Demand Data Exchange (acyclic communication)
In addition to cyclic data communication (PROFIBUS IO standard in compliance
with IEC 61158), PROFIBUS IO also offers acyclic communication services.
These acyclic services run parallel to cyclic data transfer. The data sets are
addressed via the module slots, the sub-module slots and the data set number
(index) of the module. In doing so, the sub-module slot should always be
addressed with 1. The meaning of the indices can be set in the range of 0x0000 to
0x7FFF according to the manufacturer specifications The range of 0x8000 to
0xFFFF is established by the PROFINET IO standard and the following
application profiles.
More information on record data sets for parameterization!
The table in the appendix provides a list of special record data sets for
parameterization of the modules/submodules in the section “Record Data Sets”.
More information on record data sets for diagnostics!
You can read more about special record data sets in the context of diagnostics.
The structure of standardized diagnostic data sets and channel-specific diagnostics
are explained in the section “PROFINET IO Diagnostics”.
