Hello everyone, I'm seeking some assistance as I'm feeling a bit perplexed. My software had been operating smoothly for the last few months, but yesterday, I encountered a problem when trying to connect to one of the systems. I discovered that every device scanned through RSWho is marked with a yellow question mark, indicating that they are unrecognized. I restored RSLinx, which appeared to resolve the issue temporarily—devices were visible again. However, once I started browsing with RSWho, every device reverted to being labeled as unrecognized. Has anyone else experienced this issue? Any advice on how to resolve it would be greatly appreciated. Additionally, I have reinstalled my software studio (just the latest revision, not a complete reinstall) and the issue persists. I've also deleted the harmony file in hopes of a fix. Thank you for your help! Best regards, Przemek
**User Inquiry: Help Needed with RSWho Device Recognition Issues** Hello everyone, I'm facing some confusion regarding my software. It has been functioning smoothly for the past few months, but yesterday, while trying to connect to a system, I noticed something strange. Every device I accessed through RSWho was marked with a yellow question mark and labeled as an "unrecognized device." I attempted to resolve this by restoring RSLinx, and that seemed to work initially as I could see all devices correctly. However, once I began browsing again with RSWho, every device reverted to being unrecognized. Has anyone experienced a similar issue? I would greatly appreciate any advice or solutions you might have. I've also reinstalled my software studio (though not completely—just the latest revision) and the problem persists. Additionally, I've deleted the harmony file without success. Thank you in advance for your support! **Reply Suggestion: Update RSLinx for Resolution** Consider reinstalling the most recent version of RSLinx. Your EDS (Electronic Data Sheet) database may be corrupted, which could explain the issue you're encountering. RSLinx is essential for identifying devices during your browsing sessions, so restoring or updating it might help resolve the problem.
Hello, I've successfully reinstalled RsLinx, and interestingly, everything functions perfectly within RsLinx itself. However, the only issue appears to be with Studio, specifically concerning RsWho. I also conducted a network scan using RSLogix 5000, which operated without any issues. This suggests that the problem is solely with the Studio software.
When you mention "studio," are you referring to Studio 5000 Logix Designer, which is used for editing ControlLogix programs? Or are you talking about FactoryTalk View Studio, which utilizes RSLinx Enterprise software for controller communication (as opposed to RSLinx Classic)? What versions of each software do you currently have installed? You are right; this issue is unusual. Typically, if RSLinx's RSWho browse feature can detect network devices, then the version integrated within Studio 5000 should also operate properly.
Hello Ken, Yes, when I refer to "Studio," I'm talking about Studio5000. I currently have multiple versions of this software installed, specifically versions 24, 28, and 30. However, it appears that the RsWho feature in Studio5000 isn't functioning properly across all these versions. I encountered issues even when attempting to open a project immediately after launching Studio5000. For your reference, I am using RSLogix Link version 3.91.
Here are my top predictions! It seems the best approach is to refine the launch context that leads to an RSWho session experiencing identification issues.
