Hi I recently bought a AB micrologix 1100 plc as a bit of a project to work with at home but I'm struggling to get the plc to talk to the laptop and was wondering if anyone could offer any suggestions. I bought a new laptop (hybrid tablet) it's running windows 8.1 and it didn't have any Ethernet ports so I'm using a usb to Ethernet cable to connect to the plc. I can assign an IP using BOOTP (although I'm not really sure what IP I should be assigning it) but when I go back to rslinx it says unrecognised device and the icon that appears is a yellow question mark it also says comms error on the rhs of rslinx. When I assign it the same IP as my laptop it connects but I get a message which says "can't set port type to 288: no harmony object for this Ethernet" I'm stuck for ideas but I have a feeling it doesn't like windows 8.1 or it could be that it doesn't like the usb to Ethernet adapter. Any help would be greatly appreciated, thanks
