2.1 Outline
CC-Link IE Field Network Basic is a standard Ethernet-based protocol used to perform cyclic communication
by the installed software without using a dedicated ASIC. You can establish a highly flexible system because
CC-Link IE Field Network Basic can be used together with TCP/IP communications.
Up to 64 axes of servo amplifiers (up to 16 axes of servo amplifiers per group) can be monitored by the
controller.
In the profile position mode, positioning operation can be performed based on the position data (target
position) given via the controller.
In the point table mode (pt), you can perform positioning operation by specifying the pre-configured point
table number (1 to 255) with a controller.
2.1.1 Features
(1) High-speed communication
High-speed communication can be established by cyclic transmission of not only bit data but also word
data.
The maximum communication speed is 100 Mbps.
(2) General-purpose Ethernet supported
Dedicated control wiring is unnecessary, and Ethernet network can be integrated.

2.3 Outline of CC-Link IE Field Network Basic protocol
In CC-Link IE Field Network Basic, a command that a master station (controller) sends to slave stations
(servo amplifiers) is called a request message, and a command that the slave stations (servo amplifiers)
send back to the master station (controller) is called a response message.
The master station (controller) sends the request message using the directed broadcast to all slave stations
(servo amplifiers). When the servo amplifier receives the request message, it acquires data for own station
and returns the response message to the master station (controller) using the unicast after the servo
amplifier response time. The servo amplifier response time differs depending on the command to send.
Use link devices (RWr, RWw, RX, and RY) for data communications. Sending and receiving the request
message and response message at a constant cycle allow the master station (controller) to perform link
refresh.
The servo amplifier reads the received data as an object dictionary to drive a servo motor and return monitor
data.
