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)

• 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, real time monitoring of data quality, inline data processing and event construction are performed using processors within VME

• Online data processing and analysis performed using UNIX workstations

• Graphical User Interface using UNIX workstations or Windows PCs

• No master workstation or Central DataBase
