Channel Configuration
Channel configuration words appear in the SLC processor’s output
image table as shown below. Words 0 to 7 correspond to module
channels 0 to 7.
After module installation, configure each channel to establish the way
the channel operates (e.g., thermocouple type, temperature units,
etc.). Configure the channel by setting bits in the configuration word
using your programming device. The SLC configuration words are
shown below.
