Simulation of Control System Operation for D.C. Electric Drive Using CoDeSys Programming Medium

Abstract

One of the systems applied for development of programmed logic controller (PLC) software is a CoDeSys programming complex. Its main purpose is to program a PLC and industrial computers in the IEC 61131-3 standard. As a means of PLC programming CoDeSys may be divided in two parts, namely: a programming medium and a programming system. The programming medium is to be operated using a personal computer in the Windows medium. The paper presents rather interesting tool for graphical laying-out of variable values which is used for adjustment of CoDeSys functions. The tool can be applied for adjustment of not only a personal computer but equipment as well even without writing a programme. Built-in visualization system being applied as in the tool medium so in the PLC (with display) and Web makes some operation more convenient. The given paper reveals CoDeSys capabilities using as an example that is a simulation of a D.C. engine control system with the help of proportional-integral-derivative controller
