SIT Connection Manager Has Slow Responsiveness and Updating Primary Software: LabVIEW Toolkits>>Simulation Interface ToolkitPrimary Software Version: 3.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: When I have a small amount of mappings inside my Simulation Interface Toolkit (SIT) program my SIT Connection Manager works well. As my program grows and I add more mappings the SIT Connection Manager updates very slow. Is there a way to improve the performance? Solution: While the SIT Connection Manager is open it polls the mapped parameters and updates their values. The default rate at which the parameters are updated is 500 ms. If the Connection Manager is updating a large number of indicators (often system specific) then 100% of the CPU will be used. The effect is reduced responsiveness to user's commands. Use the Windows® Task Manager to see if the SIT Connection Manager is using 100% CPU. You can change this update rate to fit the needs of the simulation by closing LabVIEW, entering LVSITCMUpdateRate=xxxxx on a separate line of the labview.ini file, and launching LabVIEW again. The labview.ini file is located in the labview\ directory. "xxxxx" specifies the rate in milliseconds at which the Simulation Interface Toolkit updates the Current Mappings table. You can enter an integer between 1 and 10000. If this line is not present in the labview.ini file, the rate is 500 ms.
