12864液晶中文资料(电路,程序,图片）

带中文字库的128X64是一种具有4位/8位并行、2线或3线串行多种接口方式，内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64, 内置8192个16*16点汉字，和128个16*8点ASCII字符集.利用该模块灵活的接口方式和简单、方便的操作指令，可构成全中文人机交互图形界面。可以显示8×4行16×16点阵的汉字. 也可完成图形显示.低电压低功耗是其又一显著特点。由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。基本特性: 低电源电压（VDD:+3.0--+5.5V）显示分辨率:128×64点内置汉字字库，提供8192个16×16点阵汉字(简繁体可选) 内置 128个16×8点阵字符 2MHZ时钟频率显示方式：STN、半透、正显驱动方式：1/32DUTY，1/5BIAS 视角方向：6点背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10 通讯方式：串行、并口可选内置DC-DC转换电路，无需外加负压无需片选信号，简化软件设计工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃ 12864（带字库汉字显示演示程序）

触摸屏与PLC通讯问题

　　随着计算机网络及现场总线技术技术的发展，PLC及触摸屏在工业控制和楼宇自动化中的应用非常广泛。现场总线技术及其总线接口模块、智能仪表、控制设备等组成的综合监控系统已成为当前自动化技术发展的一个重要方向。在工控领域，PLC与触摸屏结合运用的技术已越来越为工程人员所了解与熟悉 ,由于触摸屏具有操作简便、界面美观直接、编程容易掌握、与PLC通讯良好、抗干扰能力强等等特点 ,它正迅速地渗入各个行业 ,发挥自动化控制的最大优势。　　PROFIBUS提供了两种通信协议：DP、FMS，富士UG系列的触摸屏支持其中的DP协议。富士触摸屏具有很强的兼容性，可以与近30个厂家的PLC通讯，兼容性极强，而且还可以和计算机通讯(开放式通讯协议)。

PLCISM SP3仿真PLC之间的通讯

西门子从PLCSIM V5.4 SP3开始增加了对与PLC之间通讯的仿真能力，但是这种能力仅仅局限于Profibus-S7之间的通讯。 S7通讯是S7系列PLC基于MPI，Profibus，Ethernet网络的一种优化的通讯协议，主要用于S7-400之间，S7-300与S7-40之间的主对主通讯，也非常适合S7 PLC与HMI通讯，例如与操作面板OP/TP以及上位监控软件Wincc的通讯，下面的例子将围绕Profibus网络展开S7的通讯。每个CPU都有资源限制，如过程映像区的大小，计数器/定时器的个数，同样，通信的资源也有限制，在产品样本中有CPU的链接数量指标，这就是指CPU的通信资源。旧版本的S7-300PLC有动态连接与静态连接的区分，动态连接指通过MPI，PLC与PLC通过调用SFC通信的通信连接，调用SFC时连接建立，停止调用时连接仍然维持，通过调用断开连接的SFC才能释放连接资源；静态连接指与HMI的通信连接，当把OP/TP、Wincc连接到同一CPU时会发生有的OP/TP、Wincc连接不上，这是因为使用的连接数已经超过了CPU的连接资源限制，此外还有一个静态连接资源保留给编程器使用。
