It is possible to interface multiple parameters though SimKEy. There is also the possibility to configure multiple instruments through the program's setup feature, but there is nothing about the Ge Proficy. I have looked everywhere, but I couldn't find the requested information. No website is configured to hold information about Ge Proficy.
To download the program, access the official website: http://ibr.com/IBR_E.htm
You can also read more about the programs as well, using the same website and the menus available on the navigation section.
