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 total maximum length of the slave diagnosis from 43/62 bytes in
DPV0 mode or 110/128 bytes in DPV1 mode. The channel-specific diagnosis does
not affect the module status.
A maximum of 9 (in DPV0 mode) or 15 (in DPV1 mode with IM151-1
HIGH FEATURE) channel-specific diagnostic messages are possible (see also
station status 3, bit 7).
