ControlLogix L7x Controller Overview

ControlLogix L73 and –L75 controllers provide memory, speed and processing
capabilities to meet the demands of basic plant floor applications to high
performance process and motion applications. As part of the Integrated
Architecture system, they use the same programming software, network protocol
and information capabilities as ControlLogix L6x controllers to provide a common
control engine with a common development environment for all control disciplines.
