MAPPING GOOSE MESSAGES TO VIRTUAL INPUTS

Each GOOSE signal contained in a subscribed GOOSE message can be mapped to any of the 32 virtual
inputs within the PSL. The virtual inputs allow the mapping to internal logic functions for protection control,
directly to output contacts or LEDs for monitoring.
An IED can subscribe to all GOOSE messages but only the following data types can be decoded and
mapped to a virtual input:
● BOOLEAN
● BSTR2
● INT16
● INT32
● INT8
● UINT16
● UINT32
● UINT8

IEC 61850 GOOSE CONFIGURATION

All GOOSE configuration is performed using the IEC 61850 Configurator tool available in the MiCOM S1
Agile software application.
All GOOSE publishing configuration can be found under the GOOSE Publishing tab in the configuration
editor window. All GOOSE subscription configuration parameters are under the External Binding tab in the
configuration editor window.
Settings to enable GOOSE signalling and to apply Test Mode are available using the HMI.

ETHERNET FUNCTIONALITY

Settings relating to a failed Ethernet link are available in the COMMUNICATIONS column of the IED's HMI.
10.9.1

ETHERNET DISCONNECTION

IEC 61850 Associations are unique and made between the client and server. If Ethernet connectivity is lost
for any reason, the associations are lost, and will need to be re-established by the client. The IED has a
TCP_KEEPALIVE function to monitor each association, and terminate any which are no longer active.
10.9.2

LOSS OF POWER

The IED allows the re-establishment of associations without disruption of its operation, even after its power
has been removed. As the IED acts as a server in this process, the client must request the association.
Uncommitted settings are cancelled when power is lost, and reports requested by connected clients are
reset. The client must re-enable these when it next creates the new association to the IED.
