compare the new value with the minVal and maxVal attributes, when applicable
(this depends on the data type and if the minVal and maxVal are mapped). So if the
minVal and maxVal are not mapped, all values in the range of the data type will be
accepted. If the written value is outside the range, Object-Value-Invalid will be
returned to the client.
Note that the actual number of used setting groups is defined by the
parameter MaxNoSetGRP in the function SETGRPS, which is
configured in ECT in PCM600. But six setting groups is the
maximum and it cannot be exceeded.
Generic object oriented substation event (GOOSE)
The structured GOOSE is supported. This means that the data sets can be defined
with FCDA as well as explicit attributes.
The supported data types to be published and received over GOOSE are binary
values, double point values, integer values and measured values, together with their
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
(like in the case of MMXU functions), then one can add that value directly to the
data set. If the value is not event-handled, (like in the case of Synchrocheck
function), 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.
Example of functions that have event-handled measured values (can be added
directly to the data set).
• CVMMXN - Measurements
• CMMXU - Phase current measurement
• VMMXU - Phase-phase voltage measurement
• CMSQI - Current sequence component measurement
