6.6.8 Channel-Specific Diagnosis
Definition
The channel-specific diagnosis gives information on channel errors of modules and
expands on the module diagnosis. The channel-specific diagnosis starts after the
module status (if the parameters are preset accordingly). The maximum length is
limited by the maximum total length of the slave diagnosis of 43/64 bytes in DPV0
operation and 128 bytes in DPV1 operation. The channel-specific diagnosis does
not affect the module status.
A maximum of 9 (in DPV0 operation) or 15 (in DPV1 operation) channel-specific
diagnostic messages are possible (see also station status 3, bit 7).
