| Abstract: | The Soft- PLC technology is addressed, in which the related concepts and the architectures are mentioned. Moreover, the control schemes between in Soft- PLC and the traditional Hard- PLC are compared concisely. Combined with the practical example of CNC machine tool of control system, it has discussed the working mode of MatPLC development software. Henceforth, the realization process and the caution point of Soft- PLC based- on MatPLC working in Linux OS is explained in detail. As a result, Soft- PLC de- signed can read/write the peripheral IO via PCI interface card. The application of the Soft- PLC technology in embedded CNC system is relatively stable, and saves the cost. |
