5-16 F60 Feeder Management Relay GE Multilin5.2 PRODUCT SETUP 5 SETTINGS5ited response without receiving confirmation from the master; a value of “255” allows infinite re-tries. The DNP UNSOLRESPONSE DEST ADDRESS is the DNP address to which all unsolicited responses are sent. The IP address to which unsolic-ited responses are sent is determined by the F60 from the current TCP connection or the most recent UDP message.The DNP SCALE FACTOR settings are numbers used to scale Analog Input point values. These settings group the F60 Ana-log Input data into types: current, voltage, power, energy, and other. Each setting represents the scale factor for all AnalogInput points of that type. For example, if the DNP VOLTAGE SCALE FACTOR setting is set to a value of 1000, all DNP AnalogInput points that are voltages will be returned with values 1000 times smaller (e.g. a value of 72000 V on the F60 will bereturned as 72). These settings are useful when analog input values must be adjusted to fit within certain ranges in DNPmasters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (i.e. the value will be 10 times larger).The DNP DEFAULT DEADBAND settings determine when to trigger unsolicited responses containing Analog Input data. Thesesettings group the F60 Analog Input data into types: current, voltage, power, energy, and other. Each setting represents thedefault deadband value for all Analog Input points of that type. For example, to trigger unsolicited responses from the F60when any current values change by 15 A, the DNP CURRENT DEFAULT DEADBAND setting should be set to “15”. Note thatthese settings are the deadband default values. DNP Object 34 points can be used to change deadband values, from thedefault, for each individual DNP Analog Input point. Whenever power is removed and re-applied to the F60, the defaultdeadbands will be in effect.The DNP TIME SYNC IIN PERIOD setting determines how often the Need Time Internal Indication (IIN) bit is set by the F60.Changing this time allows the DNP master to send time synchronization commands more or less often, as required.The DNP MESSAGE FRAGMENT SIZE setting determines the size, in bytes, at which message fragmentation occurs. Largefragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to benecessary which can provide for more robust data transfer over noisy communication channels.When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays,check the “DNP Points Lists” F60 web page to view the points lists. This page can be viewed with a webbrowser by entering the F60 IP address to access the F60 “Main Menu”, then by selecting the “Device Infor-mation Menu” > “DNP Points Lists” menu item.The DNP OBJECT N DEFAULT VARIATION settings allow the user to select the DNP default variation number for object types 1,2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation response when variation 0 is requested and/or inclass 0, 1, 2, or 3 scans. Refer to the DNP Implementation section in Appendix E for additional details.The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a singlephysical or virtual control point in an IED. In the F60 relay, DNP binary outputs are mapped to virtual inputs. However, somelegacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to supportthe concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNPmaster can operate a single point for both trip and close, or raise and lower, operations. The F60 can be configured to sup-port paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED CONTROLPOINTS setting allows configuration of from 0 to 16 binary output paired controls. Points not configured as paired operate ona one-to-one basis.The DNP ADDRESS setting is the DNP slave address. This number identifies the F60 on a DNP communications link. EachDNP slave should be assigned a unique address.f) DNP / IEC 60870-5-104 POINT LISTSPATH: SETTINGS Ö PRODUCT SETUP ÖØ COMMUNICATIONS ÖØ DNP / IEC104 POINT LISTSThe binary and analog inputs points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104 protocol, canconfigured to a maximum of 256 points. The value for each point is user-programmable and can be configured by assigningFlexLogic™ operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
