quality. One signal is available inside the application to validate the reception of a
GOOSE message. The GOOSE signal is invalidated when GOOSE messages are
not received before 2*TAL(Time Allowed to Live).
GOOSE with TAL= 0 ms is treated as GOOSE with TAL = 100 ms
and accepted.
Note that the data sets that are used or referred to by GOOSE
control blocks can only include a data attribute once. In other
words, there may not be the same data attribute in more than one
data set.
When publishing a measured value, the user must take care of which measured
value data attributes are added to a data set. If the measured value is event-handled,
then one can add that value directly to the data set. If the value is not event-
handled, it is recommended to connect the value desired to be published to a
MVGAPC function block (in ACT) and then use the measured value given by the
MVGAPC.
MVGAPC - IEC 61850 generic communication I/ O functions have the event-
handled measured values (can be added directly to the data set).
Generic function blocks are provided to make available to the 61850 bus signals
that are not defined inside any of the available function blocks. Example of such
functions include:
• SPGAPC - IEC 61850 generic communication I/ O functions
• DPGAPC - IEC 61850 generic communication I/ O functions
• MVGAPC - IEC 61850 generic communication I/ O functions
Control
Of the different control sequences, the 'direct-with-normal-security' and 'SBO-
with-enhanced' security are supported (defined by the ctlModel parameter, IEC
61850-7-2).
Check bits; interlock check and synchrocheck check, are only valid for LN types
based upon CSWI class.
Verification of Originator Category is supported, see also PIXIT.
