consult your local Mitsubishi representative.
If the connection is incomplete, this can result in a short, fire or malfunction.
Be sure to fix communication cables connecting to the board by placing them in the duct or
clamping them.
Cables not placed in the duct or without clamping may be hang freely and accidentally pulled,
which may cause damage to the board or cable, or malfunction due to bad cable contacts.
When removing the cable from the board, do not pull the cable.
Pulling the cable that is still connected to the board may cause damage to the board or cable, or
malfunction due to bad cable contacts.
Prevent foreign matter such as chips or wiring debris from getting on the board.
Failure to do so can result in fire, breakdowns or malfunction.
Verify the rated voltage and pin assignment of the product and connect the external power
supply cable properly.
Connecting a power supply with a different voltage rating, imperfect cable crimping or faulty
wiring may cause a fire or failure.
Use a specified tool for crimping of the cable and contacting pin. Imperfect crimping may cause
malfunction.
Verify the pin assignment and fully insert the crimped contacting pin into the connector.
Imperfect insertion may cause failure or malfunction.
Insert the wired external power supply cable into the external power supply cable connector until
a click is heard. Imperfect insertion may cause failure or malfunction.
Keep the external power supply cable away from the main circuit cable, power cables and/or
load cables connected to other than programmable controllers. Ensure a distance of 100mm
(3.94 in.) between them. Failure to do so may result in malfunction due to noise, surge or
induction.
Always ground the personal computer. Failure to do so may cause malfunction.

mode or MELSECNET/H Extended mode. When using the MELSCNET/H board in
the MELSCNET/H network, refer to "Q Corresponding MELSECNET/H Network
System Reference Manual (PLC to PLC network)". Also, when using the board in the
MELSECNET/10 network system, refer to "For QnA/Q4AR Corresponding
MELSECNET/10 network system reference manual".
The MELSECNET/H is a network system which is used to connect multiple sequencer
modules and personal computers, and is equipped with functions and performance
realized in the MELSECNET/10 for general control of a production line.
In the MELSECNET/H, there is a network system which includes an optical loop
system (communication rates: 10 Mbps, 25 Mbps) and a coaxial bus system
(communications rate: 10 Mbps), enabling large volume communications at high
speeds.
Also, in order to improve the performance of the MELSECNET/10 network and achieve
upward compatibility, MELSECNET/H supports the MELSECNET/ H and
MELSECNET/H Extended modes (high performance, high speed mode) and the
MELSECNET/10 Mode (function compatible and performance compatible mode).

(2) By adopting the PCI/PCI ExpressRstandard, complicated switch
settings are no longer required.
The system can be used simply by installing the MELSECNET/H board in the
personal computer, then installing the software.
The channel No., station No. and other settings can be carried out easily in the
MNETH Utility.
(3) Compatibility with the previous MELSECNET/10 board’s operations
is maintained.
(a) Upward compatibility of user programs
Since MELSECNET/H board has the same number of the maximum
mountable board and channel number as the previous MELSECNET/10
board, the exiting user programs can be utilized.
(b) Compatible with the GX Developer, MX Links and MX
Component.

(4) Compatible with multiple CPU systems.
By using station designations of logical station No. on the MNETH utility,
MELSECNET/H board is capable of communicating with a multiple CPU system.
(5) Compatible with redundant CPU systems.
Only by specifying whether the destination is a control or standby station using
the user program, access is simply made without considering the current
operating system state of the redundant CPU system.
(6) Compatible with MELSECNET/H Extended mode
The MELSECNET/H Extended mode is the extended MELECNET/H mode,
which is extended in the maximum number of link points per station. With this
mode, the maximum number of link points per station can be set to 2000 bytes or
more, i.e., up to 35840 bytes.
This mode is suitable for the system that needs many number of link points per
station.

network communication (baton passing) even if a personal computer is powered
off and data link cannot be performed.
Therefore, a normally operating station connected between other stations with
power-off computers will not be disconnected from the data link.
Another advantage is that the link scan time is stabilized since loopback can be
also prevented.
