STATus:OPERation:EVENt?
The
STATus:OPERation:EVENt?
query returns an integer representing the value of
the event register for the operation status group.
The event register latches positive transition events from the condition register. A
positive transition event will occur when a condition makes a transition from a low
to a high state. Bits in the event register are latched, and once set, they remain set
until cleared by a
STATus:OPERation:EVENt?
query or *CLS (clear status). There
is no buffering; so while an event bit is set, subsequent events corresponding to that
bit are ignored. Event registers are read only.
Events are queried in order to determine if transitions have occurred since the last
query. They do not indicate the current state (condition) of a particular event. Nor do
they indicate how many times a transition has occurred.
