Configure Network VI

use binding? specifies whether LabVIEW binds the shared variable to the URL that you specify in the URL text box. The default is FALSE.

URL specifies the path to the shared variable or data item to which you want to bind the shared variable. The format of the path to an NI Publish-Subscribe Protocol (NI-PSP) data item is \\computer\process\data_item.

access type specifies how you want to access the shared variable.

buffer size specifies the size, in bytes, of the NI-PSP buffer. The default is 50. You must set use buffering? to TRUE before using this input.

use buffering? specifies whether LabVIEW enables NI-PSP buffering for the shared variable. The default is FALSE.

single writer? specifies whether the shared variable accepts value changes from only one target at a time. The default is FALSE.

By default, multiple targets can write to a single shared variable at the same time. The Shared Variable Engine (SVE) processes the requests to write to the shared variable in the order in which the requests arrive. If this input is TRUE, the SVE restricts writing to a single VI on a single computer. The first writer that connects to the shared variable can write values and any subsequent writers cannot. When the first writer disconnects, the next writer in the queue can write values to the shared variable. LabVIEW notifies writers that cannot write to the shared variable.
