(6) Details of the remote register
The following device numbers are for the station number 1.
For the station number 2 and later, the device numbers are different. (Refer to the manual for the CC-Link master module for
the correspondence between device numbers and station numbers.)

Set the monitor code of the monitoring item. (Refer to page 108) Turning ON the RYC signal
after setting this register sets the monitor data to RWr0/RWr1.
Set an instruction code (Refer to page 114) for an operation such as parameter read/write,
alarm reference, and alarm clear. Turning ON the RYF signal after setting this register
executes the instruction code. The RXF signal turns ON after the instruction code execution is
completed.
When a value other than "0" is set to Pr. 544 CC-Link extended setting, upper 8 bits are used for
the link parameter extended setting.
Example) Reading of Pr. 300  The instruction code is 0300H.
Set data for the instruction code set in RWw2. (When required)
Turn ON the RYF signal after setting RWw2 and this register.
Set "0" when the write data is not required.
Set the monitor code of the monitoring item. Turning ON the RYC signal after setting this
register sets the monitor data to RWr. ( indicates a register number. (RWr4 to 7))
Turning ON the RYC signal sets the monitor value to the lower 8 bits of the specified monitor code
(RWw0).
Turning ON the RYC signal sets the monitor value to the upper 8 bits of the monitor code
(RWw0) except when "0" was set to the upper 8 bits.
Turning ON the RYF signal sets the reply code, which corresponds to the instruction code of
RWw2. The value "0" is set for a normal reply, and a value other than "0" is set for errors with
data, mode, and other.
