CC Function Block Tuning Errors

If an error occurs during the tuning procedure, the tuning is aborted, and an appropriate AtuneStatus value is set. Also, a user can abort the tuning by setting the AtuneAbort parameter.

After an abort, the CV will assume its value before the step change, and the GainTuned, TCTuned, DTTuned, and RespTCTuned parameters are not updated. The AtuneStatus parameter identifies the reason for the abort.
