Issue
Not possible to download a MTA file to a Xenta from the System Plugin.
The download was really slow and finished with an error.
When the Xenta was decommissioned in Lonmaker it was possible to do the download.
Environment
Tac Vista 5.1.7
System plugin 5.1.7
Lonmaker
Cause
The download problem is probably due to too much traffic to or from the Xenta on the Lon channel or that the Xenta have to much to do.
If the problem is too much traffic to the Xenta is most likely to the I/O modules, one reason I have seen before is that an I/O module is specified in the Xenta but it doesn't exist, then the Xenta will try to reach it over and over again and it is very hard to get a download of the mta to work.
Resolution
Workaround to get the mta file down:,
- Decommission the Xenta,
- Download the file
- Commission it again.
To solve it check that no I/O modules is specified in the Xenta which don't exist on the network.
