8.3.20 Fragmented Reading Result
Module 34
The module defines the transfer of fragmented reading results. To occupy few i/o-data, the
reading results may be split into several fragments with this module. The fragments can
then be transmitted one after another with a handshake.
Notice!
The modules 21 to 27 are designed to transmit data of a length of up to 28 bytes only. If you
would like to transmit longer data, this can be achieved by using Module 34.
