Dynamically Modify the XNET Database or Signal List for XNET Create Session

The XNET Create Session VI (Signal Input or Signal Output) requires a signal list  to specify, which signals of the CAN database will be read or written.
 

• Can I dynamically alter the database, i.e. use another alias  that includes signals of the same name?
• Can I dynamically modify the content of the signal list array and replace or remove certain signals?

XNET Create Session will also accept an array of strings as a signal list instead of the dropdown elements. You can use one of the following syntaxes to specify the used signals and databases.
 

• <signal>\n<dbSelection>
• <frame>.<signal>\n<dbSelection>

You can use the the LabVIEW string functions to dynamically modify the signals and databases at runtime. Here is an example on how to alter the used CAN database of a signal list.
