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 cablewith a 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.)

<Note> If communication is stopped halfway due to a setting change, reset the power or reset thedevice (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, the remote station,② If the error status flag changes from 0 to 1, plaese check the data in the unused area and clear.
Then, please give an error reset request flag as 0 to 1 at the case of a slave station and resumptionof 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.
