Place 1769 I/O Modules in a 1768 CompactLogix System
You can use up to eight 1769 I/O modules in the same bank as the 1768 power
supply. 1769 I/O modules must be placed to the right of the controller. Additional
1769 I/O modules may be placed in remote 1769 banks.
For more information on placing I/O modules in the 1768 CompactLogix system,
see the 1768 CompactLogix Controller User Manual, publication 1768-UM001.
IMPORTANT
Because the 1768 CompactLogix power supply works with the controller to
power a 1768 system, the distance rating in a 1768 CompactLogix system is
different than in a 1769 CompactLogix system.
In the 1768 system, the distance rating is the distance between 1769 I/O
modules and the controller. In the 1769 system, the distance rating is the
distance between 1769 I/O modules and the power supply.
