Rsstudio yellow ?

I'm working on getting some alarms on a panelview plus 1000 on our production line from a plc controlling the hydraulic pumps for this line. All are on the same network and I can see the lines slc505, the pvp and the L306ER in rslinx. When I go into rsstudio to make changes, I open the LinxEnterprise and go to the coms setup, add device. My processor has a yellow ? And I cannot add it to the shortcut. I'm running rsstudio ver7 ( crp9sr6) on a Windows xp machine. As this is out Scala machine with the backups on it. We also have a Windows 7 laptop that has the same version of studio on it but is running 64bit and it can see the L306ER fine. Only problem is if I change the program to work on the 64bit machine I can no longer use to xp machine where all our backups and programing is done from. Any help would be much appreciated.
Thank you all

Quick search on Rockwell's site showed that the L306ER is only supported from v29 and up software.

Does your XP machine have v29 or newer software package installed?

Here is what I would try.

• Unplug your network cable so FTV isn't trying to browse
• Go to the Communication tab at the bottom of you project tree
• Manually add a 1769 PLC instead of the 5069 to your Ethernet driver
• Go to your communication setup, point your driver to the 1769 PLC
• Copy form design to runtime
• Plug in your network cable and test a screen
