Analog modules
9.3 SM 336; F-AI 6 x 0/4 ... 20 mA HART
Fail-safe signal modules
262 Installation and Operating Manual, 01/2010, A5E00085586-10
Diagnostic message Possible causes of the problem Corrective measures
HART: Analog output current
specified
Incorrect parameters in the HART
field device
HART field device has simulation,
and simulation is set to a measured
value that is too high or HART field
device is undergoing the measuring
circuit test.
HART: Further status information
available
HART field device supplies additional
status
Read out status of the field device and
correct, if necessary
HART: Configuration has changed The identifier for reassignment of HART
field device parameters has been set in
the HART field device status (=HART
status bytes).
—
HART field device malfunction Error occurred in the HART field device
Check parameter assignment
Replace HART field device
Faulty HART parameters transferred to
module (DS 131 – 136)
Correct HART parameter data record HART parameter assignment error
Error during dynamic parameter
reassignment (HART)
Check the parameter assignment in
the user program
Contact SIMATIC Customer Support
if necessary
HART communication error
HART field device does not reply
Signal fault (level, timing, noise)
Check the process wiring
Check measuring current
Check the current consumption of the
field device
Replace sensor
Increase the number of retries
Connect a capacitor of approximately
100 nF in parallel to the sensor
