Embodiment Construction

[0014] see figure 1 , which is a system architecture diagram of a PLC machine code execution method of the present invention, its hardware architecture includes at least one high-performance digital signal processor (1) and a storage module (2), wherein the high-performance digital signal processor (1) ) can also be a microprocessor (MCU), and the storage module (2) can be an external memory or a built-in memory of the processor; and the software part includes at least one DSP main program (3) and a PLC program translation DSP machine code (4); the present invention is to develop a program pointing method, first translate the PLC program into DSP machine code, and include it in the DSP main program, so that the cycle scanning time of PLC will not be limited The transmission speed of the communication interface will greatly improve the responsiveness of the system. In particular, the translation of PLC programs into DSP machine codes can be done in advance before program executio

Abstract

The invention relates to a method for executing a programmable logic controller (PLC) code. The hardware of a PLC comprises at least one high-performance Digital Signal Processing (DSP) and a RAM of a memory module. A software part comprises at least one main program applied to the DSP and a program translated DSP code of the PLC of a cycle ladder diagram. The invention translates a PLC program into the DSP code and executes the PLC code in the DSP. The PLC code is coated in the main program of the DSP so that the cycle scanning time of the PLC is not limited by the transmission speed of a communication interface, thereby the response ability of a system can be effectively improved.
