This chapter describes how to control the generation of Events to the host application. An
Event is a message that is sent to the host application to notify it of the occurrence of an
internal event.
General Information
The asynchronous message channel is described in the GigE Vision
®
standard and of-
fers the possibility of event signaling. There is a timestamp (64 bits) for each announced
event, which contains the accurate time the event occurred. Each event can be activated
and deactivated separately.
Each event can be activated and deactivated separately (EventSelector).
The charts below show some timings for the event signaling by the asynchronous mes-
sage channel. Vendor-specic events are explained.
EventLost
This signal can be put out when a selected event was lost. The cause may be that too
many events occur.
TriggerReady
This event signals whether the camera is able to process incoming trigger signals or not.
