Definition of host and field devices is a process where as a host product is chosen to provide a network, tool set and graphic user interface (GUI) capable of hosting all stand alone systems and field devices of an open operable protocol.

 In order to assure success in this task, samples of the field devices and stand alone systems must be collected and tested by binding to the host. This definition process delivers positive answers as to:

1. Host to field device compatibility
2. Available network variables
3. Value of binding specific products to network
4. Uncovers unexpected gateway equipment expense
5. Host network, tool set and GUI capabilities
