Substatus
Measured value cannot be used
Measured value uncertain
Measured value OK
Parameter error, i.e. upper and lower value for meas‐
uring or output scale identical
RAM or EEPROM defective;
Diagnostic bit "Memory error" is also set and the diag‐
nosis message "RAM error" or "EEPROM error" dis‐
played locally
Measurement was not possible;
Diagnostic bit "Memory error" is also set and the diag‐
nosis message "Measuring path fault" displayed locally
Corresponding function block is in "Out of service"
mode (see parameter "MODE_BLK actual")
Measurement contains too many implausible meas‐
ured values, e.g. due to solids or gas bubbles in the
medium.
Diagnostic bit "Memory error" is also set and the diag‐
nosis message "RAM error" or "EEPROM error" dis‐
played locally
Failsafe mode: the current measured value has been
replaced with the last good measured value
Failsafe mode: the current measured value has been
replaced with the agreed failsafe value
Failsafe mode or state before the first measurement:
the current measured value has been replaced with
the start value
Measured value is outside the sensor limits
(Table 5-1, Page 30)
Measured value is OK (normal state)
A parameter with the "static" memory attribute has
been changed locally or on the PROFIBUS
