Page 72 This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the B90 COM terminal (#3); others function cor- rectly only if the common wire is connected to the B90 COM terminal, but insulated from the shield.
Page 73: Irig-B
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the B90 operates an internal oscillator with 1 µs resolution and accuracy.
Page 74 UR-series relays can be synchronized. The IRIG-B repeater has a bypass function to maintain the time signal even when a relay in the series is powered down.

Page 126 When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond- ing connection password. If the connection is to the back of the B90, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.

Page 128 INVALID ATTEMPTS BEFORE LOCKOUT The B90 provides a means to raise an alarm upon failed password entry. Should password verification fail while accessing a password-protected level of the relay (either settings or commands), the FlexLogic operand is UNAUTHORIZED ACCESS asserted.
Page 129 If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeout is restarted. The status of this timer is updated every 5 seconds. GE Multilin B90 Low Impedance Bus Differential System...
Page 130: 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 B90 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 131: 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 B90 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 132: Communications
0 ms The B90 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 133 This allows the EnerVista UR Setup software to be used on the port. The UR operates as a Modbus slave device only. When using Modbus protocol on the RS232 port, the B90 responds regardless of the pro- MODBUS SLAVE ADDRESS grammed.

Page 135 TIMEOUT: 120 s The B90 supports the Distributed Network Protocol (DNP) version 3.0. The B90 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the B90 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the B90 at one time.
Page 136 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the B90 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 137 When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays, check the “DNP Points Lists” B90 web page to view the points lists. This page can be viewed with a web browser by enter- ing the B90 IP address to access the B90 “Main Menu”, then by selecting the “Device Information Menu” > “DNP NOTE Points Lists”...

Page 139 The B90 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 B90 operates as an IEC 61850 server. The Remote inputs and outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 140 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 B90 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 141 DESTINATION MAC address; the least significant bit of the first byte must be set. In B90 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 B90) and setting the multicast bit.
Page 142 The B90 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.

Figure 9–2: BIASED OPERATING CHARACTERISTIC The higher slope used by the B90 acts as an actual percentage bias regardless of the value of the restraining signal.

Page 291: Enhanced Security
9.3 DIFFERENTIAL PRINCIPLE 9.3.3 ENHANCED SECURITY In order to enhance the performance of the B90, the differential characteristic is divided into two regions having diverse operating modes as shown in following diagram. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low- current external faults.
Page 292: Current Directional Protection
9.4.1 CURRENT DIRECTIONAL PROTECTION For better security, the B90 uses the current directional protection principle to dynamically supervise the main current differ- ential function. The directional principle is in effect permanently for low differential currents (Region 1 in Figure 9–3: Two Regions of Differential Characteristic) and is switched on dynamically for large differential currents (Region 2 in the same figure) by the saturation detector (see Section 9.5: Saturation Detector) upon detecting CT saturation.
Page 293 9.4 DIRECTIONAL PRINCIPLE The B90 implementation calculates the maximum angle for the considered currents and compares it against a fixed thresh- old of 90°. The flag indicating whether the directional protection principle is satisfied is available as the FlexLogic™ oper-...
Page 294: Ct Saturation Detection
9.5.1 CT SATURATION DETECTION The saturation detector of the B90 takes advantage of the fact that any CT operates correctly for a short period of time even under very large primary currents that would subsequently cause a very deep saturation. As a result of that, in the case of an external fault, the differential current stays very low during the initial period of linear operation of the CTs while the restraining signal develops rapidly.

Page 409: C.1.1 Introduction
The B90 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the B90 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the B90 to have an IP address to establish communications. These addresses are located in the ...
Page 410: C.1.3 File Transfer By Iec 61850
APPENDIX C C.1.3 FILE TRANSFER BY IEC 61850 The B90 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 411: C.2.1 Overview
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the B90 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 412: C.2.6 Mmxn: Analog Measured Values
C.2.6 MMXN: ANALOG MEASURED VALUES A limited number of measured analog values are available through the MMXN logical nodes. Each MMXN logical node provides data from a B90 current and voltage terminal. There is one MMXN available for each configurable terminal (programmed in the ...

Page 414: C.3.1 Buffered And Unbuffered Reporting
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the B90. 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 415: C.3.6 Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the B90 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 B90. This frees up the con- nection to be used by other clients.
Page 416: C.4.1 Overview
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 B90 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 417 The B90 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 418: C.4.5 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 B90 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 419: C.4.6 Gsse Id And Goose Id Settings
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the B90 is configured to use an automated multicast MAC scheme. If the B90 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 420: C.5.1 Overview
An ICD file is generated for the B90 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 421: C.5.2 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 B90 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 422: C.5.3 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 >...
Page 423 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 B90 Low Impedance Bus Differential System C-15...

Page 426: C.5.4 Creating An Icd File With Enervista Ur Setup
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 B90 settings file is typically much quicker than create an ICD file directly from the relay.
Page 427 Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals.

Page 429: C.5.6 Importing An Scd File With Enervista Ur Setup
Figure C–9: SCD FILE STRUCTURE, IED NODE C.5.6 IMPORTING AN SCD FILE WITH ENERVISTA UR SETUP The following procedure describes how to update the B90 with the new configuration from an SCD file with the EnerVista UR Setup software. Right-click anywhere in the files panel and select the Import Contents From SCD File item.
Page 430 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.
