Figure 66: Using trigger events to start actions
A stimulus input can be configured to monitor for only one trigger event ID at a time. To monitor more
than one event, use an event blender.
See Event blenders (on page 3-49
) for more information.
Action overruns
An action overrun occurs when a trigger object receives a trigger event and is not ready to act on it.
The action overruns of all trigger objects are reported in the operation event registers of the status
model. Please refer to Status model (on page 5-14, on page E-1
) and the appropriate sections on
each trigger object for further details on conditions under which an object generates an action
overrun.
Digital I/O port and TSP-Link synchronization lines
The Series 2600B has two sets of hardware lines that can be used for triggering: 14 digital I/O lines
and three TSP-Link
®
synchronization lines. These trigger objects can be configured and controlled in
the same way.
The Models 2604B, 2614B, and 2634B do not have digital input/output lines or the TSP-Link
®
.
See Digital I/O (on page 3-83) for more information about connections and direct control of the digital
I/O and TSP-Link synchronization lines.
Common attributes
Mode
Indicates the type of edge the hardware lines detect as an external input trigger. Mode also indicates
the type of signal generated as an external output trigger. The following table describes the hardware
trigger modes for the hardware trigger lines. The hardware trigger modes are described in more detail
in Hardware trigger modes (on page 3-57
).
