4.1.1  Link Refresh 

Link refresh refers to the reading and writing between the link relays and link 
registers in the sequence CPU module and the link data in the FA Link module 
attached to a local unit to synchronize the link data in the sequence CPU's data 
storage area with that in the FA Link Module. 
The sequence CPU reads data from the FA Link Module automatically so that data 
communications is transparent. 
Link refresh executes concurrently with instruction processing and does not affect 
the scan time.
