ConfRev
The setVal data attribute is configured to an integer number from 0 through 2147483647. If the configured value is not
zero, only GOOSE messages with the configured value in the confRev field are accepted. If the configured value is zero,
any value in the confRev field is acceptable.
InRef
δδ
The intAddr data attribute is configured to either 1) a string that references the intermediate data attribute to which the
values received in the
δδ
th member of accepted GOOSE messages are saved, or 2) in case the
δδ
th member is not
subscribed to, "BOOLEAN", "FLOAT32", "INT32", "Dbpos", "Quality", or "Timestamp" according to the published type, or 3) ""
(empty string) in the case where
δδ
is greater than the number of members in the subscribed GOOSE.
The first InRef
δδ
wherein intAddr is the empty string marks the end of the GOOSE message. Any following InRef
δδ
are
ignored.
The format of LGOS#.InRef
δδ
.intAddr references is the referenced logical node name, a period, the data object name, a
period, and the data attribute name. The LGOS#.InRef
δδ
.intAddr data attributes are in the same IED and same LDevice
element as the referenced intermediate data attribute, so inclusion of the IED name and logical device instance name is
unnecessary. In UR 7.30 and later, the referenced logical node name is always "GGIO3". The data object name is either
Ind
ψ
for BOOLEAN members, AnIn
ψ
for FLOAT32 members, or PosInd
ψ
for double-point status members, where
ψ
is the
data object instance number. The data attribute name is either stVal for BOOLEAN or double point status members,
mag.f for FLOAT32 members, q for Quality members, or t for Timestamp members.
An example of LGOS#.InRef
δδ
.intAddr reference is as follows: GGIO3.Ind001.stVal
Note that LGOS#.InRef
δδ
data attribute setSrcRef is mandatory under the standard and is present. UR 7.30 and later
ignores any value in this data attribute on input, and may or may not preserve its value on output.
3.11.5 IID files
In UR-generated IID files, the LGOS configuration values outlined are identical to those in the most recently accepted CID
file.
UR Setup software offers the user a choice to generate an E3-2.0 model IID file or a G2 model IID file.
