Re: [TRNSYS-users] value of times steps

Hi,

There is no need to write component for that. Just use an Excel file filling in Tsky(t+1) and insert that as an input. 

Best Regards,

Arian

Prof Bina,

  Values of outputs at previous time steps can be obtained from Type150 in the standard library or from Type661 in the TESS Controllers library. I am not aware of any components that read ahead in the weather data so obtaining Tsky (or anything else) at time t+1 would require writing a new component.

kind regards,

 David

Hello everyone, 
I hope you are doing well and safe from Covid-19.  
I am seeking a way to call a parameter's value at the desire time step of running. For example, I wanna connect weather to an equation component and write an if statement something like this:
if T_sky(t-1), which shows the temperature of the sky at the previous hour (based on run time step). Or even t+1 for the next time step.
