Rolf, I am using a current source to send a current proportional to the total number of ampereturns through a resistor. I am planning to use the resistor as an amplification control, but it could be set up differently of course. I connected this function block to measure the voltage across this resistor. The array values models the flux in a particular magnetic material as a function of the ampereturns.
I have not deliberately specified if it is a current or voltage source, I thought it automatically was a voltage source, but maybe that is a part of the problem? You can find the model in the Protel component library, got to; http://www.protel.com/resources/libraries/library_search.asp and search for Generic Components, Simulation and Function Block. The search should return roughly 32 matches on one page. You should find two variants of the model; PWL and PWLR. I am not sure I understand what you mean with 'part type as a parameter', could you explain?

Is it a voltage like with VPWL or a current as with IPWL (with time/value pairs as parameters) ? Where can i find this part 'PWLR', where can i find the library you got it from (what .ddb is it in) ? Maybe the 'PWLR' does take the part type as a parameter (%) ?
