Configure a driver

A driver is the software interface to the computer or workstation hardware that allows the computer to communicate with a network to detect and communicate with a control system device.
  1. In
    Discovery
    , on the
    CIP
     tab, select
    Configure Drivers
    .
  2. In
    Configure Drivers
    :
    • To configure a new driver, under
      Available Driver Types
      , select a driver, and select
      Add New
      .
    • To edit a configured driver, next to the driver name, select
      Settings
      .
  3. (optional) On the
    General
     tab, assign a name for the device.
  4. Under
    Discovery Method
    , select either:
    • Device List/Range
      . A discovery message is sent to each specified individual IP address. The list can identify target devices using the device name, IP address, or IP address range.
    • Broadcast
      . A broadcast UDP message is sent to all devices on the network at once.
  5. In
    Interface
     select the physical port of the computer.
  6. (optional) To listen on port 44818 and update
    Discovery
     in response to network browse requests, select
    Listen on Ethernet/IP encapsulation ports
    .
    TIP: Selecting
    Listen on Ethernet/IP encapsulation ports
     shows your computer in the network tree.
  7. Select
    Tuning
     and configure the tuning settings to change how fast items on the network are discovered.
    • Device discovery poll rate (msec)
      . Defines how often (in milliseconds) the Discovery pane requests data from a device. For example, a poll rate of 1000 ms results in data being requested every second. This setting is inactive when the driver uses broadcast discovery.
      TIP: When a driver makes a discovery request to a device, it waits for the amount of time specified by the Device discovery poll rate before making a request to a new device. Setting this rate to a higher value slows down the rate that devices appear in the browser tree, and reduces the number of messages sent on the network.
    • Offline device discovery poll rate
      . Defines how often (in milliseconds) the Discovery pane waits to try to establish communication with an offline device. For example, a poll rate of 10,000 results in a 10-second delay before additional requests are sent to a device that was offline. This setting is inactive when the driver uses broadcast discovery.
      TIP: Setting this rate to a higher value slows down the rate that a newly attached device appears in the browser tree, and reduces the number of messages sent on the network.
    • Poll interval between discovery cycles (msec)
      . The number of milliseconds that occur between each query of the network by the
      Discovery
       pane.
      TIP: After a driver polls the network branch, it waits the amount of time specified by the Poll Interval between discovery cycles before starting another discovery cycle. Setting the Poll interval between discovery cycles to a higher value reduces the number of network messages sent.
    • Poll timeout (msec)
      . Specifies the amount of time (in milliseconds) to wait for a device to respond to a request.
    • Maximum concurrent packets to this network
      . Used to configure the maximum number of requests that can be waiting for a response on this network at any given time as part of the discovery process.
  8. (optional) Select
    Auto remove offline devices
     to hide offline devices from
    Discovery
    .
  9. Select
    OK
    .
  10. Select
    Close
    .
