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.
