5-84 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5As mentioned in the preceding GOOSE and Reports sections, the members whose values are communicated by theseservices are itemized in an ordered list known as a data set. Each UR with the IEC 61850 option has 18 data sets (six fastand 12 slow). Each data set can contain as many as 64 members. Any data set can be used simultaneously by any numberof TxGOOSE elements and/or by any number of Configurable Report elements. UR Setup software can configure anyFlexLogic operands and any FlexAnalog operands as members.Figure 5-34: IEC 61850 DataSetsUR Setup software requires data set members to be IEC 61850 data objects or data attributes with Functional ConstraintST or MX. Certain FlexLogic and FlexAnalog operands have factory-assigned data attributes as tabulated in the UR FamilyCommunications Guide. All FlexLogic and FlexAnalog operands can be user-assigned to GGIO1 or GGIO4 data attributes,so that operands without factory-assigned data attributes can still have their values published. See the GGIO1 and GGIO4sections later for details.Datasets used by TxGOOSE1, TxGOOSE2, and/or by reports also provide a chatter suppression service for their Booleanmembers. Oscillation in a value, also known as chatter, can be caused by errors in logic programming, inadequatehysteresis (deadband) on a threshold, or a failed station component. Chatter can flood a communications network withGOOSE messages, degrading response time for all users. If chatter is detected in a Boolean member, TxGOOSE suspendsGOOSE event message triggering and report message triggering from that member for as long as the condition exists, andfor a minimum period of one second. While sending is suspended, a self-test message identifying the specific data itemdetected as oscillating is activated.For a summary of the panels in which the data sets are used, the path is Settings > Product Setup > Communications >IEC 61850 > DataSets > Summary.For the settings, navigate to Settings > Product Setup > Communications > IEC 61850 > DataSets > TT6DataSet1 for thefirst data set.Copy and paste functions are available when right-clicking a DataSet. They allow the target dataset to be configuredbased on its order code. If some dataset items are not supported, they are not pasted, and a warning message shows a listof dataset items that were not supported and not pasted. The DataSet name is not copied or pasted. In short, use thisfeature to copy a DataSet Member setting and paste it into another Member setting, a text file, or Word, as examples.
