In the Trigger tab, you can select the trigger source from the selection list in the Trigger
source field.
As for CH1 and CH2, the trigger event can be selected from a list of predefined standard
events. As an alternative, you can select ”Freely selectable communication object” and
trigger at any communication object.
There are digital and analog trigger sources. Digital trigger sources can only accept the
status yes or no (or active and inactive). Example: DIN7 limit switch 0. Analog trigger
sources can accept any numerical values (e.g. actual speed).
For analog trigger sources, a selection box for the trigger threshold will appear. Triggering
will start when the analog value exceeds or falls below the threshold.
The trigger edge is used to select when to respond to an event:
Symbol
Edge
Trigger
Rising edge
digital trigger: Event occurs
analog trigger: Threshold is exceeded
Falling edge
digital trigger: Event disappears
analog trigger: Threshold is fallen below
Note!
The trigger mode and thus the oscilloscope will only be active, if the RUN /
STOP checkbox is activated in the oscilloscope window!
When the transfer window is opened or the parameter set is saved, the
oscilloscope will be deactivated. Clear the checkbox and check it again to
re-activate the oscilloscope.
In the
Mode
field you can select the trigger time. You can choose between three different
trigger modes:
ƒ
Auto:
Continuous triggering and display, no matter if the trigger condition has been met or
not.
ƒ
Normal:
Triggering and display after meeting the trigger condition. When the trigger condition
is met again after display, triggering will start again.
ƒ
Single:
Single triggering after meeting the trigger condition. After the trigger, the RUN
checkbox will be deactivated and the status will change to inactive.
