You’ll see this screen.
Notice that the 1769 system configuration software is now completely
filled in with the actual I/O modules, power supplies, cable, and end
cap. You can view the second bank by choosing the I/O Bank 2
Configuration tab. This layout matches the Hardware Setup on page
6-1.
Next, you’ll want to configure the individual I/O modules. When you
choose the Slot button next to each I/O module, you’ll see a screen
allowing you to view and modify the I/O data size, module keying,
and choose the state of each output (provided the module is an
output module) in the event that the SLC processor is placed in the
Program or Fault mode.
Modules requiring configuration, like analog I/O modules, must be
configured by choosing the Slot button.
Choosing I/O Data Size is useful when determining how the I/O data
is packed in the Logix5550 image table. Data Description shows you a
description of each word shown in the I/O Data Size dialog. By
default, discrete output modules use an output word and an input
word. The input word contains an echo of the output data. You could
disable this echo to save input image, but for this example we will
leave the echo enabled.
