Hello,
according to data sheet it needs to be progammed with PG2000(PL2000).
I personally could provide you PG2000, but I do not have PL2000.
Please see also this link in case you dont know already,
there is some chapters about panelware and also documentation about cable and so on....

In the end I think you should write an Email to B&R support to provide you a download link for PG.2000 as well as PL.2000 (I guess it is this what you need to change the display, PG.2000 for the PLC control changing).
hope it helps,
