Software and hardware list: Rslogix 5000 v19 1756-L61 FW 19 755T REV 14.01 I saw a May be compatible between the above AOP and Rslogix 5000 19.01,but I don't know if is the cause. I thought could be an option to connect this drive by Ethernet via embedded card ,but may be I will have the same message. I appreciate any suggestion Thanks Silvia [/INST] The old drive had a Controlnet card in exactly the same slot as your new one? Your error messages imply that the old drive had a completely different comm card than the new one. The tech notes are talking about card revisions. Your quoted message implies something like the program is expecting an ethernet card while the drive has a controlnet card. What is the EXACT error message you're getting? Was the old drive a 755T? or just a 755? They are not interchangeable. \\n </s>
