An Example of a Completed I/O Configuration

To transfer data using the SLC to SCANport module, you need to be
familiar with how the SLC I/O image table represents the internal
data I/O mapping and how the input and output image channel status
bits are defined.

When the SLC to SCANport module is configured as a basic mode
module, the internal data I/O mapping is represented within the SLC
image table as the following:

Channel 2 Cmd

Channel 1 Cmd

Reserved

Channel 3 Cmd

Logic Command Channel 1

Analog Reference Channel 1

Logic Command Channel 2

Analog Reference Channel 2

Logic Command Channel 3

Analog Reference Channel 3

Channel 2 Stat

Channel 1 Stat

Channel 3 Stat

Logic Status Channel 1

Important: Different SCANport devices may define different

meanings for the bits in the Logic Command and Logic
Status fields. They may also use the Reference and
Feedback differently. Refer to the manual for the
specific SCANport device for more information.
