IEC 61850 is a standard for communication networks and systems in substations. Based on Ethernet protocol, it is a standardized method of communication, developed to support integrated systems composed of multi-vendor, self-describing IEDs (Intelligent Electronic Devices) that are networked together to perform real-time protection, control, measurement, and monitoring functions. IEC 61850 is widely used in critical applications, for example, oil and gas, or data centers.
The IEC 61850 for MasterPact MTZ Digital Module provides the following MasterPact MTZ circuit breaker data over an Ethernet network in conformance with IEC 61850 MMS (Manufacturing Message Specification) communication protocol:
oClass 1 energy metering
oElectrical measurements
oStatus
oControl
The IEC 61850 MMS communication protocol helps to integrate low voltage circuits breakers in medium voltage installations without the need for an additional gateway.
For more information, refer to DOCA0162EN MasterPact MTZ - IEC 61850 Communication Guide.
The IEC 61850 for MasterPact MTZ Digital Module is an optional Digital Module, which can be purchased and installed on a MicroLogic X control unit.
The IEC 61850 for MasterPact MTZ Digital Module is compatible with:
oMicroLogic 2.0 X, 5.0 X, 6.0 X, and 7.0 X control units for IEC standard
oMicroLogic 3.0 X, 5.0 X, and 6.0 X control units for UL standard
oMicroLogic X control units with firmware version greater than or equal to 004.000.000. Earlier firmware versions need to be updated.
The MasterPact MTZ IED (Intelligent Electronic Device) is composed of:
oOne MasterPact MTZ1, MTZ2, or MTZ3 circuit breaker
oOne MicroLogic X control unit with IEC 61850 for MasterPact MTZ Digital Module installed
oOne IFE or EIFE Ethernet interface
oOne or two IO modules (optional)
Data through IEC 61850 communication is available on a remote controller through the following communication interfaces:
oIFE Ethernet interface
oEIFE Ethernet interface
