After a rising edge from 0 to 1 at coil BT01T_ the values are copied to the
appropriate range.
Example:
Copying of marker bytes, destination range violation error.
The value of marker bytes MB81 to MB96 is to be transferred to MD93,
MD94, MD95 and MD96. The length is 16 bytes.
Parameters of BT01 function block:
Source range:
>I1 MB81
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
Comparison of marker blocks, range overlap error.
12 bytes are to be copied starting from MW60. MW64 is specified as
destination address.
Parameters of BT01 function block:
Comparison range 1:
>I1 MW60
Comparison range
