Page 29: Commissioning
The G60 requires a minimum amount of maintenance when it is commissioned into service. Since the G60 is a micropro- cessor-based relay, its characteristics do not change over time. As such, no further functional tests are required. Furthermore, the G60 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-Test section in Chapter 7 for details).

The terminal configuration for contact inputs is different for the two applications. The digital inputs are grouped with a common return. The G60 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.

BACKGROUND The G60 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 G60 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 107: 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 G60 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 108 The G60 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 109: 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 G60 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 110: Communications
0 ms The G60 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 111 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each G60 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 113 TIMEOUT: 120 s The G60 supports the Distributed Network Protocol (DNP) version 3.0. The G60 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the G60 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the G60 at one time.
Page 114 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the G60 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 116 The G60 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 G60 operates as an IEC 61850 server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 117 DESTINATION MAC address; the least significant bit of the first byte must be set. In G60 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 G60) and setting the multicast bit.
Page 118 DATASET ITEMS The configurable GOOSE settings allow the G60 to be configured to transmit a number of different datasets within IEC 61850 GOOSE messages. Up to eight different configurable datasets can be configured and transmitted. This is useful for intercommunication between G60 IEDs and devices from other manufacturers that support IEC 61850.
Page 119 CPU resources. When server scanning is disabled, there will be not updated to the IEC 61850 logical node sta- tus values in the G60. Clients will still be able to connect to the server (G60 relay), but most data values will not be updated.
Page 120 (_) 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 G60 is restarted. The main menu for the IEC 61850 MMXU deadbands is shown below.
Page 121 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 G60 virtual inputs.
Page 122 MESSAGE IntgPd: Changes to the report configuration will not take effect until the G60 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 123 NUMBER: The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the G60 over a network. The G60 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the G60 contains a list and description of all available files (event records, oscillography, etc.).
Page 124 G60 clock is closely synchronized with the SNTP/NTP server. It may take up to two minutes for the G60 to signal an SNTP self-test error if the server is offline.
Page 125 MESSAGE (Modbus register address range) Fast exchanges (50 to 1000 ms) are generally used in control schemes. The G60 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:...

EXCH 1 DATA ITEM 1 to 20/50: These settings specify the data items that are part of this EGD exchange. Almost any data from the G60 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus register address for the data item in decimal format.
Page 127: Real Time Clock
SNTP, the offset is used to determine the local time for the G60 clock, since SNTP provides UTC time. The daylight savings time (DST) settings can be used to allow the G60 clock can follow the DST rules of the local time zone.

Page 429: Iec 61850 Communications
The G60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the G60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the G60 to have an IP address to establish communications. These addresses are located in the menu.
Page 430: Server Data Organization
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the G60 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 G60 relay will contain a subset of protec- tion elements from this list. • PDIF: transformer instantaneous differential, transformer percent differential •...
Page 432 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 G60 protection elements, these flags take their values from the pickup and operate FlexLogic™ operands for the corresponding element.
Page 433: 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 G60. 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 434: Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the G60 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 G60. This frees up the con- nection to be used by other clients.
Page 435: Overview
(for example, 00 00 00 00 00 00), messages always contain the same number of DNA and the G60 will use the source Ethernet MAC address as the UserSt bit pairs. Depending the on the configuration, only destination, with the multicast bit set.
Page 436 This example shows how to configure the transmission and The G60 must be rebooted (control power removed and re- reception of three IEC 61850 data items: a single point sta- applied) before these settings take effect.
Page 437: Ethernet Mac Address For Gsse/Goose
REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic™ equations or other settings. The G60 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 438: Iec 61850 Implementation Via Enervista Ur Setup
An ICD file is generated for the G60 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 439: 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 G60 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 440: 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 G60 settings file is typically much quicker than create an ICD file directly from the relay.
