    摘要: Information related to an operational condition of a machine in a process plant is generated, where the generated information is in a first data format. The information may be generated based on data in a second format. The second format may, for example, correspond to a format used by a certain type or types of process entities, whereas the first format may, for example, correspond to a format used to process operational condition information of other types of process entities in the process plant. Providing operational condition data for various types of process entities in a common format may, for example, assist an operator in ascertaining the relative importance of the operational condition for various types of entities.

    摘要: A data transfer system utilizes one or more standard parameters in a fieldbus messaging system as a mechanism to move arbitrarily large blocks of arbitrary binary data into and out of a field device. The preferred embodiment of the invention moves delineated streams of octets across a virtual connection to and from the device by layering and tunneling, utilizing the underlying fieldbus network as a transport mechanism. These octet sequences are referred to as VStreams™. One or more devices on the fieldbus network may have one or more VStreams™ active simultaneously, in either direction. Preferably, a standard multi-byte parameter supported by the fieldbus is defined for use as a window, preferably as large as the underlying fieldbus will allow. Writes to this parameter are interpreted as sequential transfers of data in to the field device. Reads from this parameter are interpreted as sequential transfers of data out of the field device.
