Theory of Operation
The Anybus-X provides centralized data storage, the “PassageWay TM ”, for data
that is shared between the DeviceNet and Ethernet networks. Data is placed into
the PassageWay by one network interface, allowing the data to be read through the
other network interface.
The Anybus-X appears as a single device on either network using standard proto-
col mechanisms. No special, or extended, protocol features are required of the
devices on either network to read or write the data flowing through the Passage-
Way; all cross-network activity is transparent to the devices on either network.
