Channel Specific Diagnostics

Errors occurring when configuring and setting the parameters of the station
(IO device) and the connected I/O modules as well as external errors from the
connected periphery are reported by the fieldbus coupler via channel specific
diagnostics. External errors reported by the subassemblies (e.g. short circuits, line
interruptions) are only transmitted to the IO controller after release when setting
the module's parameters.
The "BlockType" in the structure head of the data set corresponds to the value for
the channel diagnostics (0x0010). The length defines the following diagnostics
data for faulty sub-modules or channels.
The data for the channel diagnosis is triggered using a general structure (see
ChannelDiagnosis or ExtChannelDiagnosis).
The respective fault details for the respective channels follow after this. The
general structure has a length of 10 bytes and is composed of as follows:

Channel Diagnostics

The channel diagnostics is set by the fieldbus coupler when external channel
errors occur (e.g., short circuits or overvoltage). These error types are defined in
the PROFINET IO specification.
The error type (UserstructureIdentifier) contains the value for channel diagnostics
(0x8000).
Each error of a signal channel or sub-module is described in a data set (see
ChannelDiagnosisData).
The structure of the data set has 6 bytes and is composed of as follows:
