Fieldbus is the digital communication line for the field instruments, whose signal is internationally standardized by Fieldbus Foundation. The Fieldbus bi-directional digital communication performance makes possible for the field instruments and the control devices to be a complete on-line system, superseding the existing analog transmission lines. Also, the precise transmission of various process data including the PV and MV of the field instruments is well established by the Fieldbus multisensing function. Thus, based on FOUNDATION Fieldbus specifications, YTA320 Fieldbus model offers more flexible instrumentation through a higher level communication capability and proposes the cost reduction by multi-drop wirings with less cables.
