Profile Designation
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
Upper warning limit value has been exceeded or the
lower warning limit value has been undershot below
Upper alarm limit value has been exceeded or the low‐
er alarm limit value has been undershot
The measured value is within the limit values (normal state)
The measured value has exceeded the upper limit (alarm, warning or
sensor limit)
The measured value has exceeded the upper limit value (alarm, warning
or sensor limit)
Measured value remains constant
