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 viewed from the F
OUNDATION fieldbus
™
net-
work. If a password is entered through the local display, the
Transducer Block is taken Out of Service if it is not already
and the User Access or Factory Access will be indicated in
Device Status viewed from the F
OUNDATION fieldbus. 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.
