Motionnet Local Input Board MNET-D340 YA7082-0/1
1. Preface
Thank you for purchasing our input board, a local board from our Motionnet ultra-high speed serial
communication system series.
□
The MNET-D340 board you have purchased is a 32-point parallel input board which contains a G9002
IO device for ultra-high speed serial communication.
This board is controlled by a center board, which is equipped with a G9001A Motionnet Center device.
Use the center board together with this board.
□
Motionnet is an ultra-high-speed serial communication system created by NPM (Nippon Pulse Motor).
Using our four specially developed devices (G9001A, G9002, G9003, and G9004) as core chips, this
serial communication system is a complete system for reducing wiring while affording remote operation
by emulating a CPU and handling CPU message communications, as well as controlling input and
output, at transfer speeds of 20 Mbps.
Device
G9001A: Center device
This is a central controller that manages local devices. This device has 256 bytes of RAM for I/O
control, and 512 bytes for data communication. This device can be operated from a remote CPU
just like accessing a memory. It can be connected to a maximum of 64 local devices (G9002,
G9003, and G9004).
G9002: IO device
This is a local I/O control device that can control 32 separate I/O signals.
G9003: PCL device
This is a local device containing a pulse control LSI that has been developed and polished by NMP
for use in motion control over many years. It also has a serial communication function. It can control
single-axis pulse input type stepper motors and servomotors.
G9004: CPU emulation device
This is the most sophisticated local device in the Motionnet series, and it can remotely control other
LSIs that need a connection to a CPU (for example a PCL6045B made by NPM). By connecting a
CPU to its local side, it can also communicate messages between CPUs.
RemoteI/O
If a Motionnet line is only used for input and output control, it can send and receive signals for 2048
points on 64 local devices in 0.97 msec (using a 20 Mbps data transfer speed). (If a smaller number of
devices are connected, the data transfer time will be proportionally shorter.)
RemoteMotion
If a Motionnet line is only used to control motors, it can control up to 64 axes. With this type of control,
individual devices can control pulse-input type stepper motors and servomotors. They can execute
continuous operations at constant speed, linear acceleration/deceleration, and S-curve
acceleration/deceleration, as well as carry out preset positioning operations, and zero return operations.

R

Motionnet Local Input Board MNET-D340 YA7082-0/1
A system combining these two motor types is also possible.
Although it depends on the number of devices connected and the data transfer speed selected, the
cable length can be extended up to 100 m using an ordinary CAT5 LAN cable.
The serial communication uses a receive-respond type protocol. This protocol adds a CRC
number to the communication frame to detect errors, thus offering higher reliability. You can use it
without worrying about the accuracy of the communication.
□
This instruction manual describes the specifications and methods for using the MNET-D340. We want
you to read this manual thoroughly and get full use of the functions offered by this board.
This manual does not describe the detailed functions of the G9001A and G9002 LSIs for
ultra-high-speed serial communication systems.
For the details about the functions and registers of these LSIs, please read NPM's "User's Manual for
the G9001A/G9002, LSIs for the Motionnet ultra-high speed serial communication system."

Motionnet Local Input Board MNET-D340 YA7082-0/1
2. Features
Data transfer speed
20 Mbps, maximum
Data transfer cycle
A maximum of 0.97ms, when using 64 I/O boards.
(At a transfer speed of 20 Mbps, and using our recommended 50 m cable.)
Number of devices that can be connected
Maximum 64 I/O boards/line, with 2048 points connected.
Connection method
Multi-drop connections using LAN cables.
Serial communication types
Three types of communication are available.
1) System communication
By polling the Motionnet line, the number of local devices that are connected, the device numbers,
device types, and I/O port allocation status can all be checked.
2) Cyclic communication
The system starts communication with the local device that has the lowest device number. When
the communication cycle reaches the device with the highest device number, the system starts over
again, communicating with the device that has the lowest device number. The process of
communicating with all active devices, from the lowest to the highest device, is one cycle. The
system always repeats this communication cycle, automatically.
Input and output are controlled using cyclic communication.
3) Data communication
This type of communication is used to read and write data between a PCL device and a CPU
emulation device.
Data is written into a FIFO buffer in the center device, and then a send command is issued. These
communications are sent and received automatically, during the interrupt driven cyclic
communications.
Communication error detection
Errors can be detected by adding CRC numbers to the serial communication frames.
Input
- Number of input points: 32 points
- Isolation method: Photocouplers
Common input specifications
8 input points are configured as one group. This group is independent from all other groups. Each
group has one common line. Using jumpers, they can be connected to the power supply that is also
supplying power to the power connector.

