The error message “Number of elements exceeds the
destination range” is output.
BT01E1 is 1.
Example:
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 BC01 function block:
Comparison range 1:
>I1 MB40
Comparison range 2:
>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.
CPY mode, copy marker ranges
There is one source range and one destination range. The
source range is specified at
>I1
. The destination range is
specified at
>I2
. The length of the source and destination
range is specified by the number of bytes at the
>NO
input.
The content of the source range is copied to the marker bytes
in the destination range.
The function block executes the copy operation if there is a
rising edge from 0 to 1 at the BT..T_ (Trigger) coil.
The error outputs E1, E2 and E3 are evaluated regardless of
the status of the trigger.
J
The transfer is in byte format. MD93 to MD96 is 16 bytes.
18 bytes were incorrectly defined as length.
J
The value of C 01QV is 788. This value is too big. The value
at
>NO
can be between 1 and +383.
