GOOSE Subscription Status
The gateway’s GOOSE subscription verifies match of confRev in a manner
identical to the verification performed when enabling a report.
If the confRev does not match (unavailable, wrong type, different value), then the
GOOSE is not subscribed and an Event is logged in the Event Logger describing
the reason.
If the data type of confRev fetched from the IEC device is not RT_UNSIGNED,
then no event is logged.
The command, confRev must match what is running in the IED when the
gateway comes on-line with the current configuration, or the gateway does not
successfully subscribe to the GOOSE message.
The gateway does not check for a match of the GOOSE appid from the CID file
to the actual running IED when performing a GOOSE subscription.
IED Disconnect/Reconnect
If for any reason an IED disconnects from the network, the gateway continually
polls for the device and attempt to reconnect.
5.5.5 Control
Operate
Used by Direct control with normal security, SBO control with normal security,
Direct control with enhanced security, and SBO control with enhanced security to
write data to IED devices.
In the case where the logical node has (for example) Pos data that has SBOw,
Oper, and Cancel, you need to map the Oper structure only when wanting to
control that data. SBOw, Oper, and Cancel all refer to controlling the same Data
Attributes on the IED. The gateway automatically handles the select with value.
So although the SBOw and Cancel can be seen in the configuration software,
they should not be mapped. Only the Oper should be mapped.
The IEC 61850 Oper Structure has Data Attributes as defined by the standard.
When you make MMS Writes from the Modbus device to the IED, if you do not
populate all data elements of Oper, the gateway by default populates the other
data elements with 0 (zero). The exception to this is T which is always set to the
current time in the gateway.
The IEC 61850 Client driver needs to provide the following information to the
IED. These Data Attributes are available for you to select and set.
