5. Pen number: Choose a pen to be designated as trigger. Touching the current selection of Pen number opens the
Storing pen select view which listing all available (meaning the enabled pens) tag names.
Function key
Switches the window to pens assigned to
the operation functions.
This key is replaced with Input key while
the window shows Function tag selections.
5.2.4 EVENT RECORDING
In the event recording mode, the 73VR21x detects an external event by trigger signal, and stores preset number of
samples (max. 1200 respectively) before and after the moment of event.
With an analog trigger, the trigger signal is continuously compared with a preset threshold, and the 73VR21x initiates
recording when it is in a pre-determined condition (higher or lower than the threshold).
With a discrete trigger, the signal logic state is continuously monitored, and the 73VR21x initiates recording when it is
turned to a pre-determined state (ON or OFF).
n
Trigger Conditions for Analog
Value > Threshold
Data recording is initiated when the trigger input signal value goes above the threshold
setpoint.
Value < Threshold
Data recording is initiated when the trigger input signal value goes below the threshold
setpoint.
Value ≥ Threshold
Data recording is initiated when the trigger input signal values is equal to or goes above the
threshold setpoint.
Value ≤ Threshold
Data recording is initiated when the trigger input signal values is equal to or goes below the
threshold setpoint.
n
Trigger Conditions for Discrete
Up
Rising pulse edge
Data recording is initiated at a rising edge of the trigger input pulse.
Down
Sinking pulse edge
Data recording is initiated at a sinking edge of the trigger input pulse.
CAUTION !
If you touch Record button while the trigger condition is true, no recording starts until it turns true for a next time.
