EthernetIP Communication with Control Logix 5000 PLC
Hi,
I need to communicate with Allen Bradley ControlLogix 5000 series plc over EthernetIP. When I try to import any of the .eds files provided by the plc vendor I am getting an error "No valid Class 1 connections". Has anyone found a way to overcome this problem? Does that mean the .eds files provided are not compatible with AC800M ?
Thanks in advance

Hi ,
fist step is to download the correct EDS from this link

the reference must be the same for ControlLogix

You must load the EDS file of PLC processor (CPU), not load the EDS file of card communication because that not contain Class1 and Class3 connections. For example, if you are connected across a communication card 1756-EN2TXT with a processor 1756-L73XT, you must download the EDS of the processor. It's best to upload processor EDS directly with the RSLinx (Allen Bradley tool) to have the same versions.
