Table 3-8: Typical Quality data attribute values in UR devices
Many of the UR series device elements have multiple instances, and in many cases the number of instances depends on
the product or the device's order code. Also, many UR elements have operands and/or settings that are repetitive, such as
for every phase, or for every step. Again for brevity, in the following information model outline a template representing
multiple logical nodes or multiple data objects is often used. These templates are identified with a Greek or punctuation
character, such as
γ or #, in the logical node/data object name. In a UR device, the template is instantiated multiple times
with the punctuation or Greek character replaced with the appropriate instance number or instance identifier.
The R/W/C column in the following tables is coded as follows:
•
R — Value of the data object or data attribute is readable via MMS services
• W — Value of the data object or data attribute is writable via MMS services
• C — Value of the data object or data attribute is configurable via SCL file download
• Ctrl — The data object can be controlled via MMS services
The logical nodes implemented in UR devices since version 7.30 are sorted into six logical devices. The table outlines the six
logical devices and the general rules for the fixed assignment of logical nodes to them. Each logical device has a section in
this chapter that defines the logical nodes implemented for that logical device.
Table 3-9: Logical devices
3.5.1 Master (root) logical device
The Master logical device contains communications-related logical nodes, including GOOSE, reports, log, and virtual inputs.
d This textual description is in every logical node. When in a NamPlt data object, the description refers to the logical
device, otherwise it describes the data object it is in. These data attributes are readable via MMS services and
reconfigurable via SCL file download.
dataNs The data name space is included in data objects that extend those specified by the logical node class in the standard.
Where the extended data object is defined in IEC 61850 7 4, its value is "IEC 61850-7-4:2007B". Otherwise, it has the
value "GE Multilin Namespace:2013A" and is defined in the GE Namespace subsection of this section. These data
attributes are readable via MMS services.
