Hello, I would like to trigger an alarm if I detect engine malfunctions between 7:00 a.m. and 9:00 p.m.

For example if stpValue \>100 and the time is between 7h00 and 21h00 then I trigger an alarm.

But I don’t know how to know if the time is on the interval of 7:00 a.m. and 9:00 p.m.

You could set up a normal alarm with an execution mode of Above Value for your setpoint, then place an expression binding on the Enabled property that looks something like:

```auto
timeBetween(now(), "7:00:00 am", "9:00:00 pm")

```

Thank you Sir.

That is mean  
if moteur1 = 1 and setpoint = 1 and timeBetween(now(), “7:00:00 am”, “9:00:00 pm”)  
alarm is enabled  
else:  
alarm is not enabled

I can do that?

If `moteur` and `setpoint` are boolean (True or False only) then you can use:

```auto
if moteur1 and setpoint and timeBetween(now(), “7:00:00 am”, “9:00:00 pm”):
    alarm is enabled
else:
    alarm is not enabled

```

Note the ‘:’ at the end of the line.

Be careful. You’re starting to mix scripts and expressions.

`moteur1 && setpoint && timeBetween(now(), “7:00:00 am”, “9:00:00 pm”)`

Thanks, Jordan. Can you clarify what’s wrong with my approach? `timeBetween` returns a boolean so why would my script be incorrect?

`timeBetween` is an expression language function but you wrote Jython script syntax.
