Fieldbus Communication Gas Temperature Transmitter Self - diagnostic

Fieldbus Communication Gas Temperature Transmitter Self - diagnostic

Quick Detail:

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.

FEATURES:

● Interoperability
FOUNDATION Fieldbus specifications grant the
interoperability of the field instruments without
preparing designated softwares for the instrument.
● Reduction of instrumentation cost
The multi-drop wiring on the Fieldbus communication
line contributes to the reduction of wiring cost.
● Four AI and DI function blocks
YTA320 Fieldbus model has four independent AI
function blocks whose input can be selected from
Sensor1 input, Sensor2 input, terminal temperature,
differential temperature, average temperature, and
back-uped input. Four DI function blocks can be
used as a limit switch for those temperature.
● Alarm function
YTA Fieldbus models securely support various alarm
functions, such as high/low alarm, notice of block
error, etc. based on FOUNDATION Fieldbus specifications.
● Self-diagnostic function
The reliable self-diagnostic function detects such
failure as measuring range failure and abnormal
ambient temperature, as well as the hardware failure.
● PID function block (option)
PID function block enables field devices to control
processes. Up to two blocks can be specified.
