VISA Behavior When Multiple Plug-ins Support the Same Module Multiple plug-ins may return information about the same module, this is normal behavior. The following define the appropriate behavior for the plug-in client (which is nominally VISA): If a single plug-in returns that it is the primary plug-in, the client should use it. If no plug-in returns that it is the primary plug-in, but several plug-ins support a module, the client is permitted to use a vendor specific algorithm to choose one. If multiple plug-ins return that they are primary, the client is permitted to use a vendor specific algorithm to choose one or flag an error.
