GOOSE subscription supervision (ALGOS)
ALGOS reports the status of GOOSE communication to a client according to IEC 61850.
There should be one instance of ALGOS in an IED for each data set that the IED receives from other
IEDs. Each ALGOS reports the status of the receiving GOOSE communication.
All attributes, both Mandatory and Optional, according to IEC 61850-7-4 Ed. 2.0 are supported.
Functionality
The ALGOS supervise the communication and reports the status on the attributes.
