Please help me with the code to dose Kalkwasser in the following way:
Amount to dose:2400 mL
Number of doses: 24
Dose every: 60 min
Volume per dose: 100.0 mL
Pump speed: 50 mL/min
Thanks!

Just use the wizard. It's much simpler and will add the kalk very slowly.

It is too slow! … 7ml/min

How/why is that too slow? Slower is better with kalk because it precipitates substantially and causes pH to spike when added fast

Just use the DOS scheduler wizard. It’s much easier and will result in much more frequent and correspondingly smaller individual doses.
Set it to operate from 0:00 to 23:59 and to dispense a total of 2400ml. Done!

I have a 200 gallons aquarium (RedSea750), 100 ml of Kalkwasser every hour will not affect the PH
That may be so, but I don't understand the want/need to make your programming more complex for the sake of making it dose faster when there is no benefit IME of doing so. The only way to do what you asked is to use profiles, which is easier to screw up. Using the wizard is idiot-proof simple.

I am worried about the life time of the DOS headers,it seems more efficient to me that they dose each hour for two minutes thanevery 13 minutes for 4 minutes.
This is the code:
tdata 00:00:00,1,21,0,218,3,12,110,0,238,2,28,13,0
What do I need to change? Let's go guys!
Ok I give up
Thanks for the help
The DOS head service life is based on two things because it uses stepper motors. Stepper motors are not affected by the number of start/stop operations like your typical submersible pump is.
1. Total volume used
2. Heat (large fast doses cause more heat)
If you want to maximize their life, slower is better.

I found a way to do it
I set up 24 intervals of 100ml each
Each dose is done as follows:

Dosing 100ml at 60ml/min the PH increased from 8.04 to 8.05 in my 200 gallon aquarium
Doing it that way has no tangible benefit but adds much unnecessary complexity. For example, when the time comes to adjust the total daily volume, it’ll be a tedious task to modify all those intervals. If you did it the way zombie and I suggested, it’d just be a single simple & quick change.

I am in agreement with JoseWolf75. Prior to setting up the DOS for ALK dosing I was using a Jeabo doser and adding 100ml every hour. My alk was rock solid. Now I am using the DOS and the same volume is split up for the entire 24hr period but it is not keeping my ALK where it should be. I have upped the dose to a total volume of 4000ml in that same 24hr period and ALK is not steady at all. What would cause that? The other thing I have noticed is that I seem to get air bubbles in the line when running it that slow as well.
