Preface
Standard ControlLogix
Systems The ControlLogix system is a modular system that requires a 1756 I/O chassis
that houses various modules. Chassis are available with 4, 7, 10, 13, and 17 slots
for standard applications where temperatures range from 0…60 °C
(32…140 °F). You can place any module into any slot.
The chassis backplane provides the following features:
• A high-speed communication path between modules
• Power distribution to each module housed in the chassis
• Messages passed between multiple controllers housed in the chassis
• Messages passed between and through multiple communication-interface
modules housed on the chassis
ControlLogix-XT Systems The ControlLogix-XT products include power, control, and communication
system components that, when used with FLEX I/O-XT™ products, provide a
complete control system solution that can be used in environments where
temperatures range from -20…70 °C (-4…158 °F). Chassis are available with 4, 5,
and 7 slots.
When used independently, ControlLogix-XT systems can withstand
environments where temperatures range from -25…70 °C (-13…158 °F) for
equipment designated as ‘XT’ and -25…60 °C (-13…140 °F) for equipment
designated ‘LXT’.
These installation instructions describe how to install the following components
of a ControlLogix system:
• Standard ControlLogix chassis
• Standard ControlLogix power supplies
• ControlLogix-XT™ chassis
• ControlLogix-XT power supplies
• ControlLogix redundant power supplies
• ControlLogix chassis adapters
