When planning a CompactLogix system, you need to consider the following:
• The CompactLogix controller is always the leftmost module of the system.
• The controller must be within the four power modules of the system. Some I/O modules are the most A maximum of eight modules can be separated from the power module. For details, see 1769 I/O module documentation.
• The 1769-L32E controller supports up to 16 I/O modules,
The 1769-L35E controller supports up to 30 I/O modules. Two kinds of control
The device can use up to three I/O groups and two expansion cables.
• Each I/O slot requires independent power supply.
• Only one controller can be used in a CompactLogix system.
• The end of the communication bus needs to use the 1769-ECR right end cover or 1769-ECL Left end cap finish.
