ControlLogix System Overview
13
The ControlLogix controller divides resources between a Logix CPU
and a backplane CPU.
Logix CPU and Backplane CPU
•
The Logix CPU executes application code and messages.
•
The backplane CPU communicates with I/O and sends and
receives data from the backplane. This CPU operates
independently from the Logix CPU, so it sends and receives I/O
information asynchronous to program execution.
Design
When you design a ControlLogix system, select:
•
I/O devices.
•
motion control and drives requirements.
•
communication modules.
•
controllers.
•
chassis.
•
power supplies.
•
software.
Install Hardware
To install a ControlLogix controller:
•
install memory options.
–
on a 1756-L55, install a memory board for additional memory.
–
on a 1756-L6
x
, install a 1784-CF64 CompactFlash card for
nonvolatile memory.
See the chapter Maintain Nonvolatile Memory.
•
connect the battery.
See the chapter Maintain the Battery.
•
install the controller in the chassis.
