I was mainly in the control system for electrical control circuit design, mechanical, hydraulic control system for a basic description only.  In this paper, the design of the control system in hardware design, first of all to identify with the electric drive motor options, and then determine the relay - contactor control system design, the last of the main circuit, transformers, control circuit design, etc. At the same time, control system the core of the control of Siemens from Germany SIEMENSs S7 Series Programmable Logic Controller (PLC) to complete.  In software design using the old design to new and innovative design ladder diagram (Chart menu), the use of SIMATIC S7-200 special programming software STEP 7-Micro/WIN V3.1 on the procedures to prepare, debug, write. In this paper, the four-station modular machine tool and programming controller (PLC) to introduce basic knowledge of the specific implications of this thesis SIMATIC S7-200 modules, functions, use of methods and programming software STEP 7-Micro/WIN V3.2. Combination of detailed design of machine control systems, including design concepts and hardware design steps of the part of software design, component select
