Ø  I applied this seq record but it waits for 2 seconds and then turns on the LED. which i don't required. i required Led On for 2 seconds as it takes input and then turns OFF don't wait to turn ON.

 

This means you have not configured the seq record correctly.  I think you must have set the DLY1 field to 2 seconds.  That is not correct. You should do the following:

 

-          Set the LNK1 and LNK2 fields to point to the LED record

-          Set the DOL1 field to 1

-          Set the DLY1 field to 0

-          Set the DOL2 field to 0

-          Set the DLY2 field to 2

 

This will cause the value 1 to be sent to the LED immediately.  It will then wait 2 seconds and then send the value 0 to the LED record.
