Figure 10-6 Diagnostic addresses for DP masters and DP slaves
Special features of CPUs 31xC
With CPUs 31xC you assign two different diagnostic addresses to the slave,
namely one diagnostic address for slot 0 and one for slot 2. These two addresses
have the following functions:
• The diagnostic address for slot 0 reports in the master all events relating to the
complete slave (station representative), e.g. station failure;
• The diagnostic address for slot 2 is used to report events at this slot, that is,
with the CPU operating as I-Slave it reports the diagnostic interrupts for
operating state transitions.
