Security - enabling NERC CIP compliance

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 3 Series 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.

  IEEE 1588 synchronizes time between different nodes on an Ethernet network when precise time synchronization is required, and IRIG-B allows time stamping of events to be synchronized among connected devices within 1 millisecond.

   

• Trip/Close Coil Monitoring

  The 350 can be used to monitor the integrity of both the breaker trip and closing coils and circuits. The supervision inputs monitor both the auxiliary voltage levels, while the outputs monitor the continuity of the trip and/or closing circuits, by applying a small current through the circuits.

Advanced Communications

The 350 incorporates the latest communication technologies, making it the easiest and the most flexible feeder protection relay for use and integration into new and existing infrastructures. The 350 relay provides the user with one front USB and one rear RS485 communication port. Also available with the 350 is a rear communication port with Ethernet Fiber and Copper. For configurations requiring PRP and HSR redundancy protocols, the 350 provides two rear Fiber ports. Through the use of these ports, continuous monitoring and control from a remote computer, SCADA system or PLC is possible.

The 350 provides optional Parallel Redundancy Protocol (PRP) and High Availability Seamless Ring (HSR) according to the IEC 62439-3 standard that defines two protocols to increase network availability by reducing failover time to zero. Both ports are capable of simultaneously supporting the following protocols: Modbus TCP/ IP, IEC 61850, DNP3 or IEC 60870-5-104, IEEE 1588, SNTP and OPC-UA.

Link Loss Alert (LLA) function detects any issue with one port and switch to the other one in case of failure.

The 350 protection relay chassis used with a draw out relay is available separately, for use as a partial replacement or in test environments. The draw out relay with no chassis is also available to order as a spare unit.

Application Flexibility & Ease of Wiring 

Removable terminals ease wiring and in-system testing or troubleshooting.

User Interface

Traditionally, retrofitting or upgrading an existing relay has been a challenging and time consuming task often requiring re-engineering, panel modifications and re-wiring. Similar features and form factor of some models of MII family devices allow users to replace their existing relays with 3 Series relays with enhanced protection and control features and advanced communications.

The SR3 Enervista Setup software allows users to create new setting files based on existing MIFII and MIVII setting files and can be uploaded to a 350 relay with a compatible model number. Retrofit is smooth and simplified with minor wiring or switchgear modifications.
