针对自主研制的基于ARM+FPGA组成的小型可编程控制器,设计了一种手持编程器的编译系统.简单介绍了手持编程器的总体设计,重点介绍了 PLC 源代码指令表的存储与编译.编译时将指令表程序经词法分析、语法分析、语义分析、代码优化、错误处理后生成 PLC 主机能识别的二进制目标代码;存储时采用数组和链表的形式来存放程序.经过测试,该编译系统能正确编译PLC指令表.

A handheld programmer’s compiling system is designed by small Programmable Logic Controller based on ARM and FPGA. This paper introduces the programmer’s design and source code to compile and store. After analyses of morphology, syntactic and semantic, code optimization and error handling, PLC source code instruction list program is compiled to be binary object code identified by PLC host. The programs are stored in the form of an array and chain table. Through the test, the system can correctly compile PLC instruction list.
