Introduction
Figure 3-2 Error Message Example
Event Queues
There are several different event queues that are viewed/queried and managed
separately. Note that Conditions are logged in the queues as pairs of events: a
“Detected” event and a corresponding “Cleared” event.
Table 3-1 Event Queue and Display Types
Front Panel
Status (Current
Conditions)
Displayed as a list in the Current Conditions tab of the Status Dialog.
The Status/Current Conditions list shows existing conditions.
When an event is caused by a command sent over a remote interface, the resulting messages are
logged in the queue for that interface. For convenience, such Events are also logged in the Front
Panel queue.
Front Panel
Event History
Displayed as a list in the History tab of the Status Dialog.
The History list shows all the events that have occurred since the instrument was turned on, up to a
maximum of 100 messages.
When an error situation is caused by a command sent over a remote interface, the resulting
messages are logged in the queue for that interface. For convenience, they are also logged in the
Front Panel queue.
Remote
interfaces
When an error event is caused by a command sent over a remote interface, the resulting messages
are output to the queue for that interface. To return an error, you must query the queue for that
interface.
An error event that is caused by a front panel action is not reported to any remote interface queue.
However, a status condition is usually caused by an internal event that is not related to a particular
interface, so the Detected/Cleared Events for status conditions are reported to all the queues.
