I am using the 9300 usbs convertor to connect to a SLC5/04 on channel 0. with 1770-kf2/1785-ke/scanport device on rslinx lite 2.43. initially I connected just fine, and could see the SLC and PVs on the DH+ . After downloading the updated program I lost comm with the processor, and cannot re-establish. I have searhed Rockwells knowledge base, and tried several of the fixes, but still a no go. PVs and SLC communicate just fine, the only way I can connect is to wipe the processor back to default, and connect with DH485 protocol. Then cannot re-establish. I cannot find any difference in the channel config from the original. Any thoughts would be appreciated.
