4.3.7 Channel-specific diagnostics
Definition
Channel-specific diagnostics provide information about channel errors in modules and
details of the identifier-related diagnostics. The channel-specific diagnostics start after the
module status (if parameters are preset accordingly). The maximum length is limited by the
maximum total length of the slave diagnostics, i.e., 62 bytes in DPV0 mode or 128 bytes in
DPV1 mode. Channel-specific diagnostics do not affect the module status.
Up to 9 channel-specific diagnostic messages are possible.
The channel-specific diagnostics for the ET 200S with the IM151-1 HIGH FEATURE are
structured as follows:
