12. 12 LabVIEW - Server Bradley University Department of Electrical Engineering (2011) Server/Client implemented using TCP protocol Server connected to microcontroller, sensors, and hardware using DAQ. – Code complete, need DAQ to test I/O. All backbone code complete and thoroughly tested. – Timing limitations with I/O? Matched TCP calls?

13. 13 Server Limitations Bradley University Department of Electrical Engineering (2011) Single User, Limited Security Move Called – Status only, won’t lock out users User Command Processing – Speed? – Completely untested.

14. 14 Labview Server Code Bradley University Department of Electrical Engineering (2011)

15. 15 LabVIEW - Client Bradley University Department of Electrical Engineering (2011) Actuators, movement call, and commands implemented. Data received from server. Client can terminate connection without interrupting the server. Distribution?
