Topic: DMD0065 ND - Trailing Edge One-Shot |
|
When the input logic generates an ON to OFF transition, the Trailing Edge One-Shot (ND) instruction will turn ON the specified bit location for one complete scan then it will be turned OFF.
Note: use the Leading Edge Powerflow Modifier to generate a single one-shot event for multiple output instructions without requiring the use of a bit memory location.

instruction Inputs:This instruction has one ladder logic input.
The gray triangle at the right end of the input leg indicates this input is edge-triggered, meaning that each time the instruction's input logic transitions from ON to OFF, the specified bit location will be ON for one complete scan.

Parameters:Note: Use the F9 key to open the Default Element Selection Tool (the Element Picker or the Element Browser) or use the Down-Arrow key (Auto-Complete) on any parameter field to see a complete list of the memory locations that are valid for that parameter of the instruction.
Pulse - specifies the bit memory location to use. This can be any writable bit location.
