Power Supply Distance Rating
CompactLogix 5370 L3 controllers and the Compact I/O modules have power
supply distance ratings. Power supply distance ratings determine how many slots
in a bank that a device can be from the power supply.
For example, a product with a power supply distance rating of four can only have
up to three slots between it and the power supply.
CompactLogix 5370 L3 controllers must be the leftmost device in the control
system, and the system only enables up to three modules between the controller
and the power supply. This graphic shows an example configuration.
