error code -200000 "Failed writing device link"

[someguy]

I've tried "restore device" and on some of my devices but not all, I get this error.

 

What is this trying to tell me and is there a reasonably simple solution?

 

thanks,

Hi someguy,

 

This could mean two things:

1. ISY could not communicate with the device

2. The device refuses to allow a memory location to be written

 

The best test would be to factory reset the device. If that works, then the issue was the device itself. If not, then we have to figure out where the signal is getting blocked.

 

With kind regards,

Michel

I get the same message. I noticed a communication error message and red exclamation mark appeared in front of a device. I tried to restore the device, but that did not work. I think my PLM is dropping the link for some reason.

The best test would be to factory reset the device.

I did the factory reset at the device. But the restore device on the console shows the same error message. That would mean the device is OK. When I list the PLM Links, the only lines I see for the device are:

002A : E2 00 12.60.E0 01 01 37
002B : E2 00 12.60.E0 01 01 37 

This indicates my PLM lost the ‘A2’ link. The device worked properly earlier today. What is the reason a link is suddenly dropped in the PLM?

Hi sanders2222,

 

Thanks for the update. If ISY still has a hard time writing the links, I am bound to assume we have signal issues. Is it possible at all to move this device (even temporarily) close to the PLM and see if it exhibits the same behavior.

 

During Restore, ISY drops all the links from the PLM, defrags the device database (getting rid of 22s), and recreates everything from scratch. So, if the process is interrupted in the middle, some of the links may not be recreated (as such you may assume they have been dropped).

 

With kind regards,

Michel

Thanks for your response Michel.

Your comment got me thinking that during my original install months ago (linking), I may have had a communication issue with the ISY. Instead, I removed the device from my console, then re-linked it. That added one more link to the count which now includes the send from the device:

002A : E2 00 12.60.E0 01 01 37
002B : A2 00 12.60.E0 01 01 37 

Now I can see the switch toggle in the Event Viewer! So the device is now working properly.

 

I’m sure glad U-D taught me how to use the Show PLM Link Table and Event Viewer tools. That is helping a lot in isolating device and linking issues.
