Description:
A GuardLogix® controller is a ControlLogix controller that also provides safety control. The GuardLogix system is a dual
controller solution—you must use a 1756-L6S/1756-L7S primary controller and a 1756-LSP/1756-L7SP safety partner
to achieve up to SIL CL 3/PLe/Cat. 4. A major benefit of this system is that it is still one project, safety and standard
together. The safety partner controller is a part of the system, is automatically configured, and requires no user setup.
During development, safety and standard have the same rules; multiple programmers, online editing, and forcing are all
allowed. Once the project is tested and ready for final validation, you set the safety task to a SIL 3 integrity level, which is
then enforced by the GuardLogix controller. When safety memory is locked and protected, the safety logic cannot be
modified and all safety functions operate with SIL 3 CL integrity. On the standard side of the GuardLogix controller, all
functions operate like a regular Logix controller. Thus, online editing, forcing, and other activities are all allowed.
With this level of integration, safety memory can be read by standard logic and external devices, like HMIs or other
controllers, minimizing the need to condition safety memory for use elsewhere. The result is easy system-wide
integration and the ability to display safety status on displays or marquees. Use Guard I/O™ modules for field device
connectivity on Ethernet or DeviceNet networks, and for safety interlocking between GuardLogix controllers use
Ethernet or ControlNet networks. Multiple GuardLogix controllers can share safety data for zone to zone interlocking,
or one GuardLogix controller can use remote distributed safety I/O between different cells/areas.
1756 GuardLogix controllers are available with a conformal coating. The conformal coating provides a layer of
protection against contaminants and humidity to help protect the assembly and extend product life in harsh, corrosive
environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.
In addition to the standard features of a ControlLogix controller, the GuardLogix controller has these safety-related
features.
