  • Page 8: Installation

    Installation WARNING! Before installing, ensure that the drive wiring is electrically isolated and cannot be made “live” unintentionally by other personnel. Wait 5 minutes after disconnecting power before working on any part of the system or removing the covers from the drives. To Remove the Control Board 1.
  • Page 9 Fitting the Option The Option fits on to the Control Board. 1. Insert the connector into the Option as shown. The legs of the connector will protrude through into the connector on the other side of the Option. 2. Press the assembly into the TOP connector (adjacent to terminals X13, X14 and X15) on the Control Board.
  • Page 10 Re-fitting the Control Board 1. Slide the board into the drive, engaging the edges of the boards into the slots. Push until the back edge of the Control Board PCB locates with the connectors in the drive. 2. Tighten in position using the top and bottom screws in the handles of the Control Board. 3.

  • Page 11: Wiring The System

    Wiring the System DeviceNet is a 4-wire system. Two wires convey the DeviceNet data and the remaining two wires convey power if the product is remotely powered. Remote powering is recommended and is necessary if the network is to remain operational between other devices when the drive is powered down.

  • Page 13: Setting Mac Id And Baud Rate

    The DIP switches allow you to select 6 bits for the MAC ID and 2 bits for Baud Rate. NOTE If all 8 bits are in the ON position, MAC ID and Baud Rate are set by software. If the DSE DeviceNet function block is instantiated then this has precedence over the MMI. 8903/DN Binary Function Example...

    Step 1.3: Configuring the Fieldbus Connectors Double-click on the function block to display the dialog below. The fieldbus connectors (inputs and outputs) are assignable in the function block along with their data type to/from the PLC. The Baudrate and MAC Id can also be selected. An Input may be configured to be either Polled or Explicit.

  • Page 20: Devicenet Status Information

    DeviceNet Status Information The DeviceNet function block in DSE provides status information about the DeviceNet network interface. When online, the actual MAC Id in use can be found by clicking the right mouse button over the “MAC Id:” text and selecting Get. This may be different to the MAC Id set in the function block configuration if the switches on the Option have set the Address.

  • Page 25 Click OK. 4. Download the completed configuration into the PLC, ensure that the PLC is in the PROG mode. For example, the SLC-500 has a keyswitch to select this. Then go online to the DeviceNet network by clicking the Online button: The system will scan the online network and add a status flag against each device as appropriate.

  • Page 26: Polled Inputs And Outputs

    Polled Inputs and Outputs The Poll command is a message that is transmitted by the Master. It is directed towards a single, specific Slave (point-to-point connection). A master must transmit a separate Poll message for each one of its Slaves that are to be polled. The Poll-Response is an I/O message that the Slave transmits back to the master when the Poll Command is received.

  • Page 28: Change Of State (Cos) And Cyclic Outputs

    Change Of State (COS) and Cyclic Outputs A device only sends a Change of State (COS) / Cyclic Output message when either data has changed or after a pre-defined timer expiry (heartbeat). Both the mode and cycle time are defined by the PLC. The 890 supports a single Assembly Object for COS / Cyclic Output.

  • Page 29: Explicit Messaging

    Explicit Messaging Through explicit messaging, the DeviceNet option provides the ability to access parameters within the 890 drive. Explicit messages are identified by a class number, instance number and attribute number. The Write and Read access is possible with the DeviceNet Common services: Get_Attribute_Single ( Read) Set_Attribute_Single (Write) Two vendor specific class, 0x64 and 0x65, are provided to allow access to 890 fixed parameters...
