9.1.14 Logging
• Menu Home | Alarms & Events
In operation, the occurring notifications from the system diagnosis and from the process are
recorded upon a change of state.
9.1.14.1 Show Event List
By selecting the submenu Events the event list is displayed. The display is performed as a
table. The table has only reading rights.
Events are recorded chronologically upon a change of state in an event buffer. The events are
distinguished in 2 classes:
• Diagnosis events (notifications from the diagnosis function)
• Process events (states of signals that are marked as event), refer to
9.1.11.2.1, Configurable Logging and Display of Signal States
When selecting the event list, the most current records (up to 50) are loaded. If more than
50 records are in the event buffer, when scrolling to the bottom the next 50 records will be
loaded. The number of loaded records and the total number are displayed above the table.
The table is sorted chronologically descending (latest event first, oldest event at last), the time
tagging has a resolution of 1 ms. If a new event occurs, this automatically prepended at the
first place of the table. The older events are moved down.
The event buffer contains up to 4096 records and is managed as ring buffer. This means, if
the event buffer has been fully written, the respective oldest record is overwritten by the most
current.
The event buffer is stored non-volatile.
