Assignment
Meaning / Cause
Analog input
•
HART field device is not responding
•
Timing error
•
HART field device did not understand the
command that was sent (1st status byte)
Analog input
•
Incorrect parameters in the HART field
device
•
HART field device is set to "Primary vari‐
able out of range" in simulation mode
•
Incorrect measuring point
•
Parameter assignment of primary varia‐
ble out of range
Analog input
•
The output current of the HART field de‐
vice is saturated:
•
Incorrect parameters in the HART field
device
•
HART field device is set to a measured
value that is too high in simulation mode
•
Incorrect measuring point
Analog input
•
The output current of the HART field de‐
vice is fixed:
•
Incorrect parameters in the HART field
device
•
HART field device is set to a measured
value that is too high in simulation mode
•
Incorrect measuring point
Analog input
In the HART device status (in the 2nd status
byte), the HART field device identifier for
"further status information available" has
been set
Analog input
In the HART device status (in the 2nd status
byte), the identifier for "re-parameteriza‐
tion" of the HART field device has been set
Analog input
In the HART device status (in the 2nd status
byte) the field device reports a malfunction

7.5 Maintenance events
Remedy
•
Check the process wiring
•
Correct the parameter as‐
signment
•
Set current ≥4 mA
•
Increase number of config‐
ured repetitions
•
Check the parameter as‐
signment of the HART de‐
vice
•
Correct the simulation
•
Check whether the correct
measuring transmitter is
connected
Read out status with HART
command 48 and clear error/
cause if necessary
If no diagnostics interrupt is to
be triggered by reconfigura‐
tion, the HART diagnostics
must be disabled.
•
Read out status with HART
command 48 and clear er‐
ror/cause if necessary
•
Replace the field device
