	This paper presents an implementation of a multi-channel measuring data acquisition interface of quadrupole and sextupole magnet power supplies (MPS) for Taiwan Photon source (TPS) withLabVIEW as the developing tool. The multi-channel measuring data acquisition interface could reduce quantity of measurement instrument and loading of operator at the MPS acceptance test. The instrument devices of measurement system include a multiplexer 、 a dynamic signal analyzer (DSA) and a multi-channel digital voltage meter (DVM), GPIB is the communication protocol betweenthe multi-channel measuring data acquisition interfaceand instruments. There are threeanalyzing procedure for the output currentof MPSin the default setting of the LabVIEW program, 1) Fast Fourier Transform of output current measured by DSA, 2) long-term stability of output current measured by DVM, 3) the linear error function fitting of output current by LabVEW toolbox;after these three analyzing procedureis completed, the performance of each MPS can be automatically generatedas a Microsoft Word report file.

MOPWA047	Development of a Digital Control Interface Card with a LabVIEW Control Program for TLS Corrector Magnet Power Supply	777
	B.S. Wang, K.-B. Liu NSRRC, Hsinchu, Taiwan
	This paper presents an implementation of a virtual instrument control interface and a digitally controlled interface card for Taiwan Light Source (TLS) corrector magnet power supplies (MPS). Eight pieces of corrector MPS converter module are monitored and controlled by the digitally controlled interface card with delimit boundary of ±10 voltage. The digitally controlled interface card was implemented with an ADS1278 24-bits multi-channel analog-to-digital converter、a DAC8718 16-bits multi-channel digital-to-analog converter and the TMS320F28335 digital signal processor. There are two control modes of the virtual instrument control interface, which are 1) local control mode by RS-232, 2) the remote control by MiiNePort\_E1 TCP/IP protocol; with the developed Labview control interface the user can choose which mode to communicate with the corrector magnet power supplies depending on the working environment.

	The civil engineering of Taiwan Photon Source will soon be completed. The engineering of the power supply cabling should be done in advance of the schedule for the completion of the civil engineering. Using software (SolidWorks) to build a 3-D model, we obtain detailed cabling information because the model is made to scale 1 to 1. As all components are built into the model of the TPS accelerator, we can build accurately a model of the power supply cabling. For example, we can estimate every length and the total cable length for purchase and budget control. We can evaluate the conditions for every power cable to lay the cable tray from the power supply to the magnets, so we can lay every cable to follow the sequence in the cable tray. We thereby convert the drawing of the two-dimensional construction graph when we design the finished three-dimensional cabling model. The excellent and precise results are proved in this paper.
