Tip: Restore the value of Block 05 (cancel the prior Increment or Decrement
operation)
<< 02 6F 0A 00 00 00 00 01 00 00 00
FF 00 00 00 05 D4 40 01 C2 05 [Checksum] 03
Step 4) Read the content of Block 05
<< 02 6F 0A 00 00 00 00 01 00 00 00

05 FA 90 00 [Checksum] 03
In which, the value = 101 (dec)
Step 5) Copy the value of Block 05 to Block 06 (dec)
<< 02 6F 0A 00 00 00 00 01 00 00 00

FF 00 00 00 05 D5 41 [00] 90 00 [Checksum] 03
Step 6) Read the content of Block 06
<< 02 6F 0A 00 00 00 00 01 00 00 00

FF 00 00 00 15 D5 41 [00] 65 00 00 00 9A FF FF FF 65 00 00 00 05 FA
05 FA 90 00 [Checksum] 03
In which, the value = 101 (dec). The Adr “05 FA 05 FA” tells us the value
is copied from Block 05.
