1756-L73S/B Allen Bradley The controller has a conformal coating

ControlLogix 5580 and ControlLogix 5570 controllers support controller redundancy. In a redundant controller system, you need these
components:
• Two 1756 chassis, each with the same of the following:
– Number of slots
– Modules in the same slots
– Redundancy firmware revisions in each module
– Approved module firmware revisions for use within ControlLogix Redundancy systems.
• One 1756-RM2, 1756-RM2K, or 1756-RM2XT module per chassis that supports the following:
– One or two ControlLogix controllers of the same family. ControlLogix 5580 controllers support redundancy with Studio 5000
Logix Designer application, version 33.00.02 or later.
– For ControlLogix 5580 controllers, as many as seven EtherNet/IP communication modules.
– For ControlLogix 5570 controllers, as many as seven ControlNet or EtherNet/IP communication modules in any combination.
• One or two 1756-RMCx cables

During development, safety and standard have the same rules. Multiple programmers, online editing, and forcing are allowed. Once the safety
system is validated and the safety signature applied, safety memory is protected, the safety logic cannot be modified, and all safety
functions operate with SIL integrity. If the safety partner is present, the safety integrity will be SIL 3. If no safety partner is present, the
safety integrity will be SIL 2.
On the standard side of the GuardLogix controller, all functions operate like a regular Logix controller. Online editing, forcing, and other
activities are 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 system-wide integration and the ability to display safety status on
displays or marquees. For field device connectivity on EtherNet/IP or DeviceNet networks, use Guard I/O™ modules. For safety interlocking
between GuardLogix controllers, use EtherNet/IP 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 to add a layer of protection when exposed to harsh, corrosive
environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.
