Synchronizing Threads In A Multisite Execution Using LabVIEW Reports An Error When Alarms Are Enabled

When synchronizing threads in a Multisite execution using LabVIEW, if an instrument in the test program contains a set of alarms but another instrument in the same session only supports a subset of these alarms, an error occurs.

Workaround:

You may need to assign unique channel group names to each instrument which supports alarms to work around this issue.

Test Limits Editor Regards an Empty String as Search Text

Typing a partial query in the search box of the Test Limits Editor may immediately run a search before you finish typing the remainder of your query. For example, if you attempt to search "pin=vcc", the Test Limits Editor immediately reports: No matches found for "" in column "Pin" after you have only typed "pin=". Continue typing to complete your query to find the results you are searching for.

Workaround:

There is currently no known workaround for this issue.
