数控系统内置式PLC的FPGA实现方法

FPGA Implementation Method of Build-in PLC in NC System

提出了一种用FPGA实现数控系统内置式PLC的方法。通过在FPGA内部实现PLC逻辑,并提供能够编译PLC指令的编译器,实现了数控系统对通用PLC编程语言的支持。所述方法在基于ARM+ FPGA的数控系统上得到了实现。

An implementation build-in PLC method using FPGA is put forward. Through realizing PLC logic in FPGA and providing a compiler which can be used to compile PLC command to implement the support of NC system to universal PLC program language. The method based on ARM＋FPGA NC system is real ized.
