The terminal configuration for contact inputs is different for the two applications. The digital inputs are grouped with a common return. The T60 has two versions of grouping: four inputs per common return and two inputs per common return. When a digital input/output module is ordered, four inputs per common is used. The four inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs sharing one common.

Page 101: Introduction To Ac Sources
BACKGROUND The T60 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail- ure element.

FlexLogic™ operand will be set to “On” and REMOTE ACCESS DENIED the T60 will not allow Settings or Command access via the any external communications interface for the next ten minutes. FlexLogic™ operand will be set to “Off” after the expiration of the ten-minute timeout.
Page 105: Display Properties
Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The T60 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 106 The T60 applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below the cut-off level, it is substituted with zero.
Page 107: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the T60 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 108: Communications
0 ms The T60 is equipped with up to three independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet or RS485 port.
Page 109 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each T60 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur.

Page 111 TIMEOUT: 120 s The T60 supports the Distributed Network Protocol (DNP) version 3.0. The T60 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the T60 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the T60 at one time.
Page 112 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.

Page 114 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 and TP4/CLNP (OSI) over ethernet. The T60 operates as an IEC 61850 server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 115 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 116 For intercommunication between T60 IEDs, the fixed (DNA/UserSt) dataset can be used. The DNA/UserSt dataset contains the same DNA and UserSt bit pairs that are included in GSSE messages. All GOOSE messages transmitted by the T60 (DNA/UserSt dataset and configurable datasets) use the IEC 61850 GOOSE messaging services (for example, VLAN sup- port).
Page 117 CPU resources. When server scanning is disabled, there will be not updated to the IEC 61850 logical node sta- tus values in the T60. Clients will still be able to connect to the server (T60 relay), but most data values will not be updated.
Page 118 (_) character, and the first character in the prefix must be a letter. This conforms to the IEC 61850 standard. Changes to the logical node prefixes will not take effect until the T60 is restarted. The main menu for the IEC 61850 MMXU deadbands is shown below.
Page 119 The GGIO2 control configuration settings are used to set the control model for each input. The available choices are “0” (status only), “1” (direct control), and “2” (SBO with normal security). The GGIO2 control points are used to control the T60 virtual inputs.
Page 120 MESSAGE IntgPd: Changes to the report configuration will not take effect until the T60 is restarted. Since GSSE/GOOSE messages are multicast Ethernet by specification, they will not usually be forwarded by net- work routers. However, GOOSE messages may be fowarded by routers if the router has been configured for VLAN NOTE functionality.
Page 121 NUMBER: The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the T60 over a network. The T60 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the T60 contains a list and description of all available files (event records, oscillography, etc.).
Page 122 T60 clock is closely synchronized with the SNTP/NTP server. It may take up to two minutes for the T60 to signal an SNTP self-test error if the server is offline.
Page 123 MESSAGE (Modbus register address range) Fast exchanges (50 to 1000 ms) are generally used in control schemes. The T60 has one fast exchange (Exchange 1) and two slow exchanges (Exchanges 2 and 3). The settings menu for the slow EGD exchanges is shown below:...

Page 157 CTs and tapped relay windings with some combination of CT connections. The T60 simplifies these configuration issues. 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 158 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.” 5-62...
Page 159 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 160 CTs or tapped relay windings were used to minimize this error. 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.
Page 161 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.

The T60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the T60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the T60 to have an IP address to establish communications. These addresses are located in the menu.
Page 422: 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.

• MMXU1.ST.PF.phsC: phase C power factor C.2.6 PROTECTION AND OTHER LOGICAL NODES The following list describes the protection elements for all UR-series relays. The T60 relay will contain a subset of protec- tion elements from this list. • PDIF: transformer instantaneous differential, transformer percent differential •...
Page 424 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 425: 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 426: 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.

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.

The T60 must be rebooted (control power removed and re-applied) before these settings take effect. The following procedure illustrates the reception configuration.

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 430: Overview
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 431: 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 432: 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 >...
