7.1.2 Device Status Parameter in the
Transducer Block
The following table lists the conditions indicated in the
Device Status parameter. It also shows the affect the condition
has on PV status, Sub-Status and Limit, XD ERROR and
BLOCK ALARM are not affected by these conditions directly.

The first three conditions are Type Mode. If everything is
running normally and there are no Faults or Warnings, then
the device indicates it is “OK” an the local display and in
Device Status. If a password is entered through the local dis-
play, the Transducer Block is taken Out of Service if it is not
already and the User Access or Factory Access will be indi-
cated in Device Status. This will indicate to the operator
that an attempt is being made to modify a parameter value.
No indication is given on the Fieldbus network if someone
is only viewing parameters on the local display.
The next set of conditions is device faults. The device will
most likely not be able to measure level correctly if one or
more of these conditions occur. The condition will be indi-
cated in Device Status and will affect PV Status, Sub-Status
and Limit as indicated.
