Further description of the Fieldbus Node deviceNet

• The DeviceNet is a field bus system based upon the CAN protocol (Controller Area Network). It allows for

the networking of actors and sensors (slaves) with superior controllers (master).

• In DeviceNet, the valve island is a slave according to the fixed and pre-defined master/slave connection set

of the DeviceNet specifications. As an I/O connection variant, polled and bit strobed I/O and Change of
State (COS) are supported.

• With DeviceNet, one decides between higher priority cyclic or event-driven process messages that are sent

and lower priority acyclic management messages (Explicit Messages).
