OK, first the facts:
You have a 1794-L34 Flexlogix controller, right?
Which of the following communications daughtercards are installed in the controller?
1788-CNC, -CNCR for ControlNet communications
1788-CNF, -CNFR for ControlNet communications
1788-DNBO for DeviceNet communications
1788-ENBT for EtherNet/IP communications
The 1784-PCIC is a PCMCIA card that goes in your computer for ControlNet interface.
The Kepware says it wants an Ethernet connection to the processor using the 1788-ENBT or a 1761-NET-ENI on the serial port. So, do you have an ethernet connection on the FlexLogix controller? Doesn't look like a ControlNet connection is going to help.
