Special Relay(SB)
Set the start device where SB and SW are transferred. SB and
SW can be automatically transferred to a device in a CPU module
without using a program.
Special

Retry Count Set the number of retries when a communication failure occurs.
Set the number of slave stations that return to the system
Automatic operation by a single link scan after the stations are disconnected
Reconnection due to a communication failure.
Station Count Setting a larger number extends link scan time of when the
station returns.
Set the station number for the standby master station.
Set the number of the station that controls a CC-Link system
Standby Master

Whether to synchronize the link scan with the sequence scan of a
CPU module or not can be selected. (
8.3.5)
• Asynchronous
A link scan does not synchronize with a sequence scan. Input
transmission delay time is shortened.
Scan Mode Setting
• Synchronous
A link scan synchronizes with a sequence scan. (The
sequence scan and link scan start simultaneously.)
Output transmission delay time is shortened.
Because of the synchronization, extended sequence scan time
increases link scan time.
Delay Time Setting Set 0.
