[TRNSYS-users] TRNSYS18 Own Component Message 105

[John Dyreby]

Daniel,

The "undefined reference" errors are due to the plotter-specific variables exposed by the TrnsysData module that are not included in the "known" TRNSYS variables that are handled behind the scenes in Type Studio's compiler.  Type Studio started as a mathematical / component-level Type creator, which never considered the need to compile custom online plotter Types.  It may be possible to add that functionality to Type Studio in the future, but I'm not sure it's necessary.

To accomplish what you're trying to do, I would suggest creating an Equation (for a simple integrated unit conversation) or a custom Type (for more complex situations) that outputs the values you expect to plot.  In other words, use Type 65d as-is with the custom output you want plotted calculated outside of it.

Best regards,
John
