When a settings file is transferred to a T60 device, the date, time, and serial number of the T60 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor- mation can be compared with the T60 actual values at any later date to determine if security has been compromised.
Page 129 With respect to the above diagram, the traceability feature is used as follows. The transfer date of a setting file written to a T60 is logged in the relay and can be viewed via EnerVista UR Setup or the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.

SERIAL PORTS The T60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM2 port be used for either RS485 or RRTD communications.
Page 174 ETHERNET NETWORK TOPOLOGY The T60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND oper- ation performed between their respective IP address and mask produces a different result.

Page 186 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the T60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer- tain ranges in DNP masters.

That is, the DNP master can operate a single point for both trip and close, or raise and lower, operations. The T60 can be configured to sup- port paired control points, with each paired control point operating two virtual inputs.
Page 188 The T60 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over Ethernet. The T60 operates as an IEC 61850 server. The Remote Inputs and Out- puts section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 189 IEC 61850 GSSE application ID name string sent as part of each GSSE message. This GSSE ID string identifies the GSSE message to the receiving device. In T60 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 190 DESTINATION MAC address; the least significant bit of the first byte must be set. In T60 releases previous to 5.0x, the destination Ethernet MAC address was determined automatically by taking the sending MAC address (that is, the unique, local MAC address of the T60) and setting the multicast bit.
Page 191 The T60 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.

All CTs at the transformer are connected wye (polarity markings pointing away from the transformer). User-entered settings in the relay characterizing the transformer being protected and allow the relay to automatically perform all necessary magnitude, phase angle, and zero-sequence compensation.
Page 257 The reason the source phase sequence must be stated when describing the winding phase relationships is that these rela- tionships change when the phase sequence changes. The example shown below shows why this happens, using a trans- former described in IEC nomenclature as a type “Yd1” or in GE Multilin nomenclature as a “Y/d30.” 828716A1.CDR Figure 5–27: EXAMPLE TRANSFORMER...
Page 258 Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed.
Page 259 5 SETTINGS 5.4 SYSTEM SETUP The T60 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of one winding before the calculation of differential and restraint quantities. The reference winding (w ) is the winding to which all currents are referred.
Page 260 The T60 performs this phase angle compensation and zero sequence removal automatically, based on the settings entered for the transformer. All CTs are connected Wye (polarity markings pointing away from the transformer). All currents are phase and zero sequence compensated internally before the calculation of differential and restraint quantities.

Figure 5–57: UR ARCHITECTURE OVERVIEW The states of all digital signals used in the T60 are represented by flags (or FlexLogic operands, which are described later in this section). A digital “1” is represented by a 'set' flag. Any external contact change-of-state can be used to block an ele- ment from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output.
Page 304 Some types of operands are present in the relay in multiple instances; e.g. contact and remote inputs. These types of oper- ands are grouped together (for presentation purposes only) on the faceplate display. The characteristics of the different types of operands are listed in the table below.

LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser- vices in IEC 61850-8-1. The T60 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the T60 to have an IP address to establish communications. These addresses are located in the ...
Page 718: File Transfer By Iec 61850
APPENDIX C C.1.3 FILE TRANSFER BY IEC 61850 The T60 supports file transfer by IEC 61850. The approach is as follows, using the SISCO AX-S4 61850 client software as an example. In the AX-S4 61850 Explorer window, click the Tools menu and access the SISCO File Transfer Utility.
Page 719: Server Data Organization
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the T60 to provide access to as many 128 digital status points and associated time- stamps and quality flags. The data content must be configured before the data can be used. GGIO1 provides digital status points for access by clients.
Page 720: Mmxu: Analog Measured Values
A limited number of measured analog values are available through the MMXU logical nodes. Each MMXU logical node provides data from a T60 current and voltage source. There is one MMXU available for each con- figurable source (programmed in the ...
Page 721 The protection elements listed above contain start (pickup) and operate flags. For example, the start flag for PIOC1 is PIOC1.ST.Str.general. The operate flag for PIOC1 is PIOC1.ST.Op.general. For the T60 protection elements, these flags take their values from the pickup and operate FlexLogic operands for the corresponding element.
Page 722: Server Features And Configuration
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the T60. This name is composed of two parts: the IED name setting and the logical device instance. The complete logical device name is the combination of the two character strings programmed in the settings.
Page 723: Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the T60 to detect ‘dead’ connections. If there is no data traffic on a TCP connection for greater than two minutes, the connection will be aborted by the T60. This frees up the con- nection to be used by other clients.
Page 724: Generic Substation Event Services: Gsse And Goose
MAC address for GSSE messages. If GSSE DESTINATION MAC ADDRESS a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00), the T60 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 725 The T60 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.
Page 726 REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The T60 must be rebooted (control power removed and re-applied) before these settings take effect. The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value in the sending device.
Page 727: Ethernet Mac Address For Gsse/Goose
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the T60 is configured to use an automated multicast MAC scheme. If the T60 destination MAC address setting is not a valid multicast address (that is, the least significant bit of the first byte is not set), the address used as the destina- tion MAC will be the same as the local MAC address, but with the multicast bit set.
Page 728: Iec 61850 Implementation Via Enervista Ur Setup
An ICD file is generated for the T60 by the EnerVista UR Setup software that describe the capabilities of the IED. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven- dors) for system configuration.
Page 729: Configuring Iec 61850 Settings
Transmission GOOSE dataset may be added or deleted, or prefixes of some logical nodes may be changed. While all new configurations will be mapped to the T60 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 730: About Icd Files
Although configurable transmission GOOSE can also be created and altered by some third-party system con- figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictly within EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com- munications >...

The EnerVista UR Setup will prompt to save the file. Select the file path and enter the name for the ICD file, then click OK to generate the file. The time to create an ICD file from the offline T60 settings file is typically much quicker than create an ICD file directly from the relay.
Page 735 Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals.

Right-click anywhere in the files panel and select the Import Contents From SCD File item.
Page 738 The software will open the SCD file and then prompt the user to save a UR-series settings file. Select a location and name for the URS (UR-series relay settings) file. If there is more than one GE Multilin IED defined in the SCD file, the software prompt the user to save a UR-series set- tings file for each IED.
