WebApr 19, 2015 · Form what I understand you are trying to build a circuit (using on logic gates) that toggles an LED on the rising edge of the input. You could achieve this without the pulse detector circuit by replacing the D Latch with a D flip flop (which is edge triggered). A D Flip Flop can be constructed from two D Latches and a NOT gate as shown here ... Web1 Bit Memory Address: The Edge Contact requires a Bit Memory Address. The Bit Memory Address can be typed directly into the Address field on the dialog or it can be selected from the Address Picker.

WebMay 31, 2024 · Edge detection. Edge detection is done with a flip flop with the terminal count signal as an input and a two input gate, the type of gate and polarity of it's inputs can be used to select which edge of the event (potentially both with an XOR gate) you detect. One input to the gate from the flip flop, the other the terminal count from the counter. WebOSF = One-shot Falling Edge. This is an output instruction that is on for one scan on the falling edge of the input. Both of your methods accomplish the same thing: When the input bit (either the XIC or XIO) goes from high to low, the output bit (the OTE) will be high for one scan. Here is what they look like in Studio5000:
