  • Page 4: Introduction

    Introduction Introduction This user manual for the DeviceNet (FFD31C) Option describes how to install the DeviceNet option ® card in the frequency inverter and how to start up the MOVITRAC 31C on the DeviceNet fieldbus system. As well as explaining all settings on the fieldbus interface, this document also deals with the vari- ous DeviceNet connection variants in the form of brief startup examples.

  • Page 6: Installation

    Installation Installation Supported unit types The FFD31C option for the DeviceNet connection can be operated with all frequency inverters in the ® MOVITRAC 31C series. Installation of the option card Before you begin: • Take suitable measures to dissipate any electrical charge in your body before you touch the option card (discharge strap, conductive shoes, etc.).

  • Page 7: Shielding And Routing Of The Bus Cables

    Installation The DeviceNet option card is opto-decoupled on the driver side in accordance with the DeviceNet specification (Volume I, Chapter 9). This means the CAN bus driver must be powered with 24 V via the bus cable. The required cable is also described in the DeviceNet specification (Volume I, Appendix B). The connection must be made according to the color code specified in Table 1.

  • Page 8: Dip Switch Settings

    Installation DIP switch settings There are two DIP switch blocks of four DIP switches each on the FFD31C DeviceNet card. Two DIP switches are used for setting the baud rate and six for setting the MAC-ID (Media Access Control Identifier). The MAC-ID represents the node address of the FFD31C. Function Abbrev.

    Project Planning and Startup There is an EDS file MC31.eds and a bitmap file MC31.bmp for the FFD31C option card. These files must be installed using the DeviceNet Manager software. Select Utilities/Install EDS File from the menu. The program prompts you for the EDS file name and the bitmap file.
  • Page 14 Project Planning and Startup Configuration for three process data words The factory setting of the process data configuration is process data length = 3. The setting can be altered using the DeviceNet PD Configuration parameter. In MC_SHELL or FBG31C, the setting is displayed by means of the DeviceNet PD Configuration = 3 PD parameter or 3PD + Param .
  • Page 15 Project Planning and Startup Configuration for two process data words Process data length = 2 can be set using the DeviceNet PD Configuration parameter. In this case, 2 PD or 2PD + Param must be set in MC_SHELL or FBG31C. As a result, two process data words (4 bytes) are processed in the inverter and two process input data words are sent to the control.
  • Page 16 Project Planning and Startup Configuration for one process data word Process data length = 1 can be set using the DeviceNet PD Configuration parameter. In this case, 1 PD or 1PD + Param must be set in MC_SHELL or FBG31C. As a result, one process output data word (1 byte) is processed in the inverter and one process input data word is sent to the control.
  • Page 17 Project Planning and Startup If a timeout occurs for the polled I/O messages, this connection type enters timeout status. Incom- ing polled I/O messages are no longer accepted. The timeout response triggers the timeout reaction set in the inverter. The timeout response can be reset with DeviceNet by using the reset service of the connection object (class 0x05, instance 0x02, undetermined attribute), by dropping the connection or by using the reset service of the identity object (class 0x01, instance 0x01, undetermined attribute).
  • Page 18 Project Planning and Startup Each participant which has received this bit-strobe I/O message responds with its current process input data. The length of the process input data corresponds to the process data length for the polled I/O connection. It can also be set using the DeviceNet PD Configuration parameter.
