The code running on the board is halted for the delay specified in the block. The delay can be set in milliseconds, seconds, and minutes. It can range from a minimum of 1 millisecond to a maximum of 9999 minutes, approx. 7 days.
You can set the delay in milliseconds, seconds, and minutes from the range - 1 millisecond to 9999 minutes .
One of the useful applications of this block is when you want to observe a delay between state changes, say the changes in the LED colours.
Introducing a delay between consecutive blocks makes the colour change discernible to the human eye. This application is highlighted in the below example.
