DeviceNet implementation in VAMP relay (Vamp 50, VAmp200, Vamp300) supports two types of communication:
- - Explicit Requests and Responses – used mainly for establishing I/O connections, but can also be used for one time requests to attributes of data model objects.
- - I/O Messaging connections – used for very frequent exchange of process data. Polled, Change of State and Cyclic I/O Messaging types are supported.
