text: <s>[INST] PowerFlex 525 won't communicate with CCW or Logix 5000 Summary: PowerFlex 525 communicates with controller but not CCW or Drive tab in Logix 5000Hi Guys, I seem to have an issue communicating to my PowerFLex 525's via CCW or the drive tab in Logix 5000. I'm trying to change some parameters. I have 5 drives and all of them do the same thing. The PLC is able to communicate without issue. Can anybody think of a reason why my PC is being blocked? Thanks [/INST] What do you see in RS-Linx? Do you see all devices there? Is this the first time this computer has used CCW to communicate with Rockwell devices over Ethernet? It's possible your computer's firewall is blocking CCW. What PLC is working for you? Can you talk with that successfully? What version of CCW do you have? Have you installed the latest drives database for CCW? \\n </s>
