For information on block-transfer programming, refer to your
Temperature Control Module User Manual (publication
1771-6.5.120)
To use the Temperature Control configuration software, the read and
write blocks, along with a control word, must be organized into a
614-word data-table interface area in an integer file with the word
offsets shown below. The utility ladder logic provides this.
Word Offset Description
0
Communication control word (initiates blockĆtransfer of configuration
autoĆtune, or gains values when you set a specific bit)
1 Used by the example ladder logic as: BT identity bits
2 Used by the example ladder logic as: BT check mask
3 Used by the example ladder logic as: Cycle sequence number
4 Used by the example ladder logic as: Loop offset value
5 Used by the example ladder logic as: DataĆtable file offset
6 Not used by the example ladder logic
7 Not used by the example ladder logic
8 Not used by the example ladder logic
9 Used by the example ladder logic as: TPO bits Ċ singleĆtransferred
