Page 14
The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any result- ing task execution is priority interrupt-driven. Figure 1–3: UR-SERIES SCAN OPERATION G60 Generator Protection System GE Multilin...
Employing OOD/OOP in the software architecture of the G60 achieves the same features as the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various functional classes.

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.
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-programma- ble 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.
SERIAL PORTS The G60 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 188
ETHERNET NETWORK TOPOLOGY The G60 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.

The serial communication ports utilize the Modbus protocol, unless the port is configured for DNP or IEC 60870-5-104 operation. This allows the EnerVista UR Setup software to be used on the port. The UR operates as a Modbus slave device only. GE Multilin G60 Generator Protection System 5-35...
Page 196
5.2 PRODUCT SETUP 5 SETTINGS When using Modbus protocol on the RS232 port, the G60 responds regardless of the pro- MODBUS SLAVE ADDRESS grammed. For the RS485 port, each device on the serial bus must have a unique slave address from 1 to 254. Address 0 and addresses from 248 and up are reserved by the Modbus protocol specification, and so their use here is not recom- mended.
Page 197
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 198
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 199
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays, check the “DNP Points Lists” G60 web page to view the points lists.

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. The G60 operates as an IEC 61850 server. The Remote inputs and outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.

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.

The G60 supports the IEC 60870-5-104 protocol. The G60 can be used as an IEC 60870-5-104 slave device connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the G60 maintains two sets of IEC 60870-5-104 data change buffers, no more than two masters should actively communicate with the G60 at one time.

LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser- vices in IEC 61850-8-1. The G60 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the G60 to have an IP address to establish communications. These addresses are located in the ...
APPENDIX C C.1.3 FILE TRANSFER BY IEC 61850 The G60 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.
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.
C.2.6 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 G60 current and voltage source. There is one MMXU available for each configurable source (programmed in the ...
Page 713
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.
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.
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.
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 G60 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 717
The G60 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 718
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.
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the G60 is configured to use an automated multicast MAC scheme. If the G60 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.
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.
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.
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 >...

Furthermore, it defines the capabilities of an IED in terms of communication services offered and, together with its LNType, instantiated data (DO) and its default or configuration values. There should be only one IED section in an ICD since it only describes one IED. GE Multilin G60 Generator Protection System C-15...

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.

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.
