Considering that Open() and TPDI_POWER() functions are called fine, I think that the problem is with the (out) parameters passed by reference that cannot be processed by JScript.
See http://support.smartbear.com/viewarticle/31116/ for more details and especially consider the last but one paragraph.
As a possible workaround you may consider either to create a ScriptExtension (http://support.smartbear.com/viewarticle/28456/) and implement it using VBScript (that do not have problems with the parameters passed by reference) or create additional DLL that will wrap the call to TPDI_READ_Powerconsumptionvi() and return results in a way compatible with JScript.
