The computer system for control of cw surface-plasma source of negative ions is described. The system provides an automatic handling of source parameters by the specified scenario. It includes the automatic source start and long-term operation with switching and control of the power supplies blocks, setting and reading of source parameters like hydrogen feed, cesium seed, electrodes' temperature, checking of the protection and blockings elements like vacuum degradation, absence of cooling water, etc. The semi-automatic mode of control is also available, where the order of steps and magnitude of parameters, included to scenario, is corrected in situ by the operator. Control system includes the main controller and a set of peripheral local controllers. Commands execution is carried out by the main controller. Each peripheral controller is driven by the stand-alone program, stored in its ROM. Control system is handled from PC via Ethernet. The PC and controllers are connected by fiber optic lines, which provide the high voltage insulation and the stable system operation in spite the breakdowns and electromagnetic noise of cross-field discharge. The PC program for data setting and information display is developed under the LabView.
