The following diagram shows an example of the extended diagnostic data sent to the
Profibus master by the MM200. The extended diagnostic data is only provided when one of
the states listed in the above extended diagnostic table has become true. In this example,
the extended diagnostic data has been sent because the "External Start A Alarm" is active.
Such a case would occur when the motor status is running, but no Start A control was
issued by the MM200.
Figure 3-7: Profibus - extended diagnostic data
The diagram below shows an example of the standard diagnostic data, which is sent once
to the Profibus master after all Extended Diagnostic conditions become false (when
previously true), or if the master specifically issues a diagnostic data request.
