Note(１) FG is equivalent to the function ground, so we recommend a dedicated ground or shared ground.
(1) Please use the connection cable only for Ver.1.10 compatible CC-Link (Triplex twisted-pair cable witha shield). And, mixture of the cable of a different kind cannot be performed.
In case it is intermingled, a normal data communication is not guaranteed.
Please refer to an about a cable. (CC-Link association, partner product-information, cable connector)(2) Please be sure to connect a terminating resistance to the unit of the both ends of a CC-Link system.
Master side：Please connect a terminating resistance between DA-DB. 110Ω (1/2W)
Slave side ：When the 17th terminal (DB) and 19th terminal (Ter.) are short-circuited, a terminating
resistor (110Ω) is connected inside.
(3) Please shielding wire of CC-Link cable is connected to SLD of each unit. And, please do D-classgrounding (with ground resistance of 100Ω or less) of FG. (SLD and FG connected inside the unit.)

Remote station,①Ready① After the slave station power supply is OFF to ON, the remote station, Ready changes from 0 to 1.
② Write the control command to the remote register (RWw) of the master station.
③ Various data is updated for each link scan.
<Note> If communication is stopped halfway due to a setting change, reset the power or reset the device(setting mode：CPU reset).
Refer to the instruction manual for how to reset the device.

3.4 Error communication (Error status / Reset request)
Perform this when the slave station notifies / cancels the error occurrence.
An error will occur if data is written to an unused area of the remote output (RY) or remote register(RWw). And, an error occurs if the control command is other than 0E0EH (no control：normal), 0E37H(on command), and 0EC8H (off command).

And, the remote station, Ready② When the error status flag changes from 0 to 1, check and clear the unused area data and check thecontrol command value. Then, please give an error reset request flag as 0 to 1 at the case of a slave
station and resumption of communication.
③ After an error reset request flag's changing into 0 to 1, an error status flag is 1 to 0.
④ After an error status flag's changing into 1 to 0, please set an error reset request flag to 1 to 0.
⑤ After an error reset request flag's changing into 1 to 0, the remote station, Ready is 0 to 1.
