Fieldbus: DeviceNet8 digital channels, configurable as inputs or outputsSimple I/O configuration via the fieldbusSupport of both linear and modular (Allen Bradley) configuration systemsAuto scan, automatic I/O mapping of the I/OsAutomatic I/O configurationIntegrated connection to local expansion via X2X Link for 39 additional modules (including up to 16 analog modules)1 ms cycle time for local expansion 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 completely separately from the features of the CAN bus (e.g. longer data packets are fragmented automatically by DeviceNet). I/O messages with defined characteristics are used for access.This 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 vendor-specific objects used to represent the modular X67 system in the best manner possible. X67 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.With multifunction modules, the bus controller supports only the default function model in the event of automatic configuration by the bus controller (see the respective module description).
