Summary


Choice of LabVIEW for the three layers: Equipment interface in the application layer (VME,

MXI, GPIB, RS232, …) Internet tools for the communication between

applications in the Test Master and Resource Manager layers (FTP, UDP, HTTP, …)

Homogeneity in all control levels Fast development of user friendly applications
