text: <s>[INST] Powerflex 525 via 25-COMM-E2P Summary: 25-COMM-E2P As Communiation Option Not Appearing In Hardware Selection I have a project that is using two Powerflex 525 drives, one using the embedded IP comms ports, the second using the 25-COM-E2P card to provide a pass-through capability for the IP network. Running Studio5000 V21.00, I have registered the EDS files in RSLinx (V3.6) and in Studio for the 25-COMM-E2P but the card communication option does not show up when I try to add the 525 drive which has the E2P card fitted to it. Also, the AOP files do not install. The Installer does not show any profiles that are to be installed so could this mean that the AOPs for the 525 are already installed? If so, then why doesn't the 25-COM-E2P option show up once the EDS files are installed? Any thoughts and help appreciated. Many thanks, John [/INST] John, not sure where you went to get the AOP. Go here: http://www.ab.com/support/abdrives/webupdate/software.html Go to the bottom left grouping, select the link second from from bottom (RSLogix 5000 Drive Add on Profiles) On the new page, select second link from the bottom again (non-cip motion), and select 520 series. If that doesn't work you might try going here instead: https://download.rockwellautomation.com/esd/download.aspx?downloadid=addonprofiles 3rd link from the top is for 525. The first one I showed you is a 343mb link. This second one, supposedly for the same thing, is an 811mb link. I have no explanation at all for that. I'm downloading both right now. I will install the smaller one first, then the larger. I'm doing that because I do not have the 525 to put into my I/O tree either (same boat as you). I will advise when I have something to report.
