  • Fieldbus: DeviceNet
  • I/O configuration via the fieldbus
  • Support of both linear and modular (Allen Bradley) configuration systems

  • Automatic I/O configuration (starting with Rev. D0, firmware version 1.23)
  • Integrated terminating resistor

DeviceNet was developed by Allen Bradley as a CAN bus based automation network. It is based on a producer/consumer protocol. From the user's point of view, all data is handled separately from CAN bus transfer possibilities (e.g. longer data packets are automatically fragmented by DeviceNet). Access occurs using I/O messages with defined properties.

The bus controller makes it possible to connect X2X Link I/O nodes to DeviceNet. It has automatic transfer rate detection, auto scan, automatic mapping and automatic configuration of the I/O modules. Explicit messaging, change of state, cyclic, polled and bit strobe are supported as transfer modes. In addition to the standard communication objects, there are also manufacturer-specific objects used to represent the modular X20 System in the best manner possible.

X20 and other modules that are based on X2X Link can be connected to the bus controller. The entire configuration of this type of modular system is supported by the DeviceNet standard. Allen Bradley developed the modular I/O configuration to simplify the necessary configuration steps. The DeviceNet bus controllers from B&R also support this type of configuration.
