The programmable controller as one of the three pillar industries of industrial automation , with its superior performance, high reliability, ease of development and maintenance , etc. , play an increasingly important role in the field of industrial production . With the development of micro-electronics technology , computer technology , and the increasing promotion of international standard IEC61131-3 , embedded systems and soft PLC technology combined into a new direction of development of PLC technology , soft PLC system based on embedded technology (embedded soft PLC ) has become the inevitable outcome of the development of PLC . The CASS is based on pioneering research of embedded technology PLC system . This paper the CASS - based technology , the problems encountered by the winding machine industry , the winding diameter is greater than 0.8mm multi-layer coil bobbin flange prone jumpers and stacked lines , the nonlinear winding algorithm . The algorithm PLC embedded NC instruction , relative to the current common winding algorithm , has a certain pioneering and innovative . The main work and research can be summarized as follows : (1) the numerical control technology, the development status of the winding machine industry , as well as the current problems encountered , briefly , to prepare for the further study of this thesis . (2) Winding algorithm with the traditional use of engine control and PLC industrial control , embedded in the PLC CNC language , winding machine winding . (3) nonlinear algorithm designed winding CNC instruction , the instruction design includes the design of the underlying instruction and instruction scheduling , the ladder instruction design and functions , the design of the winding CNC instruction and command analysis compiled download and instructions management . ( 4) According to the non-linear algorithm to build the test platform , and the algorithm was tested , the test results show that : the nonlinear algorithm is applied to the cable winding machine is feasible, and has a good winding , algorithm design flexible , scalable , stable and reliable control system , with some ground-breaking and practical value .
