03ZSTI4-01-501应用DCS系统PLC板卡模块用非常简单的语言来说，PLC是一种计算机。但大多数人熟悉的计算机使用键盘作为输入设备，使用屏幕作为输出设备。PLC没有键盘。因此，对于输入设备，我们使用“输入模块”，它基本上是一个前面有一排螺丝的小盒子。我们将一堆按钮、传感器、开关等连接到小螺丝上。这将作为我们的PLC“计算机”的输入设备。我们对输出设备做了类似的事情。我们不使用屏幕作为输出设备，而是使用“输出模块”，它基本上是另一个前面有一排螺丝的小盒子。我们将一堆电磁阀、指示灯、电机启动器等连接到小螺丝上。这将作为我们的PLC“计算机”的输出设备。因此，对于假设我们决定使用PLC系统。我们购买PLC并通过连接烤箱和PLC之间的电线进行安装。然后我们从PLC制造商那里买一份编程软件，然后我们为PLC编写一个程序，我们可能会使用“梯形逻辑”编程，因为这是大多数PLC的母语。现在，PLC几乎可以正确控制系统了——除了我们仍然需要一些方法让操作员设置和监控温度——以及启动和停止输送机等等。现在，对于这个小系统来说，一些仪表、按钮和指轮开关可能会很好。我们可以把这些连接起来，为我们的烤箱建造一个操作员控制面板。但另一种（更好的？）方法是使用人机界面。（这以前被称为人机界面，但现在我们必须在政治上更加正确。）所以我们给我们买了一台漂亮的台式电脑和一些HMI软件。我们需要对HMI进行编程，通常这是通过将仪表、旋钮和按钮的图片拖放到计算机屏幕上来完成的。换句话说，我们构建了一个“虚拟”控制面板供操作员使用。我们通过通信电缆将这些屏幕上的控件连接到PLC的存储器。
Now what about the operator control function? Well, one integral part of a DCS system is a large computer (usually a quite powerful one) which looks a lot like a SCADA terminal. And it does exactly the same job. First, it gives the operator a series of control screens with all of the virtual buttons and meters and other whatnots that he (or she) requires in order to control the machinery. Second, it also has the features required to suck the production data right out of the individual controllers - and to store that data in some type of computer database. And in most DCS systems, there is a third function of the DCS terminal: The programming software for the individual controllers is also usually available on this terminal - so that reprogramming the controllers is possible right over the existing data communication cables.Quick review of the DCS approach: The machinery in our factory is being controlled by many individual little controllers. Our operator uses a DCS terminal (computer) to monitor and operate the machinery. This DCS terminal also has features to acquire production data and store it in a database for later analysis. Additionally, the DCS terminal usually has the programming software required for the individual controllers available. And all of the hardware and all of the software required for our DCS system is generally provided by just one manufacturer. Some people think that’s a good thing - and other people think that’s a bad thing.So which is the better approach - PLC or DCS? This is usually decided by the engineers who initially design the factory. And in practice, there are a lot of factories out there who use combinations of the two approaches.
