Status

Along with the measured or calculated PV value, every F
an additional parameter called STATUS. The PV and STATUS are passed from the
Transducer Block to the Analog Input Block. The STATUS can be one of the following:
GOOD, BAD, or UNCERTAIN. When there are no problems detected by the self-diagnostics
of the block, the STATUS will be GOOD. If a problem occurs with the hardware in the
device or the quality of the process variable is compromised for some reason, the STATUS
will become either BAD or UNCERTAIN depending upon the nature of the problem. It is
important that the Control Strategy that makes use of the Analog Input Block is
configured to monitor the STATUS and take action where appropriate when the STATUS is
no longer GOOD.

Master reset method

5.6.1 Resource block
Menu navigation: Service Tools → Maintenance → Reset/Restore
Note
Master reset (sometimes called restart) is performed in the resource block. For block
oriented user interfaces, perform the reset in the resource block.
There are two master reset options. One restarts the transmitter processor but doesn't
change device configuration. The second is a restart with factory defaults. It returns all
device and function block parameters to the factory defaults. An automated procedure
called a Method guides you through both reset options.
