The remote input RX in the master station, and the remote input RX and remote
output RY in the local stations will either clear or retain the data from faulty
stations according to the setting. The remote register RWr in the master station
and the remote registers RWw and RWr in the local stations retain data from
faulty stations regardless of the setting.
POINT
When a data link faulty station is set as an error invalid station, the input data (remote
input RX and remote output RY) from that station is retained regardless of the setting.
(2) Setting method
The setting is performed at <<Parameter settings>> in the CC-Link Ver.2 utility.
For more details on the setting, refer to Section 8.2.5.
