error message
Block number
The block number, along with the block ID and the field number
specifies the area from which the data to be sent is taken (and where it
is to be stored in the receiving CPU).
Remember that certain data blocks have a special significance, for
example, DB 0, DB 1 or DX 0 (see programming instructions for your
CPUs). These data blocks must therefore not be used for the data
transfer described here!
If you attempt to use these block numbers, the function is aborted with
an error message.
Field number
The field number indicates the area in which the data to be sent is
located.
