1
device failure
RAM or EEPROM defective;
Diagnostic bit "Memory error" is also set and the diag‐
nosis message "RAM error" or "EEPROM error" dis‐
played locally
sensor failure
Measurement was not possible;
Diagnostic bit "Memory error" is also set and the diag‐
nosis message "Measuring path fault" displayed locally
0

1
out of service
Corresponding function block is in "Out of service"
mode (see parameter "MODE_BLK actual")
0
0
0
0
non specific
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

last usable value
Failsafe mode: the current measured value has been
replaced with the last good measured value
0
0

0
substitute set
Failsafe mode: the current measured value has been

the start value
