  • Page 14: Software Architecture

    Employing OOD/OOP in the software architecture of the D60 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.

  • Page 16: Configuring The D60 For Software Access

    OVERVIEW The user can connect remotely to the D60 through the rear RS485 port or the rear Ethernet port with a computer running the EnerVista UR Setup software. The D60 can also be accessed locally with a laptop computer through the front panel RS232 port or the rear Ethernet port using the Quick Connect feature.
  • Page 17 An Ethernet module must be specified at the time of ordering. • To configure the D60 for local access with a laptop through either the front RS232 port or rear Ethernet port, see the Using the Quick Connect Feature section.
  • Page 18 1 GETTING STARTED 10. Click the Read Order Code button to connect to the D60 device and upload the order code. If a communications error occurs, ensure that the EnerVista UR Setup serial communications values entered in the previous step correspond to the relay setting values.
  • Page 19: Using The Quick Connect Feature

    USING QUICK CONNECT VIA THE REAR ETHERNET PORTS To use the Quick Connect feature to access the D60 from a computer through Ethernet, first assign an IP address to the relay from the front panel keyboard. Press the MENU key until the SETTINGS menu displays.
  • Page 20 Now, assign the computer an IP address compatible with the relay’s IP address. From the Windows desktop, right-click the My Network Places icon and select Properties to open the network con- nections window. Right-click the Local Area Connection icon and select Properties. 1-10 D60 Line Distance Protection System GE Multilin...
  • Page 21 Select the Internet Protocol (TCP/IP) item from the list, and click the Properties button. Click the “Use the following IP address” box. Enter an IP address with the first three numbers the same as the IP address of the D60 relay and the last number dif- ferent (in this example, 1.1.1.2).

If this computer is used to connect to the Internet, re-enable any proxy server settings after the computer has been discon- nected from the D60 relay. AUTOMATIC DISCOVERY OF ETHERNET DEVICES The EnerVista UR Setup software can automatically discover and communicate to all UR-series IEDs located on an Ether- net network.
  • Page 25: Connecting To The D60 Relay

    The EnerVista UR Setup software has several quick action buttons to provide instant access to several functions that are often performed when using D60 relays. From the online window, users can select the relay to interrogate from a pull-down window, then click the button for the action they want to perform. The following quick action functions are available: •...
  • Page 26: Ur Hardware

    This device (catalog number F485) connects to the computer using a straight-through serial cable. A shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the D60 rear communications port. The converter terminals (+, –, GND) are connected to the D60 communication module (+, –, COM) terminals. See the CPU communica- tions ports section in chapter 3 for details.

    As such, no further functional tests are required. The D60 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7). However, it is recommended that D60 maintenance be scheduled with other system maintenance.

  • Page 31: Product Description

    D60 phase distance zones can be configured to work with voltages and currents fed from VTs and CTs located indepen- dently from one another on either side of a three-phase power transformer. The relay compensates accordingly to preserve reach and correct target information regardless of the location and type of fault.

The D60 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the D60 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the D60 at one time.

    Figure 5–51: UR ARCHITECTURE OVERVIEW The states of all digital signals used in the D60 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.
