In a system for a field asset site having a plurality of field assets, a first transport module interfaces with a first field asset, the first transport module operable to communicate via a first transport with a communication center outside of the field asset site. A second transport module interfaces with the first field asset. A third transport module interfaces with an associated field asset and is operable to communicate via a second transport to the second transport module. Each of a plurality of audit devices interfaces with an associated field asset from which operation data is acquired by the audit device. Each of a plurality of routing modules interfaces between an associated field audit device and at least one of the second transport module and the third transport module, with each routing module operable to provide transport-agnostic communication between its associated audit device and at least one of the communication center and another audit device.
