Alert Log
The SVI FF keeps a log of the detected diagnostic events embedded in the firmware. The last
32 events are logged in the event log, which can be used to understand the sequence of
diagnostic events. For example:
1. Event --> Low supply pressure
2. Event --> Position deviation
3. Event --> Position LO
4. Event --> Position LO LO
A timestamp is provided for each event. The time for the event depends on the time
distributed on the fieldbus.
When the SVI FF DTM is used to read the events, the DTM extends the number of listed events
as it does not overwrite the oldest existing events when it reaches the 33 event (Figure 90).
