Application of ENIP-2 and ENMV-1 in control systems can help to resolve some additional issues, such as interlocking of switchgear, e.g. disconnectors or circuit breakers. ENIP-2 and ENMV-1 with IEC 61850 support are used for interlocking.
The devices communicate with each other using GOOSE messages that contain binary values describing the state of the switchgear. Those values are used as inputs for logical expressions, which are bound to digital outputs that control the switchgear. The logical expressions are configurable.
