Set the instruction code for execution of operation mode rewrite, Pr. read/write,
error reference, error clear, etc. (Refer to page 71) Set "1" in RYF to execute the
corresponding instruction after completing the register setting. "1" is set in RXF
after completing the execution of the instruction.
When a value other than "0 (100)" is set in Pr. 544 CC-Link expansion setting, upper
eight bits are link parameter extended setting.
Example) When reading Pr. 160, instruction code is H0200.
Set the data specified by the RWw2 instruction code. (When required)
Set "1" in RYF after setting RWw2 and this register.
Set zero when the write code is not required.
Set the monitor code to be monitored. By setting "1" in RYC after setting, the
specified monitored data is stored in RWr . (
to 7))
Set how many fault records in past to be read. Back to eight fault records in past
can be read. (lower 8bits is H00)
Upper: H00 (latest fault) to H07 (eight faults in past)/lower: H00
When H08 to HFF are set, fault record becomes an unfixed value.
