[TRNSYS-users] Changing a parameter to input in components

well, you just have to find the code of the type you wanna change, for
instance type212.for or whatever...then, as David said you have to change
the parameter to input, I'll do it in the code that you pasted before so
that you can see an example, anyway my trnsys function library seems to be
kind of different to yours, but this should work.
Other topic is how to recompile it, I guess you should create a project and
set the right options to the compiler, you've got two options.
1. Copy the options of the project that trnsys created for you with the type
you have built before, those options should be the same
2. Create a new component, create the .tmf with the number of parameters,
inputs and outputs that you want, and then copy and paste the code, be
carefull with this, don't paste the part where you define the number of
parameters or the part with the type number, just the core of the code, I
mean, the part where you carry out the calculations.
I preffer the option 2 because I am too lazy to fight with windows
compilers, but the first option might be better.
When I started programming types I didn't remember much about fortran cuz I
was programming C and other languages (mostly matlab which is the easiest)
for a long time and I had forgotten almost everything from university, it
was a nice exercise to read a code of a type and try to understand
everything. If I were you I'd try so.
Regards and good luck with fortran =)

!Do All of the "Very First Call of the Simulation Manipulations" Here
If(getIsFirstCallofSimulation()) Then
!Tell the TRNSYS Engine How This Type Works
!Call SetNumberofParameters(1) !The number
of parameters that the the model wants
Call SetNumberofParameters(0) !The number
of parameters that the the model wants
!Call SetNumberofInputs(1) !The
number of inputs that the the model wants
Call SetNumberofInputs(2) !The
number of inputs that the the model wants
Call SetNumberofDerivatives(0) !The number
of derivatives that the the model wants
Call SetNumberofOutputs(1) !The
number of outputs that the the model produces
Call SetIterationMode(1)
!An indicator for the iteration mode (default=1). Refer
to section 8.4.3.5 of the documentation for more details.
Call SetNumberStoredVariables(0,0)
!The number of static variables that the model wants stored in the global
storage array and the number of dynamic variables that the model wants
stored in the global storage array
Call SetNumberofDiscreteControls(0)
!The number of discrete control functions set by this model (a value greater
than zero requires the user to use Solver 1: Powell's method)
Return
EndIf
!-----------------------------------------------------------------------------------------------------------------------
!-----------------------------------------------------------------------------------------------------------------------
!Do All of the First Timestep Manipulations Here - There Are No Iterations
at the Intial Time
If (getIsFirstTimestep()) Then
!par = getParameterValue(1) I comment this line cuz u won't need it
anymore
inp1 = GetInputValue(1)
inp2 = GetInputValue(2)
!Check the Parameters for Problems (#,ErrorType,Text)
!Sample Code: If( PAR1 <= 0.) Call FoundBadParameter(1,'Fatal','The first
parameter provided to this model is not acceptable.')
!Set the Initial Values of the Outputs (#,Value)
Call SetOutputValue(1, 0) ! opt
!If Needed, Set the Initial Values of the Static Storage Variables
(#,Value)
!Sample Code: SetStaticArrayValue(1,0.d0)
!If Needed, Set the Initial Values of the Dynamic Storage Variables
(#,Value)
!Sample Code: Call SetDynamicArrayValueThisIteration(1,20.d0)
!If Needed, Set the Initial Values of the Discrete Controllers (#,Value)
!Sample Code for Controller 1 Set to Off: Call
SetDesiredDiscreteControlState(1,0)
Return
EndIf
!-----------------------------------------------------------------------------------------------------------------------
!-----------------------------------------------------------------------------------------------------------------------
!ReRead the Parameters if Another Unit of This Type Has Been Called Last
If(getIsReReadParameters()) Then
!Read in the Values of the Parameters from the Input
File
!par = getParameterValue(1) Since you don't have parameters you won't
need this neither
EndIf
!-----------------------------------------------------------------------------------------------------------------------
!Read the Inputs
inp1 = GetInputValue(1)
inp2 = GetInputValue(2)
!Check the Inputs for Problems (#,ErrorType,Text)
!Sample Code: If( IN1 <= 0.) Call FoundBadInput(1,'Fatal','The
first input provided to this model is not acceptable.')
If(ErrorFound()) Return
! finally where you calculated the value of the formula you should
change PAR1 for IN2
OUT1=IN1+PAR1
! DON'T FORGET TO ADD THE DECLARATION OF THE VARIABLE IN2 AND DELETE THE
DECLARATION OF PAR1
! Note: As far as you declare the variables you can call them with any
name you want, it does not have to be
Double IN1
Double IN2
it could be
Double SPAINWORLDCHAMPIONS
Double whatever
