750-637
The above Incremental Encoder Interface Module has a total of 6 bytes of user
data in both the Input and Output Process Image (4 bytes of encoder data and 2
bytes of control/status). The following table illustrates the Input and Output
Process Image, which have 4 words mapped into each image. Word alignment is
applied.
