The comparison result of the function block BC01 is:
BC01EQ = 0, the data block ranges do not have the same
content.
MB65 and MD81 (Byte 2) are not identical.
Example:
Comparison of marker blocks, range violation error.
Two marker blocks are to be compared. Block 1 starts at
MD60, Block 2 at MD90. Each block is 30 bytes long.
Parameters of BC01 function block:
Comparison range 1:
>I1 MD60
Comparison range 2:
>I2 MD90
Number of bytes:
>NO 30
