ControlLogix System
ControlLogix System
A simple ControlLogix system consists of a standalone controller
and I/O modules in a single chassis. For a more comprehensive
system, use:
multiple controllers in a single chassis.multiple controllers
joined across networks.I/O in multiple platforms that is
distributed in many locations and connected over multiple I/O
links.

ControlLogix Enhanced Redundancy System
The ControlLogix controller supports redundancy. Redundancy
enables higher productivity by providing higher system availability
by switching control to a secondarycontroller chassis if the
primary redundancy module detects an event on any module in the
primary chassis.
ControlLogix firmware version 19.50 provides enhanced redundancy
for high-availability applications. See the Rockwell Automation
Support site for details ondownloading the firmware bundle
(V19.52Enh). ControlLogix Redundancy v19.50 adds support for:

Typical Applications
General Industry
-
Boilers / combustion control
Turbomachinery (compressors, turbines)
ESD (Emergency Shutdown)
Oil & Gas
Exploration and production (platforms, wells)
Transportation (pipelines, compressor stations)
Chemical
Specialty chemicals
Pharmaceuticals
Power (wind & traditional)
Boilers, turbines, generation
ExampleConfigurationControlLogixEnhancedRedundancySystem
Note that this example shows I/O control on both EtherNet/IP and
ControlNet networks. Either one or the other is required; you do
not need both.
GuardLogix Safety System
A GuardLogix controller is a ControlLogix controller that also
provides safety control. The GuardLogix system is a dual controller
solution you must use a 1756L6xS orL7xS primary controller and a
1756LSP or L7SP safety partner to achieve SIL 3 and Cat. 4/PLe. A
major benefit of this system is that its still a single project,
safetyand standard together. The safety partner controller is a
part of the system, is automatically configured, and requires no
user setup.
