9. Enter the input and output size for the node on the network. The
number of words selected depends on the I/O to be communicated
with the node. In this example, the Node 2 PowerFlex 70 is set for all
I/O enabled which equates to 10 words of I/O

Words Input to PLC-5C
0-1 Logic Command / Reference
2-3 Datalinks A1 & A2 Out
4-5 Datalinks B1 & B2 Out
6-7 Datalinks C1 & C2 Out
8-9 Datalinks D1 & D2 Out
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.
