!
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.

MELSECNET/H Board
(Q80BD-J71LP21-25)
This is a manual you read when using the MELSCNET/H board in the MELSECNET/H
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).

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.
(7) Drivers are provided for compatibility with each OS.
Each type of driver is provided, so it is easy to build a system that is compatible
with the user environment.
For details on the compatible operating system, refer to Section 2.5.
(8) User programming functions are provided.
Through MicrosoftRVisual BasicRand MicrosoftRVisual C++Rcompatible
functions, it is possible to carry out remote control of a programmable controller
CPU or read and write to devices, and user programs can be created easily.

1 OVERVIEW

computer
(9) External power supply allows continuous network communication
even during power-off of personal computer. (Function of the
Q80BD-J71LP21S-25)
Since power is supplied externally, the Q80BD-J71LP21S-25 can continue
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.

2) By a link refresh, the B0 information is stored in the refresh data
storage area (LB) of the MELSECNET/H board.
3) The B0 information in the refresh data storage area (LB) is stored in
the link data storage area (LB).
4) By a link scan, the B0 information in the link data storage area (LB) is
stored in the link data storage area (LB) of the network module on the
receiving station.
5) The B0 information in the link data storage area (LB) is stored in the
refresh data storage area (LB).
6) By a link refresh, the B0 information is stored in the device memory
storage area (B) of the CPU module.
7) B0 on the receiving station turns on.
1: The link refresh interval is set on the "Driver" screen in the MNETH Utility.
2: Set by the GX Developer’s "Station Inherent Parameters." (If not set, they are stored in the common
parameters state.)
3: If the MELSECNET/H board is a control station, it is set in the "Common Parameter Setting" screen in
the MNETH Utility. If the network module is a control station, it is set in the GX Developer’s "Common
Parameters."

5.1.2 Installation in a control panel
The installation in the control board ensures safety as well as effective shielding of
personal computer-emitted electromagnetic noise.
(1) Control panel
(a) Use a conductive control panel.
(b) Mask off the area used for grounding when securing the top or bottom plate
to the control panel using bolts.
(c) To ensure electrical contact between the inner plate and the control panel,
mask off the bolt installation areas of an inner plate so that conductivity can
be ensured in the largest possible area.
(d) Ground the control panel with a thick ground cable so that low impedance
can be ensured even at high frequencies.
(e) Keep the diameter of the holes on the control panel to 10cm or less. If the
diameter is larger than 10cm, electromagnetic wave may be emitted. In
addition, because electromagnetic wave leaks through a clearance
between the control panel and its door, reduce the clearance as much as
possible. Use of EMI gaskets (sealing the clearance) can suppress
undesired radiated emissions.
The tests by Mitsubishi were conducted using a control panel having the
damping characteristics of 37dB (maximum) and 30dB (average)
(measured at 3m distance, 30 to 300MHz).
(2) Wiring power and ground cables
The power supply cable and ground cable for a personal computer should be laid
out as follows:
(a) Provide a ground point to the control panel near the power supply module.
Ground the LG and FG terminals of the power supply module to the ground
point with the thickest and shortest ground cable possible (30cm or shorter).
(b) Twist the ground cable leading to the ground point with the power supply
cable. By twisting it with the ground cable, the noise leaking from the power
supply cable may be grounded at a higher rate. However, twisting the
power supply cable with the ground cable may not be necessary if a noise
filter is installed on the power supply cable.

5.1.3 Cables
Use a shielded cable for the cable extended out of the control panel.
If a shielded cable is not used or not grounded correctly, the noise immunity will not
meet the required value.
(1) Grounding a shield cable
(a) Ground the shield of the shield cable as near the exit as possible from the
control panel.
If the ground point is not near the outlet, the cables after the ground point
will cause electromagnetic induction, and will generate a higher harmonic
noise.
(b) Ground the exposed shield to large area on the control panel. A clamp fitting
can be used as shown below.
In this case, mask off the inner wall surface of the control panel, where
comes in contact with the fitting.
Screw
MELSEC
Clamp fitting
Paint mask

POINT
Grounding with a vinyl-coated wire soldered onto the shield of the shielded cable as
shown below is not recommended.
Doing so will raise the high-frequency impedance, resulting in loss of the shielding
effect.

Crimp terminal
(2) Treatment of the coaxial cable ground
(a) Always use a double-shielded coaxial cable (MITSUBISHI CABLE : 5C-2V-
CCY) for the coaxial cables Q80BD-J71BR11. Ground the double-shielded
coaxial cable by connecting its outer shield to the ground.
Refer to (1) for the grounding of the shield.

5.1.4 Ferrite core
Ferrite core is effective for reducing radiated noise in the 30MHz to 100MHz frequency
band.
It is recommended to install a ferrite core if a shield cable extended out of the control
panel does not provide sufficient shielding effects.
Install a ferrite core to the cable in the position immediately before the cable is
extended out of the control panel. If the installation position is not appropriate, the
ferrite core will not produce any effect.
(Ferrite core used for the tests conducted by Mitsubishi: TDK ZCAT3035-1330)
5.1.5 Noise filter (power supply line filter)
Noise filter is effective for reducing conducted noise in the 10MHz or less frequency.
(Use of a noise filter can suppress noise.)
The installation precautions are described below.
(1) Do not bundle the
cables on the input side and output side of the noise filter.
If bundled, the output side noise will be induced into the filtered cable on the input
side.

This section explain precautions for connection of the coaxial cable and Q80BDJ71BR11 in the coaxial bus system.
(1) Precautions in connecting
(a) Restrictions on the cable length between the stations
1) When connecting between the network modules, the cable lengths
indicated in the table below should be used according to the number of
stations connected.
A communication error may occur if a cable length other than the
lengths indicated in the table is used.
0 to 1 m (3.28 ft.) (cable less than 1m (3.28 in.) in length cannot be used.)
1 (3.28 ft.) to 5 m (16.4 ft.)
5 (16.4 ft.) to 13 m (42.65 ft.)
13 (42.65 ft.) to 17 m (55.78 ft.)

25 (175.63 ft.) to 300 m (984.3 ft.)
300 (984.3 ft.) to 500 m (1640.5 ft.)
2) If there is a possibility of adding more stations to expand the existing
system, the cables should be installed by considering restriction 1)
mentioned above in advance.
3) When using a repeater module (models A6BR10 or A6BR10-DC), use
the station-to-station cable length for "10 to 33" stations, regardless of
the number of stations connected or the number of repeater modules.
(b) Cable installation precautions
1) Install the coaxial cables at least 100 mm (3.94 in.) away from other
power cables and control cables.
2) Consider to use double-shielded coaxial cables in locations where
there is excessive noise.

7.3 Common Parameters
The common parameters are used to set the cyclic transmission ranges of LB, LW, LX
and LY that can be sent by each station in a single network. The common parameter
settings are required only for the control station. The data of the common parameters
are sent to the normal stations when the network starts up.
7.3.1 Send range for each station (LB/LW settings)
Assign the send ranges of the link devices (LB/LW) for each station in 16 point units for
LB (start
0 to end
F) and in one point unit for LW.
The following example shows send range for each station (LB/LW settings) when each
of 512 points is assigned to station numbers 1 to 8.
Perform the setting of each station's transmission range (LB/LW settings) in the
"Common parameter setting" screen in the MNETH utility.
