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.
