Controlling Power Supplies on Different Communication Interfaces for Test Systems Used in Industry

This paper presents methods how to interface with power supplies. There will be presented three different power supplies which will be commanded via PC in two programming languages. We chose power supplies which has no existing driver in our programming languages, this way we must communicate with them via a chosen interface with SCPI (Standard Commands for Programmable Instruments) commands. These power supplies can be controlled on different communication interfaces (RS-232, GPIB) and can be made automated programs for making test systems in factories.
