Using trigger events to start actions
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
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 2600A has two sets of hardware lines that can be used for triggering: 14 digital I/O
lines and 3 TSP-Link synchronization lines. These trigger objects can be configured and controlled
in the same way.

Link synchronization lines.
Common attributes
Mode
Indicates the type of edge the hardware lines detects as an external input trigger. Mode also
indicates the type of signal generated as an external output trigger.
describes the
hardware trigger modes for the hardware trigger lines. The hardware trigger modes are described
in greater detail in
Hardware trigger modes for digital I/O and TSP-Link synchronization lines
NOTE Setting the mode to bypass will not allow the hardware line to be used
for triggering.
Pulsewidth
Specifies the pulse width of the output trigger signal when the hardware line is asserted.
