Diagnostics
General
Fieldbus has the capability of gaining a wealth of information from the field via field devices.
For a control valve, you can determine the status of valves, which have been difficult to
identify without traveling to the field and physically examining them, to some extent from a
distant control room through the information transmitted from the valve positioner. The
FVP110 features diagnostics as shown below.
❑ Set the measurement conditions for the signature(s) you want to measure
( “Signatures and Relevant Parameters” on page 172).
❑ Set SIGN_MEAS_EXEC to select the signature(s) for measurement and perform
measurements.
❑ After the measurement is finished, set SIGN_UPLOAD_DATABASE to select the
data to upload, and upload the values of SIGN_DATA_X and SIGN_DATA_Y.
For self-diagnostics, see “Online Diagnostics” on page 129. For valve parameter
measurement, see “Carrying out Tuning” on page 61 and “Parameters of Transducer
Block” on page 188.
