Big DOH! to Scott the engineer.
John, that's great news, most of the worst case scenario has been avoided.
Tell us what type of operator interface you are using (probably a AB Panel View). If so, and you have access to Panelbuilder saftware, open up the file for the operator interface and it should tell you which node and baudrate it was previously looking for.
If you don't have that information, go online with your processor and do a "save as" and add R1 or something to its name.
Then double click on the comunications (or channel configuration) tab in the project tree under the processor status icon. You should get a popup message allowing you to change the rate and node of the processor. If this is not available or is greyed out, you may not be able to do this online. The same steps apply just if you have to go offline you then have to download the program.
Change the rate to 9600 (RSLinx should warn you of an impending loss of communications) that's ok. If offline do the same and download (you should get the same error message from linx). Once you have changed the rate and or downloaded the program, reconfigure your PCMCIA card to 9600 but leave your node at 0 and you should be ok.
If it then does not communicate to the interface you may have to keep trying node #s 1-31 untill you get the right combo (if you can't determine the PLC node # from panelbuilder). DH485 is limited to nodes 0-31 and no duplicates are allowed (obviously as you have found out in the last 24 hours).
Let us know how you make out with the interface connection.
Good luck
Marc
PS Panelview files are *.PBA or *.PVA and plenty of us have panelbuilder32 who can help you retrieve the node info if needed.
