7.4.5.6.4 Data format PRÜF_SUMME (Check sum)
The data format PRÜF_SUMME supports calculation of a check sum on the basis of a byte wise
exclusive OR link. The CHECK SUM has the following format:
@36,'First','Last', 'Number of characters','Format'@
where
36: Measured value identifier for EXOR check sum
First: Number of character at which generation of the check sum starts. This character is
included in the calculation (counting method starts with 0)
Last: Number of character at which generation of the check sum ends. This character is not
included in the calculation
Number of characters: Number of characters output including any sign
Format: Format of number shown
0: without sign and decimal
1: with sign and decimal
2: without sign and hexadecimal
3: with sign and hexadecimal
Example 1:
With a constant text 'AABBCC' the check sum is to be generated using the characters BB. The
output is hexadecimal with 2 characters:
00UTAABBCC XOR=@36,2,4,2,2@h\0d<cr> <cr> stands for Carriage return (Enter
key)
