  • Page 3: Introduction

    Introduction vacon • 3 INTRODUCTION Vacon NX frequency converters can be connected to Ethernet using an Ethernet fieldbus board OPTCI. The OPTCI can be installed in the card slots D or E. Every appliance connected to an Ethernet network has two identifiers; a MAC address and an IP address.

    Installation vacon • 7 INSTALLATION Installing the Ethernet Option Board in a Vacon NX Unit MAKE SURE THAT THE FREQUENCY CONVERTER IS SWITCHED OFF BEFORE AN OPTION OR FIELDBUS BOARD IS CHANGED OR ADDED! NOTE Vacon NX frequency converter. Remove the cable cover.
  • Page 8 8 • vacon installation Install EtherNet/IP option board in slot D or E on the control board of the frequency converter. Make sure that the grounding plate (see below) fits tightly in the clamp. Make a sufficiently wide opening for your cable by cutting the grid as wide as necessary.

  • Page 9: Ncdrive

    NOTE! NCLoad does not work via Ethernet. See NCDrive help for further information. IP Tool NCIPConfig To begin using the Vacon EtherNet/IP board, you need to set an IP address. The factory default IP address is 192.168.0.10. Before connecting the board to the network, its IP addresses must be set according to the network.
  • Page 10 3.3.1 Update OPTCI Option Board program with the NCIPConfig Tool In some cases it may be necessary to update the option board's firmware. Differing from other Vacon option boards, the EtherNet/IP option board's firmware is updated with the NCIPConfig tool.
  • Page 11 The Safe Mode triggers a fault code (F54). The Board slot error F54 may also appear due to a faulty board, a temporary malfunction of the board or disturbance in the environment. 24-hour support +358 (0)40 837 1150 • Email: vacon@vacon.com...
  • Page 12 12 • vacon installation Configure Option board parameters These features are available from NCIPConfig tool version 1.6. In the tree-view, expand the folders until you reach the board parameters. Slowly double-click the parameter ( Comm. Time-out in figure below) and enter new value. New parameter values are automatically sent to the option board after the modification is complete.

  • Page 13: Commissioning

    Modbus/tcp vacon • 13 COMMISSIONING The Vacon EtherNet/IP board is commissioned with the control keypad by giving values to IP Tool appropriate parameters in menu M7 (or with NCIPConfig tool, read chapter NCIPConfig ). Keypad commissioning is only possible with NXP- and NXS-type frequency converters, not possible with NXL-type frequency converters.
  • Page 14 14 • vacon Commissioning NOTE! If fieldbus cable is broken from Ethernet board end, fieldbus error is generated immediately. All Ethernet parameters are saved to the Ethernet board (not to the control board). If new Ethernet board is changed to control board you must configure the new Ethernet board. Option board parameters are possible to save to the keypad, with NCIPConfig tool or with NCDrive.

  • Page 16: Modbus/Tcp Vs. Modbus Rtu

    16 • vacon Commissioning MODBUS/TCP vs. MODBUS RTU Compared to the MODBUS RTU protocol, the MODBUS/TCP differs mostly in error checking and slave addresses. As the TCP already includes an efficient error checking function, the MODBUS/TCP protocol does not include a separate CRC field. In addition to the error checking functionality, the TCP is responsible for resending packets and for splitting long messages so that they fit the TCP frames.

  • Page 18: Input Discrete

    Both the 'Coil register' and the 'Input discrete register' contain binary data. However, the difference between the two registers is that the Input register's data can only be read. The Vacon Ethernet board's MODBUS/TCP implementation uses the following Input discrete addresses.
