You've got a heck of a spectrum of stuff to work on this week, Tim !
Double and triple check that PanelView terminal's part number and network plugs.
2711-B5A1
The "B" means it has Both touch and keypad.
The "5" means a 5.5 inch diagonal screen
The "A" means monochrome; it used to mean "Amber" but that was in the early 90's.
But the "1" means it has a comms daughtercard for Allen-Bradley Universal Remote I/O (RIO).
To connect to an SLC-5/02, that controller would have to be equipped with a 1747-SN RIO Scanner module.
It would be far more common to use a 2711-B5A2, -B5A3, or -B5A5, which have a native DH-485 protocol network port, same as the SLC-5/02 has.
