and MD81.
Example 4
: Transfer of marker byte, destination range
violation error.
The value of marker byte MB96 is to be transferred to MD93,
MD94, MD95 and MD96. The length is 16 bytes.
• Parameters of function block BT01:
– Source range:
>I1 MD96
– Destination range: >I2 MD93
– Number of bytes:
>NO 18
The error message “Number of elements exceeds the
destination range” is output.
BT01E1 is 1.
Example 5
: Transfer of marker bytes, invalid offset error.
The value of marker byte MB40 is to be transferred to MW54
and subsequent marker words. The block length is specified
by the value of the counter C 01QV.
• Parameters of function block BT01:
– Source range:
>I1 MB40
Destination range: >I2 MW54
Number of bytes:
>NO C 01QV
The message "The specified offset of the destination range
is outside of the permissible range" is output.
BT01E3 is 1.
