Process sequence and signal states
No. | PD | Signal states | |
|---|---|---|---|
[1] | Activate length measurement When activated, the feedback "Wait for trigger" (TP PI X:0) is set. | TP PO X:1 | "0": No trigger event is evaluated “1”: The system waits for a trigger event. |
[2] | Trigger After a rising edge at the TP input, the trigger counter is increased by 1 (TP PI X+1). The detected length from this trigger is continuously output via TP PI X+2 and PI X+3. | The acquisition of the trigger signal is set in the configuration. | |
[3] | Trigger After a falling edge at the TP input, the trigger counter is increased by 1 (TP PI X+1). The "Trigger activated (TP PI X:1)" signal is set. The detected length between the two trigger signals is output via TP PI X+2 and PI X+3. | ||
[4] | Deactivate length measurement When activated, the feedback "Wait for trigger" feedback (TP PI X:0) is reset. Additionally, the recorded length in TP PI X+2/X+3 is deleted. | TP PO X:1 | |
[5] | Activate length measurement again When activated, the "Wait for trigger" feedback (TP PI X:0) is set and the length measurement can be performed again. | TP PO X:1 |
