Data Acquisition and Control

• Implemented within a distributed computing environment

• All items to be controlled or monitoring are accessed via an ethernet LAN.

• Uses Internet Protocols (UDP/IP & TCP/IP)

• The client-server model which is used to build a network of workstations is followed and the data acquisition modules become additional resources on that network

• Experimental control, data readout and real time monitoring of data quality are performed using processors within VME

• Inline data processing and real-time event construction are performed using a multi-processor PC running Linux

• Online data processing and analysis performed using UNIX workstations

• Graphical User Interface using UNIX workstations or Windows PCs

• No master workstation or Central DataBase
