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.

Hi

 

If you just want to turn an LED on for 2 seconds and then turn it off I don't see why you need a counter that is updating an integer count at all.  For example the "seq" record in EPICS base can set an output record to 1 (turning on the LED), wait for 2 seconds, and then turn it off.  Each time you process that record it will do that.

get input from ai record. do some calculation in Calc record and then out in bo record.this is the flow of my assignment.
