Output Image - Configuration Words
Eight words of the SLC processor’s output image table are reserved
for the module. Output image words 0-7 are used to configure the
module’s input channels 0-7. Each output image word configures a
single channel, and can be referred to as a configuration word. Each
word has a unique address based on the slot number assigned to the
module.
Example Address - If you want to configure channel 2 on the
module located in slot 4 in the SLC chassis, your address would be
O:4.2.
