Share Article

GarrettCom™, Inc.'s, Magnum™ 6K Switches, running MNS-6K and MNS-6K-SECURE software, were confirmed compliant with IEC 61850 GOOSE (Generic Object Oriented Substation Events)messaging standards based on IEC 61850 functional testing recently completed by KEMA.

GarrettCom™, Inc.'s, Magnum™ 6K Switches were confirmed compliant with IEC 61850 GOOSE messaging standards based on IEC 61850 functional testing recently completed by KEMA. The testing was performed on Magnum 6K switches running MNS-6K and MNS-6K-SECURE software, which includes support for the IEEE 802.1D-2004 standard for Rapid Spanning Tree Protocol (RSTP). KEMA is a well-respected consulting company that provides consulting, testing and certification services for the power industry worldwide. GOOSE (Generic Object Oriented Substation Events), a part of the IEC 61850 standard for substation automation, is a control model mechanism in which any substation data format can be grouped into a data set and transmitted. It is typically used for high-priority protection-related messages.

The test groups included VLAN handling and priority tagging, where GarrettCom received a "Passed" rating, and Rapid Spanning Tree for network fault recovery. The Rapid Spanning Tree tests verified recovery of a single communication failure and measured recovery time and packet drops under a variety of packet sizes, network loads, and forced disconnections in the network ring structure. The fault recovery time of 4-6 ms., with no packet loss, is the fastest recovery time available on a hardened switch or router in the industry. The superior performance was achieved without the use of proprietary code; the Magnum RSTP implementation used in the company's 6K Switches and DX Routers is compliant with industry standards and interoperable with most other vendor's RSTP software.
