    INSTALLATION CONFIGURATION CABLE The PC connector is indicated as B in Figure 2-1: D485 electrical connections on page 2–2. This connector is used to connect the D485 to a PC using the configuration cable for configuration and monitoring purposes. A configuration cable can be purchased from GE Multilin. The wiring for the configuration cable is shown below.

  • Page 14: Modbus Connector

    The Modbus connector is indicated as C in Figure 2-1: D485 electrical connections on page 2–2. This connector is used to connect the D485 to the serial network. Based on the configuration selected in the EnerVista P485/D485 Setup software, the corresponding signals are activated.

  • Page 16: Configuration Switches

    Normally, these switches are covered by a plastic hatch. Note that the node address can not be changed during runtime, i.e. the D485 requires a reset for any changes to have effect. Recycle the power supply to reset the module.

  • Page 17: Devicenet Installation Procedure

    Baud rate: The DeviceNet network baud rate should match the D485 baud rate setting. DEVICENET NETWORK If the D485 is the last node on a DeviceNet network, it is necessary to use a DeviceNet TERMINATION network termination resistor of 120 ohms between the CAN L and CAN H terminals.

    BUFFER STRUCTURE data; input data, output data and general data. • Input data: This is data that should be sent to the fieldbus. The D485 can handle up to 512 bytes of input data. • Output data: this is data recieved from the fieldbus. The D485 can handle up to 512 bytes of output data.

  • Page 21: I/O Data Vs. Explicit Data

    The amount of data that should be treated as I/O data is determined by the ‘I/O Sizes’ parameter in the EnerVista P485/D485 Setup software. The remainder will be treated as explicit data. By default (that is, when using ‘automatic’ I/O sizes), all data is treated as I/O data.

  • Page 23: Protocol Configuration

    Protocol configuration DESCRIPTION In order to be able to communicate on the Modbus sub-network, the D485 must be supplied with a description of the required sub-net protocol. To accomplish this, the EnerVista P485/D485 Setup software features a flexible protocol-programming system, allowing the D485 to interpret and exchange data with almost any serial device on the Modbus sub-network.

  • Page 36: Sub-Network Properties

    RS232 is a point-to-point communication standard; that is, it is only possible to have one sub-network node (Modbus device) connected to the D485 converter when using RS232. RS232 supports a maximum cable length of 15 meters and is full duplex. It uses two signal lines (Rx and Tx) and the signal is measured relative to ground.

  • Page 37: Device Types

    In most GE Multilin relay and meter documentation, Modbus addresses are indicated in hexadecimal form. For the Modicon format used for the D485, convert the hex address to decimal, add 1, then append a prefix of 1, 2, 3, or 4, depending on the type of register. For...

  • Page 41: Configuration Main Window

    SOFTWARE OVERVIEW If the Sub-net Overview button is pressed, a new window will appears that graphically displays how the data is mapped to the internal memory of the D485. Configuration main window DESCRIPTION The main window is shown below. It is composed of the navigation window, parameter window, information window, and configuration line indicator.

  • Page 42: Navigation Window

    SOFTWARE OVERVIEW NAVIGATION WINDOW The navigation window in EnerVista P485/D485 Setup is the main tool for selecting the different levels of the configuration. There are three main levels in the navigation window, namely fieldbus, D485, and Modbus network. Menu entries preceded by a plus symbol (+) contain more configuration parameters or sub-menus.

  • Page 43: Options Window

    During start-up, the fieldbus interface is initialized to fit the configuration created in the EnerVista P485/D485 Setup software. Since EnerVista P485/D485 Setup supports both the P485 and D485 converters, the user must verify that the 'Fieldbus' parameter indicates the correct converter. Additionally, it is possible for advanced users to customize the network interface inside the converter to meet specific application demands (see Advanced fieldbus configuration on page 8–5 for details).

  • Page 44: P485/D485 Configuration

    SOFTWARE OVERVIEW P485/D485 configuration PARAMETER WINDOW By selecting 'P485/D485 ' in the Navigation window, basic configuration options for the sub-net will appear in the Parameter window. Figure 4-6: P485/D485 configuration • Physical interface: Currently, the D485 supports only a serial interface. The communication settings for the selected interface are available under 'Modbus Network (see Serial interface settings on page 4–13 for details).

  • Page 45: Modbus Network Configuration

    When controlling a Modbus sub-network with the D485 it is important to understand functions during starting up. If the D485 starts scanning nodes on the sub-network, before data is received from the fieldbus control system (fieldbus master), values of ‘00’ may be transmitted to the nodes before data is updated the first time from the fieldbus.
  • Page 46 SOFTWARE OVERVIEW 4–14 D485 MODBUS TO DEVICENET CONVERTER – USER GUIDE...

  • Page 47: Communication Model

    Introduction DESCRIPTION In master mode, the D485 is configured to run as a master on the Modbus sub-network, using a scan-list for communication with the Modbus slave devices. The scan-list is created using EnerVista P485/D485 Setup and can consist of multiple nodes with multiple transactions.

  • Page 48: Scan List

    According to the Modbus specification, the message delimiter has a default setting of 3.5 characters.If this value is set to “0”, the D485 will use the Modbus standard 3.5 character message delimiter. The time in milliseconds is then dependent on the selected baud rate, but this is all handled by the D485.

  • Page 49: Nodes

    COMMUNICATION MODEL Nodes DESCRIPTION A node in the EnerVista P485/D485 Setup software represents a device on the Modbus sub-network. In it’s simplest form, a Node contains of a single transaction, that consists of a Query and a Response. NODE PARAMETERS To gain access to these parameters, select the desired node in the navigation window.

  • Page 50: Query Parameters

    D485 should wait after the broadcast was sent until the next command in the scan-list will be sent. This time should be selected such that all slave-devices connected to the D485 have time to finish the handling of the broadcast.

  • Page 51: Response Parameters

    Trigger byte: This parameter disables and enables the trigger functionality for the response. If the “trigger byte” is enabled then the D485 will increase the byte at the “trigger byte address” by one when the D485 receives new data from the Modbus network.
