method thereby dividing the network into sectors called power network areas. Each
PML630 is responsible for the load-shedding action in its respective area, based on the
power source capabilities and inter-power network area connectivity status. The
coordination of load-shedding actions between the PML630 IEDs is handled by
suitable parameterization. This arrangement of multiple PML630 IEDs in a peer-to-
peer method is called cPMS - LS configuration B.
The PML630 IEDs communicate with each other also using IEC 61850 GOOSE.
Likewise, cPMS - LS configuration B is also a feature in PML630. The Configuration
B is always built up over and above the Configuration A and hence the latter is a
prerequisite.
The maximum recommended number of PML630 IEDs in a peer-to-peer mode in
Configuration B is three.
The power network areas would be connected to each other through their grid 1 or grid
2 power source connection points.

Local HMI

The LHMI is used for setting, monitoring and controlling the device. The LHMI
comprises the display, buttons, LED indicators and communication port.
