A.5 Diagnostics messages and maintenance events
Maintenance messages have no direct effect on the function of the module, of the digital inputs/
outputs or of analog value acquisition. Maintenance events of the HART communication do
not affect the analog value acquisition of the module.

Assignment Meaning / Cause
Module The redundantly configured and intercon‐
nected I/O modules are not compatible.
Module Unable to correctly communicate with the
partner module
Analog input
● HART field device is not responding
● Timing error
● HART field device did not understand
the command that was sent (1st status
byte)
● Running scan because the HART field
device is not set to short frame address
0
Analog input
● Wrong parameters in HART field device
● HART field device is set to "Primary
variable outside of limits" in simulation
mode
● Wrong measuring point
● Parameter assignment of primary
variable outside of limits
Analog input
● The output current of the HART field
device is saturated:
● Wrong parameters in HART field device
● HART field device is set to too high a
measured value in simulation mode
● Wrong measuring point
Analog input
● The output current of the HART field
device is fixed:
● Wrong parameters in HART field device
● HART field device is set to too high a
measured value in simulation mode
● Wrong measuring point
Input/output module AI-DI 16/DQ16x24VDC HART HA (6DL1133-6EW00-0PH1)
Solution
● Check and replace
modules
● Update firmware
● Check the redundancy
connection
● Check the redundant
modules
● Check and replace terminal
block if necessary
● Check the process wiring
● Correct the parameter
assignment
● Set current ≥4 mA
● Increase number of
configured repetitions
● When scan is running, wait
until the HART field device
is found and converted to
short frame address 0.
● Check the parameter
assignment of the HART
device
● Correct the simulation
● Check whether the correct
measuring transducer is
connected
