HIYou can use the 1747-PIC/AIC+ Driver in RSlinx. With a 2711-NC21 or 22 cable to program the PV. Then use the same cable for the ML1000 connection. The port on the ML1000 will have to be configured for DH485 protocol.
There are issues if you have service pack 3 on your XP PC. See link for a fix for that.

Or use a memory card to program the PV as stated above post #7.
