Saving AutoĆTuning Parameter Values
This appendix shows you how auto-tuning parameter values are saved by
reading the auto-tuning status block from and writing the auto-tuning
command block to the 1771-TCM module.
Once auto-tuning is complete, the auto-tuning status block must be read
(block-transferred) from the module to store it in PLC processor memory.
The module’s memory is volatile. Whenever power to the module is
interrupted, the auto-tuning command block must again be sent to it.
The ProSet 700 software handles the block-transfer of these auto-tuning
parameter values transparently so that you do not need to program these
block-transfers, and you have no need to know anything about any of these
values. However, we show you the structure of these blocks just to let you
know what is happening.
