[en] The data monitoring and acquisition system of the 8UD Pelletron accelerator at the Institute of Physics, University of Sao Paulo was constructed in order to monitor on-line the operational characteristics of the accelerator and also to record these electrical, physical and mechanical properties that characterize the operation of the accelerator. These data are stored in text files that are readable and accessible to the users in the local computer network. This system will also help to optimize the maintenance procedures and ultimately setup the parameters for implementation of an self supervision system to operate the accelerator and to tune the beam from the ion source to the users scattering chambers. These text files contain a daily recording of the variables at regular intervals of 1, 60, 360 seconds. This software includes a 6 channel scope mode for local monitoring. In the present version 13 electric variables are read, including terminal voltage, charging voltage and current, triode current, tube and column current, insulation, radiation level and SF6 pressure. Also being implemented 5 other variables: triode position, pellet chain length increment and vacuum in the accelerating tube at the input and output the accelerator. The acquisition system and data distribution is based on hardware platform and software from the National Instruments Company, specifically the language LABVIEW and also using hardware and software developed by the staff of the accelerator.
