Welcome to the PLCTalk forum community !
Unfortunately you've chosen an old and clumsy conversion for your first post. I was one of the experts on this syntax and troubleshooting... 19 years ago.
Let's take a step back: the PV+ needs a RIO adapter, which was the 2711P-RN6 daughtercard for the old pre-PV+6 hardware. The PV+6 and 7 hardware doesn't support those daughtercards.
What hardware and firmware on the PV+ terminal will you be running ?
Examine your PLC-5 program and document exactly which Input and Output data elements are assigned to the PanelView Standard, and which N-files are used by BTR and BTW instructions in your PLC-5 program.
"N" and "B" files are essentially the same in PLC-5, they're both 16-bit flat data files. The principal difference is in whether your consider them bit-by-bit or as a whole 16-bit signed integer.
Where do you see "the N files are shown as B files" difference ?
Screenshots that are scaled, trimmed, saved as PNG and attached to posts are a great way to share that sort of information with the Forum.
And again, welcome !
