● Connect the terminating resistors between the DA and DB terminals.
● Connect the shielded cables of a CC-Link dedicated cable to the SLD terminal through the FG terminal. Then ground the
cables at both ends with a ground resistance of 100 or less. The SLD and FG terminals are connected inside.
● No restrictions apply to the connection order of a master/local module. (The cables need not be connected in the order of
station number.)
● The star topology cannot be used. Note, however, that the T-branch connection can be used. (
