I certainly have the adapters and various cables and have tried any combination of drivers, Auto-Configure or manually, either way, with no success.  I'm looking at the EtherNet/IP Gateway and have priced one at Keathley Patterson for $2139 Thanks for your suggestions!  

My SLC 5/04 is currently connected to a PanelView 1000 having only the RS-232 and using the SLC's bottom RS232 Port.  The PanelView Cable we can disconnect and connect a laptop, go online and troubleshoot problems, BUT we have to disconnect the laptop and reconnect the PanelView to operate the machine. Question:  Which of the other two Ports on the 5/04 could I use for the laptop connection leaving the PanlView connected? Also what cable to use on the 8-Pin Programming Port or the 3-Pin DH+ Port?

I have a very similar cable you linked to but can't get it to work ... maybe driver issue.  Just bought the FC2A-KC2 with USB on one end and the 8-Pin male on the other.

The black cable is the  1784-U2DHP you first mentioned but ours came from Amazon

Thanks for that!  We bought that 1784-U2HHP but found out we needed a gender-changer because the PLC has a female round 8-pin as does the Adapter. That three-cable aftermarket Alternative would probably have the MALE 8-pin but WOW almost $1000 ... may get that. I like the 1756-DHRIO Gateway idea and will pursue that!  Thanks again!
