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 110 bytes in
DPV1 mode. Channel-specific diagnostics do not affect the module status.
A maximum of 9 channel-specific diagnostic messages are possible in DPV0/DPV1 mode.
