A Control system for the XFEL/SPring-8 magnet power supply was designed by using an FPGA program in the "i-DIO" card. This card is modified of the VME field bus card "Opt-VME DIO". An output current deviation, monitoring ADC data from DAC current set value, is checked and makes an alarm signal. The ADC data can be averaged in some special sequences commanded by an upper workstation. A local control system of the power supply is also achieved by the i-DIO. Magnet power supply total system and test operations with the newly developed i-DIO card will be reported.

We develop the prototype control system of XFEL/SPring-8 undulator and confirm the capability of the system. The XFEL consists of the 8GeV linear accelerator and the undulators. The undulator is important for lasing of the intense X-ray beam. For the lasing, the required positioning accuracy of the undulator gap is less than 1 micrometer. We have to control the undulator gap to be less than sub-micrometer resolution. To realize, we control the undulators by the periodic feedback with the linear encoders. In this paper, we will describe detail design of the undulator control system on XFEL.
