1. Specify the buffer where the checksum is to be calculated.
2. Way for checksum calculation (sum of bytes by default)
3. The start address of checksum calculation (in bytes)
4. The end address of checksum calculation (in bytes)
5. Special method for checksum calculation, once choosing this, above selection will be
6. Checksum calculation result
disabled.
Checksum
Select “Checksum” in “device” menu bar, then the dialog box of checksum verification
and calculation pops up.
verification and calculation method is to add up all data from beginning to the end with
byte as the unit. To meet user’s special requirements, he can totalize the data in part of the
addresses in a specified way.
Assume the data at address 0-10(hex system) of data buffer is:
12 34 56 78 90 AA BB CC – DD EE FF 11 22 33 44 55
The character width that can be selected is:
16 bits(2 bytes), the data after exchange is as follows:
34 12 78 56 AA 90 CC BB – EE DD 11 FF 33 22 55 44
32 bits(4 bytes), the data after exchange is as follows:
78 56 34 12 BB CC 90 AA – 11 FF EE DD 55 44 33 22
64 bits(8 bytes), the data after exchange is as follows:
CC CC AA 90 78 56 34 12 – 55 44 33 22 11 FF EE DD
When the type of data in data buffer is Data (HEX/ASCII data), the default
