Using I/O Variables (NI Scan Engine)
Webb26 juli 2024 · If there is a LabVIEW or TestStand instance generating the values for the shared variables, you could send the data via UDP or TCP directly to the java application, instead of, or in addition to, writing to the variables. You are able to tie Shared Variables to OPC variables within the NI software. Webb22 apr. 2024 · Global variables are built-in LabVIEW objects. You can use variables to access and pass data among several VIs that run simultaneously. A local variable shares data within a VI; a global variable also shares data, but it shares data with multiple VIs. For example, suppose you have two VIs running simultaneously. how is laiv administered
