Before You Begin
Consider the following when planning your CompactLogix system:
• The CompactLogix controller is always the leftmost module in
the system.
• The controller must be located within four modules of the
system power supply. Some I/O modules may be located up
to eight modules away from the power supply. See the
documentation for your 1769 I/O modules for details.
• The 1769-L32E and 1769-L35E controllers support as many as
16 I/O modules in a maximum of 3 I/O banks with 2
expansion cables.
• Each I/O bank requires its own power supply.
• Only one controller can be used in a CompactLogix system.
• A 1769-ECR right end cap or 1769-ECL left end cap is required
to terminate the end of the communication bus.
