The AIC device is an Allen Bradley Communications Protocol enhancer/device. In Rslinx, the PIC/AIC driver is an option for comm drivers. In any case in which you use a PIC box, you would have picked this driver from the RSlinx drivers when you establish communications. The AIC is yet another device used by AB in changing communciation types from rs-485/dh-485/ethernet....etc.
You should be able to upload and download from the PV using the cable that you have specified. I have done it dozens of times........
Are you communciating via the pass-through RSlinx?
If so, specify the PIC/AIC device as a driver.
Also, run the DF1 driver. They may collide in comms because the DF1 uses the com1 port, and most likely so does the PIC/AIC. Only enable one at a time in RSlinx and test comms for both.
You will see the PV in the Linx window upon comms being set correctly, just like processors, other nodes...etc.
Good luck.
Don;t be afraid to ask for more help if req's.
