The error message “Number of comparison elements
exceeds one of the comparison ranges” is output.
BC01E1 is 1.
Example
Comparison of marker blocks, range overlap error.
Two marker blocks are to be compared. Block 1 starts at
MW60, Block 2 at MW64. Each block is 12 bytes long.
Parameters of BC01 function block:
Comparison range 1:
>I1 MW60
Comparison range 2:
>I2 MW64
Number of bytes:
>NO 12
The error message “Comparison ranges overlap” is output.
BC01E2 is 1.
Example:
Comparison of marker blocks, invalid offset error.
Two marker blocks are to be compared. Block 1 starts at
MW40, Block 2 at MW54. The block length is specified by the
value of the counter C 01QV.
Parameters of BC01 function block:
Comparison range 1:
>I1 MW40
Comparison range 2:
>I2 MW54
Number of bytes:
>NO C 01QV
The message "The specified offset of the comparison ranges
is outside of the permissible range" is output.
BC01E3 is 1.
J
The comparison is in byte format. MW60 to MW64 is 8
bytes. The number of bytes is 12 bytes.
J
The value of C 01QV is 1024. This value is too big. The
value at
>NO
can be between 1 and +383.
