Number of nodes Max. 64 stations (max. number of connections per group: 16 stations)
Number of usable stations: 1 station per MR-JE-_C servo amplifier
Standard response time
(Note 1)
(Link scan time/timeout time
(Note 2, 3))
10 ms
Note 1. Standard response time refers to the time from when the servo amplifier receives a command from the master station until
when it returns a response to the master station.
2. Calculate the link scan time as follows. Also, use the standard response time for Ns.
MELSEC iQ-R/MELSEC-Q/L: Ls = Ns + Nm
MELSEC iQ-F: Ls = SM + {(Ns + Nm)/SM}
Ls: Link scan time, Ns: Response time of slave station, Nm: Request time of master station, SM: Sequence scan time
3. Check the current link scan time (when all the slave stations are in a normal state) using the CC-Link IE Field Network Basic
diagnosis function. Then, set the timeout time approximately 5 times the link scan time (example: 50 ms when the current link
scan time is 10 ms).

2.1 Summary
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 library to drive a servo motor and return monitor
data.

2.2 Message format
The following shows the request message format to be used when the master station (controller) sends a
message, and the response message format to be used when the slave stations (servo amplifiers) return a
message.
Messages are sent by using UDP/IP.

2.3 Link device
In cyclic communication, communication data of the request message and response message is read as
object data (RWwn, RWrn, RYn, RXn) of the servo amplifier. Table 2.1 and 2.2 list initial settings.
The setting of the response message can be changed. When changing it from the initial setting, refer to
section 7.2.3.
