REQ
Input
BOOL
Valid on rising edge
BUF_FORMAT
Input
BOOL
TRUE indicates that the buffer data
is in MOTOROLA format ;
FALSE indicates INTEL format
BUF_OFFS
Input
DINT
The starting byte number of the
buffer being converted,
0
is the first byte
of the buffer
BUF_CNT
Input
DINT
The number of bytes converted in
the buffer
BUFFER
Input - output
ARRAY
Buffer, a byte array
DST
Input - output
Array
or ANT
The storage area, the content of the
converted byte is placed here, the type
of DST should be consistent with the
specific BUF_TO_* type, such as the DST
of the BUF_TO_BYTE instruction must
be BYTE type
DONE
Output
BOOL
After the conversion is complete,
set to
1
until
REQ
is
0.
ERROR
Output
BOOL
The conversion is normal,
0
,
otherwise set to
1
STATUS
Output
INT
If the conversion is not normal, an
error code is given, as shown in the table
below.
