5 Functionality
5.4.11 Trigger Acquisition
The applied trigger can be enabled or disabled by one or two external signals in the
TriggerAcquisition mode. This mode works with free-running (internal) trigger and external
trigger.
The property
TriggerAcquisition_Enable
enables the TriggerAcquisition mode.
Level Triggered Trigger Acquisition
The Level Triggered mode is enabled by setting TriggerAcquisition_Mode to Level and
TriggerAcquisition_Enable = True . A signal acts as a trigger enable (see Fig. 5.35). This signal is
selected by TriggerAcquisition_StartSource . A high signal level enables triggering of the
camera and a low signal level disables all triggers.
To invert the TriggerAcquisition signal use one of the PLC_Q signal and select
the inverted signal as its source. Table 5.9 shows a setting that uses ISO_IN0 as
trigger enable signal: the inverted signal is used as ISO_IN0 is inverted in the
input logic (see Fig. 7.4).
