Inside Event Detection States. Figure 1-38 illustrates the operation
of an arbitrary event detection state named . Typical

, and STOP.

Normal downward execution is controlled by the source command.

SOURce

The : : SOURce command specifies which particular

input can generate the event required to continue the downward
path. If the source chosen is a non-analog signal, such as IMMediate,
BUS, or

, no further qualifications are required to generate an

event. If, however, an

or

analog signal is chosen,

additional qualifications may apply. You specify these additional
qualifications using appropriate

and

commands. Sending

sets the SOURce to IMMediate.

The downward path also provides a command to override normal
operation.

IMMediate

The : : IMMediate command bypasses event detection,

and

qualifications one time. The upward path

through the event detection state contains only one condition. A

: :

command sets the number of times the

trigger system must successfully exit that event detection state on a
downward path. If this condition is satisfied, the trigger system exits
upward.
