Okay, let's sort out the PanelView to ProLinx connection.
The PanelView Plus has a "DCE" type serial port, and the Mini-8 to DB9 cable from Prosoft is wired as a "DTE" type serial port, so the cable between the two should be a straight-through female-to-female DB9 serial cable.
We can go through the RSLinx Enterprise and Prosoft Configuration Builder configurations either by you describing or posting yours, or by Forum members trying to do it from scratch.
I would build a test application that just put a few numeric indicators onscreen with direct references to "N7:0" and "N7:1" and so forth. The data file numbers and data file length are configurable in the ProLinx but I think the defaults are Data File 7 and 100 elements.
If I were building this system I would try to make the data tables numbers and sizes similar to the Rack Numbers and BTR/BTW sizes, but we can do that later.
Since it doesn't sound like you have connected your development computer to the Prolinx, we aren't going to try to use the Development/Local tab in RSLinx Enterprise. Let's just go straight to the Runtime/Remote tab and right-click to add the driver and the PLC-5 controller that the ProLinx is emulating. I'll do that with screenshots when I get a chance and post it here.
If you have any descriptions, screenshots, or maybe an example from A-B or from Prosoft that you can point to, that might help get us further down the road.
