Flexlogic™ is the powerful UR-platform programming logic engine that provides the ability of creating customized protection and control schemes based on information measured locally by the N60 and received from remote N60s sent to it over the communications network. With Flexlogic™, the N60 can use the status of measured inputs, along with the output of the protection elements, FlexElements™ and FlexMath™ summators, in Boolean logic equations to perform automated function for customized special protection schemes. |
|
|
 |
| |
The N60 contains Flexlogic™ and FlexMath™ equations that allow for creating automated wide area protection and control schemes, remedial action schemes, and other special protection applications. |

The UR Switch provides a simple way to add fully-managed Ethernet networking to your relays and devices without the need for additional hardware or a dedicated communications cabinet.
The UR Switch includes all the management and features that come with all MultiLink managed switches, and can be easily integrated into a network that has other Ethernet switches.
When used in a ring topology with other UR switch modules or MultiLink switches, the UR Switch can be configured to use MultiLink’s Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch. Learn More |

Access Control
Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond.
The UR Family provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications. |
| |
Intrusion Detection
Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity.control factor that can lock or unlock a device for configuration changes and other modifications. |

|
Auditing and Reporting
With the Security Audit Trail reporting feature and support for Event logging of key
activities such as configuration changes, Multilin devices can help ensure device and
protection system integrity, and perform forensic auditing of activities and changes
for compliance. |
