[TRNSYS-users] Type109-TMY2 slope inputs?

[Charron, Rémi]

Hi Everyone,
I am doing a simulation using Type109-TMY2 to read and analyse my weather data. I want to read my surface slopes and azimuths from a file.  However, it does not seem to work as Type109 uses the default value as opposed to the input value.  Here are three observations:
-If I read from an input file, the default value is used 
-If I enter a constant in an equation and use that as the Type109 input, then it uses the constant from the equation
-If I use an equation that is not constant, then it will use the first value read for the whole simulation, for example, if I use Slope=(Time/100 +35), Type 109 would use 35 slope for the whole simulation.

How can I get around this?  I only need to update the value once at the beginning of the file based on the value from the input file.  However, it seems that the order that the program executes things makes it that the weather file is set before it reads my input file, regardless of the component order that I use.  If the slope was defined as a parameter as it is behaving then I could use Type70 to modify it.
