Introduction

A 1756 GuardLogix® controller is a ControlLogix controller that also provides the ability to perform safety functions. You must use a primary safety controller and a 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 is a part of the system, is automatically configured, and requires no user setup. With the introduction of the GuardLogix 5580 controller, users can achieve up to SIL 2/PLd (Category 3) with a single controller and the use of the safety task and safety I/O. During development, safety and standard have the same rules; multiple programmers, online editing, and forcing are all 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 SIL3. If no safety partner is present, the safety integrity will be SIL2. 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 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.
