Subtracting two variables?

[MrEngineer]

Hello there!

I'm looking for a way to set two time variables that can be set on HMI and the third time variable which would be the sum of T1 and T2 ...

Is there any easy way to do it? 

Here's a quick (BUT WRONG) representation of the idea:

Thanks in advance! KR

Just use "Load Timer/Counter Preset" under the Store menu. Also, be aware that you can't activate a Delay Timer (TD) with a transition contact.

Oops, forgot a step. Need to do the Store Timer/Counter Preset after the addition.
