Chapter 5 Frame Editor
5-15
DEFAULT
Insert lower 1 byte of the HEX decimal-summing results of data from 2
nd
to [BCC] except the 1
st
date into [BCC]
area. Summing area is fixed. (H[1] ~ [BCC-1])
Calculation Ex.
In exercising frame, add ASCII codes in calculation range of H[1] ~ T[0] in HEX.
(05 + 30 + 30 + 52 + 53 + 42 + 32 + 30 + 30 + 04) = 1E2
Use only lower byte in result 1E2 for BCC
BCC value = (HEX.:E2 / ASCII:4532)
SUM 1
User can set summing area in BCC range area. The other sections are the same as Default.
(Ex. : Set H[0] ~ T[0] in the range if BCC range is to be from the 1
st
data of header to tail)
Calculation Ex.
In exercising frame, add ASCII codes in calculation range of H[0] ~ T[0] in HEX.
(02 + 05 + 30 + 30 + 52 + 53 + 42 + 32 + 30 + 30 + 04) = 1E4
Use only lower byte in result 1E4 for BCC
BCC value = (HEX.:E4 / ASCII:4534)
SUM 2
Function for data mask of BCC calculation results in SUM 1 is added. Masks are classified into &(AND), |(OR),
and ^(Ex-OR). (Ex : In case the mask is set to [& F0] with the setting range of H[0] ~ T[0] by SUM 1 of BCC
type)
Calculation Ex.
In exercising frame, add ASCII codes in calculation range of H[0] ~ T[0] in HEX.
(02 + 05 + 30 + 30 + 52 + 53 + 42 + 32 + 30 + 30 + 04) = 1E4
Use the result from AND calculation between lower byte ‘E4’ and ‘F0’ in result 1E4 for BCC.
BCC value = (HEX.:E0 / ASCII:4530)
