Resolution (Steps to take)
Use clear NVM corrupt method
from host to clear the NVM error.
This method will default the
communication module general
config block NVM data.
Power cycle the device. If the problem
still persists then NVM might be
damaged so need to replace
Communication module.
Used Reconcile model number
method from HART host (DTM/DD) to
recover from this fault. Need to select
correct model number either from
sensor module or communication
board module to reconcile. If the both
module model number are not correct
then change the sensor board.
User can verify the cable/connector
between communication and sensor
board to ensure that it is not
damaged.
Verify by replacing Communication
module If it does not fix the problem,
replace the Sensor Housing.
