The spreadsheet to PLC Utility I believe might be one of the most complex tools in AutoCAD: Electrical and one I have not had much time to experiment with.
But if I understand your issue, "How can I get the spreadsheet utility to recognize this module also?", then I believe your problem is this module is not in the PLC database, which is a whole other beast to tackle. However, it is do-able, just takes a lot of patience. :o)
