ISaGRAF是一个由软逻辑编程工具完成工业软件包，用于自动化控制应用程序的运行时执行引擎和自定义变量/ OEM开发工具。ISaGRAF的目的是把任何工业计算机为高性能，但价格便宜的软逻辑控制器。ISaGRAF是基于唯一的国际公认的工业自动化控制的编程语言。ISaGRAF是第一个基于Windows的开发环境，完全支持所有五的PLC语言：梯形图（LD）、功能块图（FBD），顺序功能图（SFC）、结构化文本（ST），和指令表（IL）。此外，在动力和弹性极限，ISaGRAF支持功能和功能块编程语言写的。应用范围从简单的机械控制的ISaGRAF高速、复杂过程的高性能和高可靠性的任务。(ISaGRAF is a complete industrial software package consisting of Soft Logic Programming Tools, a Runtime execution engine and custom VAR/OEM development tools for automation control applications. ISaGRAF is designed to turn any industrial computer into a high performance, yet inexpensive Soft Logic Controller. ISaGRAF is based on the only internationally recognized industrial automation control language, the IEC61131-3. ISaGRAF was the first Windows-based development environment to fully support all five of the PLC languages : Ladder Diagram (LD), Function Block Diagram (FBD), Sequential Function Chart (SFC), Structured Text (ST), and Instruction List (IL). Additionally, for the ultimate in power and flexibility, ISaGRAF supports functions and function blocks written in IEC61131-3 languages. Applications for ISaGRAF range from simple machine control to complex processes with high speed, high performance, and high reliability tasks.)
