WOODWARD 9905-020分配和速度控制模块
产品详情资料：
WOODWARD 9905-020分配和速度控制模块当电池电量低时，某些系统参考位设置为逻辑1。它们是%SA011（LOW_BAT）、%SC009（ANY_FLT）、%S010（SY_FLT）和%SC012（SY_PRES）。最具体的是%SA011（LOW_BAT）。该位可用作梯形图逻辑程序中的触点，以打开控制操作员面板上警告灯的输出（如下面的示例梯级），或向操作员接口终端发送警告。在上面显示的梯级中，WOODWARD 9905-020当PLC检测到电池电量不足时，%SA011触点将闭合。这将打开%Q输出线圈，该线圈处理将打开警告灯的输出模块的输出。另一种方法是将线圈的状态（在这种情况下，可能是%M线圈）传送到人机界面（HMI）终端，例如GE Fanuc CIMPLICITY HMI单元。HMI可编程为当特定位变为逻辑1时显示警告消息。有关系统参考位和梯形图逻辑编程的更多信息，请参阅GFK-0467系列90-30/20/Micro PLC CPU指令集参考手册。WOODWARD 9905-020
WOODWARD 9905-020Certain System Reference bits are set to logic 1 when the battery is low. These are %SA011 (LOW_BAT), %SC009 (ANY_FLT), %S010 (SY_FLT), and %SC012 (SY_PRES). The most specific is %SA011 (LOW_BAT). This bit could be used as a contact in your ladder logic program to turn on an output that controls a warning light on an operator panel (as in the example rung below), or to send a warning to an operator interface terminal.In the rung shown above, the %SA011 contact will close when a low battery is detected by the PLC. WOODWARD 9905-020This will turn on the %Q output coil, which addresses an output module’s output that will turn on a warning light. An alternate method would be to communicate the status of the coil (which, in that case, would probably be a %M coil) to a Human to Machine Interface (HMI) terminal such as a GE Fanuc CIMPLICITY HMI unit. The HMI could be programmed to display a warning message when that particular bit goes to a logic 1.
