Advanced
The scanner module allows each node’s slave data to be broken up
(segmented) into separate input image areas. This capability lets you group
data from multiple slave nodes into contiguous memory locations. This is
simply an ease-of-use feature. For maximum performance, do not segment a
slave device’s data.
Output Tab
The output tab dialog lets you define how data from the scanner module is
mapped to the outputs of the slave devices.
