Important: The size of the Reference ( Parameter 7- [Ref/Fdbk Size] )
and Datalinks ( Parameter 8- [Datalink Size] ) will affect
the size you configure for the network I/O. For example,
32-bit Datalinks requires twice as many words as 16-bit
Datalinks. Depending on your application, the configured I/
O size may vary.
Note the values in the Input Address and Output Address fields. These
are needed to develop a ladder program.
