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 within four modules of the system power supply.
Some I/O modules may be up to eight modules away from the power
supply. See the documentation for your 1769 I/O modules for details.
• The 1769-L32E controller supports as many as 16 I/O modules and the
1769-L35E controller supports as many as 30 I/O modules. Both
controllers can use a maximum of 3 I/O banks with 2 expansion cables.
• The 1769-L32C controller supports as many as 16 I/O modules in a
maximum of 3 I/O banks with 2 expansion cables. The 1769-L35CR
controller supports as many as 30 I/O modules in a maximum of 3 I/O
banks with 2 expansion cables.
• The 1769-L31 controller supports 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.
