Hello.
If you have any controllers in your system, it can be done. I show you how do this with AC800M controller, but I think any controller can provide same function.
If Signal_Old > Signal then
Greater := True;
Else
Greater := False;
End_If;
Signal_Old := Signal;
Assign this code to a task with is running every 3000ms.