3. Handling Precautions
Inputting power
Do not connect or disconnect connectors while this board or peripheral circuits are supplied with
power.
Static electricity
This board uses a CMOS device. Therefore this board must be stored in a package in which it was
shipped until you actually use it, in order to prevent damage from static electricity.
Switch settings
This board is equipped with switches to set device number and details for serial communications.
Be sure to shut off the power supply to the board before changing these switches.
Connections to electrically noisy devices
Interference from excessively noisy devices or from power surges on the power and I/O circuits may
cause the board to malfunction. To connect to a device, which may generate electrical noise, we
recommend taking countermeasures, such as attaching a protective circuit to the input/output circuits.
However, it is best not to share the same power supply with noise generating sources.
Heat generation of circuit elements
Input resistors, output transistor arrays, and other elements may generate heat and thus become
hot, depending on the operating conditions. If this happens, take steps such as using forced
cooling.
4. Warranty Period and Coverage
Warranty period
12 months after being shipped from our factory.
Warranty coverage
During the warranty period, we will repair without charge any problems on the board that occurred
while it was being used appropriately, and where the cause of the problem is due to us.
However, the following cases will be not be covered by the warranty, even if the warranty period has
not expired.
- Problems caused by inappropriate handling or use.
- Problems caused by using parts not made or approved by us.
- Problems caused by modifications made to the board that were not authorized by NPM.
- Problems caused by disasters, accidents, or fires.
We warranty only the product as delivered, and we do not accept responsibility for any loss caused by
a fault in our product. We will repair the board when the user sends it to our plant.

8-2. Serial communication (RS485+, RS485-)
Function
These are the Motionnet serial signals.
Interface
1) Serial communication signals are isolated by using a pulse transformer. They are input and output
by a line transceiver (SN65HVD1176D or equivalent) that meets the RS-485 specifications.
The board inputs/outputs the forward phase of the line transceiver through the RS485 plus side and
the reverse phase through the RS485 minus side terminals.
2) Termination resistance
In order to prevent reflection of the serial communication line signals, termination resistors must be
present at the start and end points of the line.
The serial communication setting witch (SW2) is used to enable/disable the termination resistance.
By turning on this switch, the termination resistance of 120 ohm is enabled on the board. Be sure to
turn this switch on if the board is the last one on the serial communication line.

These are terminals used to supply control power to the board. The 5 V and 3.3 V internal control
voltages are created from these lines using an isolated DC/DC converter.
The power terminals can be connected to the common lines of the input/output signal circuits using
jumpers.
The frame ground (FG) is connected to the serial communication connector case. Be sure to ground
the FG to the ground.

9-2-3. Setting the watchdog timer (TM)
Set the time for the watchdog timer that is used to monitor the communication status. When the interval
between data communications from a center board, on which the G9001 is mounted, exceeds the time
set here, the watchdog timer will time out.
Possible causes of a time out are an abnormality on the serial communication line, and that the center
board communication has stopped.
This interval time varies with the data transfer time selected.

9-2-4. Break frame request (BK)
This function is used to add to the number of local boards, or to restore a specific local board that has
previously been excluded from cyclic communication due to a communication error.
The center board on which the G9001 is mounted sends regular break frame sending request data
(approximately every 250 ms at 20 Mbps) to local devices. A local device, which has sent a break frame
request, will respond this communication from the center device.
When the center board confirms the response, the corresponding status bit “BRKF” will be changed to
“1” and an interrupt will occur.
With this sequence, the center board realizes that a local board has been added to the communication
line.

10. Status Display
10-1. Communication status display LED (RUN)
When the G9002 in the local board receives serial communications data successfully, the MSEL LED
will be lit green.
If there are a lot of local boards connected to the serial communication line, the LED may be somewhat
dimmed. This LED is green.
10-2. Communication status display LED (ERR)
When an error occurs, such as a CRC error in the serial communication data, the G9002 MRER LED is
lit red.
10-3. Power indicator LED (3.3 V)
Shows that 3.3 VDC is available internally. Lights yellow.
10-4. Input/Output signal display LED
When any of the input/output signals goes on, this LED goes on.
It lights green when inputs signals are detected and it lights red when output signals are sent.

11. Serial Communication Connection Cable
This system guarantees enhanced quality for high-speed communication, and is designed to be
connected with LAN cables suitable for 100BASE and 1000BASE.
These are standard cables, easy to find and cheap. Therefore, we do not include these cables with our
products.
To select cables you need to connect, make sure they meet the following specifications.
Wiring standard: TIA/EIA-568-B
Category 5 (CAT5)
Enhanced category 5 (CAT5e)
Category 6 (CAT6)
UTP (UnShieldedTwistedPair) cables or STP (ShieldedTwistedPair) cables that meet the
specifications above.
The higher the standard the cables meet, the more the communication quality will be improved. To use
the board in an area with excessive electrical noise, use shielded cables (STP).
Observe the following when connecting your system.
1) Total serial line length
This system employs a multi-drop connection method. The maximum total extension distance of the
line varies, depending on the data transfer speed and the number of local boards that are
connected.
- Max. 100 m (Transfer speed; 20 Mbps with 32 local boards connected)
- Max. 50 m (Transfer speed; 20 Mbps with 64 local boards connected)
- Max. 100 m (Transfer speed; 10 Mbps with connecting 64 local boards connected)
2) Minimum cable length
The shortest cable must be at least 60 cm long.
3) Do not mix cables of different types and model in the same serial line.
4) Keep the total serial line length as short as possible.
5) If you are using shielded cables, do not connect the shield on both ends to the FG terminals.
Connecting only one end of the shield on each cable will improve noise immunity.
