The 5069-L310ERMS2 is a high-performance safety controller from the Compact GuardLogix 5380 family. It provides integrated control for both standard and safety-related industrial applications, achieving safety ratings up to SIL 2 / PLd (Category 3). This controller is designed for machine builders who require a single, compact unit to manage complex logic, high-speed I/O, and motion, while simultaneously ensuring functional safety for personnel and equipment.

Core Capabilities
1. Integrated Safety & Standard Control
The 5069-L310ERMS2 eliminates the need for a separate safety PLC. It uses a "1oo2" (one out of two) internal architecture to monitor and execute safety functions. In Studio 5000, safety logic is kept in a dedicated "Safety Task" with restricted access, ensuring that standard code modifications do not inadvertently affect safety signatures.
2. Integrated Motion on EtherNet/IP
The "M" in the catalog number signifies integrated motion support. It can coordinate up to 4 axes of CIP Motion, allowing for synchronized control of Kinetix servo drives. Crucially, this includes CIP Safety over EtherNet/IP, enabling safe speed, safe direction, and safe torque off (STO) functions to be managed over the same network cable as the standard control data.
3. High-Speed Performance & Dual Gigabit Ethernet
-
Dual-IP Mode: Allows for the physical separation of safety/I/O traffic from the higher-level enterprise network, which is vital for maintaining safety determinism and cybersecurity.
-
DLR Support: Supports Device Level Ring topologies to ensure that a single cable failure does not drop the safety connection, preventing nuisance trips.
Technical FAQs
What is the difference between the 5069-L310ERM and the 5069-L310ERMS2?
The L310ERM is a standard controller with motion support. The L310ERMS2 adds a dedicated 0.5 MB safety memory partition and the internal diagnostics required to be certified for SIL 2 safety applications.
Can I use standard 5069 I/O modules with this controller?
Yes. You can mix standard 5069 I/O modules for non-safety tasks and 5069-IB8S / OBV8S safety modules for safety tasks in the same local rack or on the same remote EtherNet/IP network.
Does this controller require a safety partner module?
No. Unlike the older 1756 GuardLogix systems that required a primary and a safety partner, the Compact GuardLogix 5380 series (like the L310ERMS2) is a self-contained safety controller.
Engineering & Installation Guide
-
Safety Signatures: Once the safety logic is validated, the controller generates a unique safety signature. Any change to the safety code changes this signature, providing a clear audit trail for regulatory compliance (e.g., OSHA or CE).
-
Power Architecture: Like other 5069 units, it requires MOD Power (for logic) and SA Power (for field-side I/O power). Use high-quality DC power supplies to ensure the safety bus remains stable.
-
Environmental Considerations: The controller is designed for an operating temperature range of 0 to 60°C. In safety applications, ensure that cabinet cooling is adequate, as the safety processor performs intense internal self-diagnostics that generate additional heat.
