text: <s>[INST] Ethernet Conections for PF70 drives Can anyone tell me how many ethernet conections a PF70 drive will take up using two datalinks talking to a ControlLogix? I need this to determine how many EN2T cards I will need in this system. Thanks. Eddie [/INST] Merlin402, a PF70 ethernet/ip card uses only one connection, also if datalinks are all enabled. See also this other thread... it indicates the use of the Ethernet/IP prediction tool, that helps on that. http://forums.rockwellautomation.com/rockwell/board/message?board.id=Drives&message.id=234#M234 - fuzzy logic \\n </s>
