10.4.4 Module 16 – Fragmented entry
PROFINET-IO module identifier
• Module ID: 1016
• Submodule ID: 1
Description
The module defines the transfer of fragmented entry data (direction: from control to device). To occupy few
I/O data, the entry data may be split into several fragments with this module. The fragments can then be
transmitted one after another with a handshake.
These settings act on entry modules 101 … 108. The presence of this module switches on fragmentation of
the entry data.

10.4.5 Module 21 – Result data 1
PROFINET-IO module identifier
• Module ID: 1021
• Submodule ID: 1
NOTICE
Ä
Modules 21 … 28 can only be used one at a time, not simultaneously.
Ä
If the result information (result plus additional information, such as the code quality) does not
fit in the selected module width, the information is shortened.
The transmitted result data length is an indication of shortening of the result information.
Description
The module defines the transfer of the result data. The result data comes from the Formatter currently se-
lected. The Formatter can be selected and configured in the webConfig tool (see chapter 9.3 "webConfig
tool").
