1.1 Overview: Purposes of control Protecting people from the X-ray radiation hazard.

Protecting the equipments from damage.

Detecting the position of the X-ray beam.

Controlling the optical components to get the satisfied beam.

Monitoring and archiving the status of beamline, issuing the in

formation of beamline status.

1.2 Overview: Tasks of control

Personnel safety interlock system

Equipment status monitor and protecting system

Diagnosing the beam position with XBPM.

Optical elements motion control

1.3 Overview: Principles of control

Based on an general and standard platform.

Scalable, Reliable and flexible.
