Siemens CPU 948 User Manual

The following situations are possible:
•• DB is longer than source area:
If the data block is sufficiently long, you obtain a 32-word long
area per field as shown in the table above.
•• DB is too short:
If the end of the data block is within the selected field, in the last
field an area with a length between 1 and 32 words will be
transferred.
•• Field is outside the DB:
If the first data word address of a field is not within the length of
the data block, the SEND function detects and indicates an error.
