An Embedded SoftLogic Control System Based on S3C44BOX and IEC 61131-3 Standard

This paper introduces the theory of embedded Softlogic control system based on S3C44B0X controller and IEC 61131-3 standard. The implementation methods of Softlogic control system based on uClinux and IEC 61131-3 standard is provided, and propose an I/O mapping mechanism to solve the problem of relevancy between common I/O variables defined by programming system and the specific physical I/O interfaces. An embedded single neuron adaptive PSD(proportion, sum and differentiation) control system example is given at last.
