RemoteI/O & RemoteMotion

Motionnet Local Output Board MNET-D304 YA7084-0/1

1. Preface

Thank you for purchasing our output board, a local board from our Motionnet ultra-high speed serial

communication system series.

□

The MNET-D304 board you have purchased is a 32 point parallel output 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.

RemoteI/O & RemoteMotion

Motionnet Local Output Board MNET-D304 YA7084-0/1

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-D304. 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 Output Board MNET-D304 YA7084-0/1

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.

Output

- Number of output points: 32 points

- Isolation method: Photocouplers

- Output interface: Darlington transistor output

Common output specifications

8 output 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 communication.

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.
