another confusing OSC result

[mmessing]

So I want to dose my calcium for 10 minutes each hour for 10 doses during the day between 8am and 6pm

When I do this, the pump does not start until 10:01 so only dose for 9 minutes the first time. Then it does 10 minutes the remaining hours, starting on the hour. It's not a lot of volume, but it did confuse me.

So is this correct?

Fallback OFF
OSC 000:00/010:00/050:00 Then ON
If Time 18:00 to 08:00 Then OFF

Thanks, Mark

I think you mean 8:01 rather than 10:01. You have the dose starting on the hour, but the If Time statement keeps it OFF at 8:00. Not until 8:01 is the If Time statement false. Change it to:

If Time 18:00 to 07:59 Then OFF

Right, 8:01. So if I change it 18:00 to 7:59 then then it will start at 8:00. Then each subsequent time it will start on the hour or a minute before? I'm not that obsessive, I'm just trying to understand the programming logic.

Yes.

On the hour.

Remember, the Apex prioritizes top to bottom. So although the OSC was starting at 8:00, the 'If Time' was keeping it OFF. 'If Time' ignores seconds, so up to 8:00:59 is considered 8:00 and the statement is not false until 8:01.
