Multi client access to BRCB
It is possible to access and configure the same BRCB
from different clients, however, it is recommended that
each BRCB be accessed and configured by only one
client.
Note the following restriction: The first client to enable a
BRCB establishes the “minimum MMS PDU size”
required for this BRCB. This BRCB can then be enabled
by any client which has the MMS PDU size at least as
big as the established “minimum MMS PDU size” for that
BRCB.
This restriction is required since the initial use may have
left buffered reports in the BRCB. The “minimum MMS
PDU size” was used for segmentation of the reports. If a
client enable the BRCB with a smaller “minimum MMS
PDU size”, the reports stored in a buffer cannot be sent
to this client due to their larger size.
Description
Value / Clarification
Note about internal variable “Remote Device” and GOOSE
validity checks
For each incoming GOOSE in the device there is an
associated internal variable called “Remote Device”. This
variable can have value ONLINE or OFFLINE.
Value ONLINE means that the incoming GOOSE messages
from the configured sender have been positively
validated by MAC destination, gocbRef, datSet and goID.
Value OFFLINE means that there are no GOOSE messages
from configured sender or that incoming GOOSE
messages from this sender have been invalidated by MAC
destination or gocbRef or datSet or goID.
The variable “Remote Device” can have value ONLINE (it
has been validated by MAC destination, gocbRef, datSet
and goID) but if the GOOSE message has been invalidated
by confRev or ndsCom or numDatSetEntries or allData or
if the order of data set elements is not correct then the
incoming data from GOOSE message is ignored.
