Hello Aisf138,
As GerdW says, you can use a While Loop to change the value of the LED (True/False) for each iteration using Shift Registers. In Addition, you can add a Wait function to control the "Blinking Time". I share with you a VI Snippet to do this app.
Regards!!!
Sebastian.

Any details? NI is dealing with many kinds of flashing LEDs including
Semiconductor manufacture control to make LEDs that can flash.
Controlling NI and 3-d party current sources to flash LEDs
Design of PCB to make LED driver to flash LEDs
Ethernet hubs flash active LED when transmitting data, if you write network communication, you have flashing LEDs
Above 2 software solutions
ETC...

Hi Asif,
I want one Boolean indicator (LED) to blink when i press toggle switch.
Use the blinking property of the LED indicator, just connect your switch…
i actually want to blink it when logic 1 on any input bit of PLC high
Read "any input bit" of your PLC, OR those bits, wire the result to the blinking property of your LED indicator…

Hi Asif138,
This VI Snippet makes a blinking Led when you press toogle switch using Event Structures and Property Nodes.
Regard!!!
Sebastian.
