The statistical process
monitor in the device
diagnostics has reported
that a user defined limit
was exceeded.

1. Check the statistical process monitor
status in the diagnostics transducer
block.

LOI Failure Communications failure
with LCD.
LCD will lose local
PV Indication
Check Display
and Sensor
Connections.
The Fieldbus Electronics Board has
reported a Local Display failure.
1. Check Local Display connection.
2. Check the interface cable between
the Sensor Module and the Fieldbus
Electronics Board. (Sensor Module must
be connected).
3. Replace the Local Display.

NV Writes
Deferred
A high number of
configuration changes
have been detected. To
prevent premature
memory failure, the write
operations have been
deferred; the transmitter
must remain powered
through completion to
avoid data loss.
The device
continues to work
as is with no affect
to the PV's. Barring
a power cycle by
the device, the
software will
eventually save the
NV data and the
error will clear.
Limit the
number of
periodic writes
to all static or
non-volatile
parameters.
A high number of writes has been
detected to non-volatile memory. To
prevent premature failure of the memory,
the write operations have been deferred.
The data will be saved on a 6 hour cycle.
This condition usually exists because a
program has been written that writes to
function block parameters not normally
expected to be written to on a cyclic
basis. Any such automated write
sequence should be modified to write
the parameter(s) only when needed. It is
recommended that you limit the number
of periodic writes to all static or
non-volatile parameters such as
HI_HI_LIM, LOW_CUT, SP,
TRACK_IN_D, OUT, IO_OPTS, BIAS,
STATUS_OPTS, SP_HI_LIM, and so on.
