The following table shows the aliases created for a scanner in slot 0 in the
ControlLogix chassis.
Notice that the alias names for the discrete outputs in the Export Alias
Creation table are the same as the alias names for the placeholders in the Alias
Creation for a Scanner in the ControlLogix Chassis table, but now point to I/
O outputs.
