GE??IC693ALG223 ---欢迎来电咨询: +++Q PLC核心逻辑是一个状态机。可以根据不同的输入指令执行不同的操作。在设计中。首先应确定需要执行的指令集合,即状态机的指令集设计。然后根据指令集来设计编译器和PLC逻辑功能。PLC指令编译器源程序使用C语言编写。这样。此编译器可以方便地移植到PC、ARM或别的任何支持C编程的平台上。基于图2中的软硬件架构的PLC不能独立运行。需要MCU对其进行相应的设置和辅助。如图3所示。在MCU端。需要一个专门处理与PLC接口的任务(对于多任务操作系统)或程序。 PLC逻辑的工作过程 在MCU端,可以提供相应的PLC人机界面,提供PLC梯形图或指令表的编辑、编译甚至排错界面,当编译完成后。生成可供FPGA内部的PLC逻辑执行的“PLC中间操作码”。当要执行PLC功能时,首先MCU配置FPGA处于“代码下载状态”。并由MCU将编译后的代码下载到FPGA的RAM中:下载完成后。MCU将FPGA设置为“PLC运行状态”。开始依次读入输入和输出端口的状态。并根据所要执行的指令更新状态。最后输出刷新状态。FPGA还有一个“监控状态”。此时。ARM处理器可以直接设置PLC的输入输出10寄存器的值。并可以单步运行PLC中间操作码。ARM结合返回信息。并配合相应的界面,即实现了对PLC的调试。 ********************************* 厦门莫格电气自动化有限公司 联系人:杨丽君(销售工程师) 手 机:/0592-6808374 Q 邮 箱:3443643092@ 传 真:0596-6514751(请备注杨工收) 主营产品:AB,ABB,GE,本特利,福克斯波罗,英维斯,西屋,艾默生,横河 *********************************** 厦门莫格电气自动化有限公司是一家多年专业销售进口自动化系统(机器人系统、分布式控制系统DCS、可编程序控制器PLC、 工业控制通讯转换器 、远端输出/输入模块、人机界面)备件。以停产控制系统零部件、为良好优势、我们有大量库存和盈余操控系统零件、停产的控制系统部分硬件、我们也发布了许多新的硬件和产品来支持你现有的控制系统或运用较新的控制技术、停产的“DCS系统备品 备件 PLC模块 备件”整机及配件系列、有着强大的优势。只要您需要的PLC产品、我们就能帮您找到、公司较具价格优势。 以“专业、 诚信、创新、合作、共赢”的经营理念、不断开发新产品、为客户提供优质服务、以较大限度追求客户满意、并不断开拓新领域业务。 产品直接从境外进货、能够提供不同国别、厂商的设备以及备件、解决您多处寻找的麻烦或对产品质量问题的担心等、在价格上我们有很大的优势、产品详细信息、竭诚欢迎您来电查询! ?
