The control system allows all other systems to work within the desired parameters, being responsible for sending, reading and controlling the various parameters of the equipment that make up the synchrotron light source. It is a communication network that interconnects all systems and equipment and provides control and parameters to the high level programs that control the source operation with around eight thousand points of control, with about two thousand microprocessor interfaces linked to about 400 computers.

It is a complex system and the major challenges associated with it is to obtain response times of a few microseconds in the various subsystems within the required for a stable and reliable operation of the accelerators, which implies fast communications systems and without the bottlenecks usually acceptable in conventional digital communication systems. The control system will be developed and implemented using the EPICS (Experimental Physics and Industrial Control System) programming and development environment, which is a standard control systems used in many other laboratories.
