Preface X-NET introduction
X-NET protocol stack which is developed by XINJE Company committed to the automation
production network. X-NET supports different physical media and networks. X_NET refers to
OSI seven layers network protocol, it defines the service and function of each layer and make the
network more efficient and simple.
The physical protocol supported by XD3 and XDM including RS485, RS232, OC (optical circle),
USB_PHY. The network protocol includes TBN (Token Bus Net), OMMS (one master multi slave
net). TBN is fit for embedded equipment network, the advantage includes real-time and
multi-master. OMMS is fit for master-slave network, the advantage is wide applicability, but the
response time is longer than TBN.

TBN belongs to industry fieldbus. It is token structure, any node in the network has access rights
(token), any node who got the token can send message to other node. It doesn’t have master and
slave. It makes the data access efficient and flexible.
OMMS focus on the connection between upper device and embedded equipment. The connection
between equipments is permitted. The PLC connection with programming software and network
configuration software uses OMMS protocol.
The MCP (motion control protocol) based on OMMS makes the multi-axis controlling simple.
8-axis 2ms control period can meet most of motion control needs. It needs one PLC and 8 servo
drives to make the project, no need special communication module.
X-NET includes X-NET fieldbus and X-NET motion fieldbus.
X-NET fieldbus is applied to XD series PLC and TG/TN series HMI.
X-NET motion fieldbus is applied to XD series PLC and DS3E series servo drive.

1 X-NET fieldbus
1-1. Function summarize
1-1-1. Introduction
X-NET fieldbus is used between XD series PLC or XD series PLC and TG/TN series HMI.
The filebus has the advantages of intelligence and digitize, the max speed can up to 3M. It can
work through RS485 and OC (optical fiber) for long distance and high speed communication. It
has faster speed and better stability than Modbus protocol.
1-1-2. Wiring mode
Please use serial connection for TBN protocol running on RS485. As the star connection has low
driving ability and short communication distance, strong signal reflection, higher communication
error rate. It is not recommended to use star connection.
TBN_RS485 baud rate range is 600bit~3Mbit. The communication speed and medium are related
to the local environment. As the TBN_RS485 using electrical signal to transfer data, there are
some requirements for the communication distance. Please refer to the following table.
Please use copper shielded wire up 0.3mm2for TBN_RS485 fieldbus.
The relationship between TBN_RS485 filedbus cable length and baud rate:
Baud rate
Wire length
9.6-187.5Kbit/s
1000m
500Kbit/s
400m
1.5Mbit/s
200m
3Mbit/s
100m
TBN_RS485 cable is recommended to use shielded twisted pair cable (ASTP-120Ωfor
RS485&CAN, 21AWG, red blue twisted pair), according to the standard UL758-2008 &UL1581.
The shileded layers includeAluminium foil 100% and tinned copper net 70%.
The following diagram is the cable profile:
There are three kinds of connection methods for PLC.
1. PLC RS485 port on the main unit
2. PLC expansion BD board XD-NE-BD
3. PLC expansion ED board

Connection method 1:
Terminal A is RS485+, terminal B is RS485-. ConnnectAto A, B to B.
Note: RS485 port can communication through Modbus_RTU or X-NET. Please choose the mode
in XINJEConfig software. As the communication effect of RS485 port on the PLC is not better
than BD board, it is not recommended to use PLC RS485 port for X-NET communication.
Connection method 2:
There are four terminals including A, B, SG(signal ground), FG(shielded ground) on expansion
BD board XD-RS485-BD. Normally, X-NET needs to connect terminal A and B, the shielded
layer connects to FG. If there is requirements for anti-interference, such as motion control fieldbus,
it needs to connect terminal A, B, SG.
XD-RS485-BD has switch to set terminal resistor. The default setting is switch OFF(left) without
terminal resistor. If XD-RS485-BD is at the head or end of the filedbus, it needs to add 120ohm
terminal resistor at both end, the switch must be ON (right).
Note: RS485 port of XD-NE-BD can communication through Modbus_RTU or X-NET. Please
choose the mode in XINJEConfig software.
Connection method 3:
Connect through the expansion ED board on the left side of PLC.

Note: the ED board is in developing.
When TBN runs on OC, the station connection wire is optical fiber. The last station sending
terminal connects to the receiving terminal of the first station to make the loop network. The
optical signal has strong anti-interference ability. But the optical fiber is easy to broken and
complicated to make the pigtail, this limits the developing of optical fiber. TBN_OC supports
600bit~3Mbit baud rate.
As the RS485 device driving ability and conversion speed of photoelectric module, the node
quantity in the TBN network must be less than 32.
1-1-3. XINJEConfig software
The using steps of XINJEConfig:
For example, two XD3-32T-E communicate with each other through RS485 port based on X-NET
protocol.
Note: Please connect PLC with PC through USB cable before matching the PLC by software.
Make sure to install the USB driver before using.
USB cable
Open the XINJEConfig software, click config/find device.

Choose the com port connected PLC, device type is PLC.
If the communication between PLC and PC is error, there will show below error. Please restart the
software and configure again.
Click ok to back to main window. Then click config/single deivce/com port.

As the PLC RS485 port is serial port2, here we choose no.2 for comportNo. The protocol is
X-NET. The physical layer is RS485.
NetID: the network number of the two PLC. The device net ID in the same network must be the
same. Here we set it to 1.
StationID: each PLC station number in the network. The two PLC station number is 1 and 2.
Net type:
TBN--- PLC communicate with PLC
TBN or HDN--- PLC communicate with HMI
HDN--- PLC communicate with servo.
Baud rate: here we set it to 1.5M
TokenCycle time: the time of each station in the network cycle once, the unit is ms. Here we have
two PLC, so the time set to 10ms.
Max station number: the max device numbers in the network.

Click “write config”, it will show read success window.
Click ok to back to the main window. Cut off the PLC power and power on again to make the
setting effective.
Then click config/single device/route.
It shows the Form_RouteTb1 window.
Click “read”, it shows read success.

Click ok, the Form_RouteTb1 window shows the subnet routing.
The subnet ID is the same to the netID. The communication port is the PLC physical terminal,
RS485 port number is 2. Gateway address: the default setting is 0.
Click “write”, it will show write success. Then click ok. Please cut off the PLC power and power
on again to make the setting effective.
Note:
1. After changing the device, it needs to configure again.
2. If it shows the error “there are some errors when communicating to XnetServer”, please restart
the software and configure again.
1-2. Communication instruction
X-NET instructions include bit read and write, register read and write.
The communication instruction operand explanation:
1. Target net ID: all the devices construct the communication network. The ID of the network is
the target net ID.
For example: 5 PLCs will communicate with each other in the network through X-NET protocol.
User can define the net ID for this network.
2. Target station number: the station number of target device in the network.
For example: PLC connects to 3 frequency inverters, the frequency inverter station number is 1, 2,
3, and PLC station number is 4. The PLC will read the parameters of three inverters. Station
number 1, 2, 3 are the target station number of PLC.
3. Target object type: the target device is coil or register.
