BECKHOFF KL3361, KL3362: KS2000 Configuration Software |
Trigger Logic
Source
You may select one of the following trigger sources (R40):
Shot | The trigger pulse is triggered by the fieldbus via a control word. | |
Timer | The trigger pulse is triggered at regular intervals by a timer. The frequency of the timer can be specified under General trigger settings. | |
Digital input | The trigger pulse is triggered by the trigger input (24V trigger). | |
Analog input 1 |
The trigger pulse is triggered by analog input 1. |
|
(KL3362 only) |
Analog input 2 |
The trigger pulse is triggered by analog input 2. |
Event
Here you can specify the event (R40) that triggers the trigger.
Rising edge (default) | The trigger unit responds to the rising edge of the input signal. The associated threshold level can be specified via the Trigger values tab. | |
Falling edge | The trigger unit responds to the falling edge of the input signal. The associated threshold level can be specified via the Trigger values tab. | |
Positive pulse longer than set pulse width | The trigger unit responds if the positive pulse width is longer than the configured pulse width, which can be specified via the Trigger values tab. | |
Positive pulse shorter than set pulse width | The trigger unit responds if the positive pulse width is shorter than the configured pulse width, which can be specified via the Trigger values tab. | |
Negative pulse longer than set pulse width | The trigger unit responds if the negative pulse width is longer than the configured pulse width, which can be specified via the Trigger values tab. | |
Negative pulse shorter than set pulse width | The trigger unit responds if the negative pulse width is shorter than the configured pulse width, which can be specified via the Trigger values tab. |
Enable
Connect the lower input of the And gate with the desired function in order to specify when the And gate should switch through a trigger pulse (R40).
Always enabled | The trigger pulse is always switched through. | |
Digital input High | The trigger pulse is switched through, if the trigger input (24V trigger) of the oscilloscope terminal is on High potential. | |
Analog input 1 above threshold level | The trigger pulse is switched through, if the signal at analog input 1 of the oscilloscope terminal increases above the specified threshold level 2. The threshold level can be specified via the Trigger values tab. | |
(KL3362 only) |
Analog input 2 above threshold level | The trigger pulse is switched through, if the signal at analog input 2 of the oscilloscope terminal increases above the specified threshold level 2. The threshold level can be specified via the Trigger values tab. |
Digital input Low | The trigger pulse is switched through, if the trigger input (24V trigger) of the oscilloscope terminal is on Low potential. | |
Analog input 1 below threshold level | The trigger pulse is switched through, if the signal at analog input 1 of the oscilloscope terminal decreases below the specified threshold level 2. The threshold level can be specified via the Trigger values tab. | |
(KL3362 only) |
Analog input 2 below threshold level | The trigger pulse is switched through, if the signal at analog input 2 of the oscilloscope terminal decreases below the specified threshold level 2. The threshold level can be specified via the Trigger values tab. |
Action
Connect the output of the And gate with the desired function in order to specify which task should be triggered.
Reset the timer (chronometer) to zero (R40.2) | Resets the timer back to zero. The timer will start running again automatically immediately. | |
Save timer (chronometer) (R40. 3) | Saves the current value of the running timer at the trigger instant. | |
Set digital output (R40.4) | Sets the digital output, e.g. for synchronous triggering of the second oscilloscope channel of a KL3362. This function has to be enabled by bit 2 of the control byte 1 (CB1.2). | |
Start recording (R40.5) | Starts the recording | |
Enable trigger unit 2 (R40.5) | If the output of the And gate in trigger unit 1 is connected with the function Enable trigger 2, the trigger signal is transferred to trigger unit 2, which can be accessed via the Unit 2 button in the Selection field for parameterization. | |
(KL3362 only) |
Enable trigger unit 3 (R40.5) | If the output of the And gate in trigger unit 2 is connected with the function Enable trigger 3, the trigger signal is transferred to trigger unit 3, which can be accessed via the Unit 3 button in the Selection field for parameterization. |
(KL3362 only) |
Enable trigger unit 4 (R40.5) | If the output of the And gate in trigger unit 3 is connected with the function Enable trigger 4, the trigger signal is transferred to trigger unit 4, which can be accessed via the Unit 4 button in the Selection field for parameterization. |
