10.3 PROFINET IO Diagnostics
PROFINET IO allows exact diagnostics of the type and source of an occurring
error by reading the record data sets for the diagnostics.
The respective configuration software / IO supervisor is normally used, which
provides graphical processing of the diagnostic data (e.g. STEP 7, etc.).
In addition to the record data sets for module/submodule parameterization, a
number of record data sets are available for acyclic communication for
diagnostics (listed in the following section).
The structure of the standardized diagnostic data sets and channel-specific
diagnostics are then explained.
Standard and manufacturer-specific diagnostic data sets are mapped according to
the extended channel diagnostics.
10.3.1 Diagnosis Data Sets
The diagnostic information of the fieldbus coupler (IO device) can be read
acyclically using standard diagnosis data sets (records). The structure of the data
sets is defined in the PROFINET IO specification.
More details are available in the specification under “IODReadReq” or
“IODReadRes”.
The data set number (index) makes it possible to distinguish between the
diagnostics level (device, module, submodule or channel error) and the
diagnostics structures.
The list of diagnosis data sets listed below provides the respective message
structures in the case of pending diagnostics.
