【产品详情】

此功能支持模拟 DCS 操作的速度调节，范围为 0.1 X 正常速度（即正常实时速度）到 10 X 正常速度（即比实时快 10 倍）。默认值为 1 X。这将使 DCS“看起来”比真正的 DCS 工作得更快（或更慢）。使用此作为减少“超时”或“浸泡”操作期间的等待时间，或加快某些培训活动的方法。减少从空白初始状态启动工厂时生成各种训练场景所需的时间。 

注意 – 此节流功能对计算机上的 CPU 速度和 CPU 使用率很敏感。当您第一次尝试使用此加速功能时，请慢慢增加速度并在任务管理器中观察 CPU 使用率。不要让 CPU 使用率超过 70%，否则可能会导致意外的模拟器结果，并且可能需要重新启动计算机。如果您的计算机有大量备用 CPU 容量，这将不是问题。但是，如果您的计算机没有足够的容量，则必须避免使用较高的设置。 

可控硅(Silicon Controlled Rectifier) 简称SCR，是一种大功率电器元件，也称晶闸管。它具有体积小、效率高、寿命长等优点。在自动控制系统中，可作为大功率驱动器件，实现用小功率控件控制大功率设备。它在交直流电机调速系统、调功系统及随动系统中得到了广泛的应用。

可控硅分单向可控硅和双向可控硅两种。双向可控硅也叫三端双向可控硅，简称TRIAC。双向可控硅在结构上相当于两个单向可控硅反向连接，这种可控硅具有双向导通功能。其通断状态由控制极G决定。在控制极G上加正脉冲(或负脉冲)可使其正向(或反向)导通。这种装置的优点是控制电路简单，没有反向耐压问题，因此特别适合做交流无触点开关使用。

【英文介绍】

This feature supports speed adjustment that simulates DCS operation, ranging from 0.1 X normal speed (i.e., normal real-time speed) to 10 X normal speed (i.e., 10 times faster than real-time). The default value is 1 X. This will make the DCS "appear" to work faster (or slower) than the real DCS. Use this as a way to reduce wait times during "timeout" or "soak" operations, or to speed up certain training activities. Reduce the time required to generate various training scenarios when starting a factory from a blank initial state.

Note - This throttling feature is sensitive to CPU speed and CPU usage on your computer. When you first try to use this acceleration feature, slowly increase the speed and watch the CPU usage in the task manager. Do not let CPU usage exceed 70%, or you may cause unexpected emulator results and may need to restart your computer. If your computer has a lot of spare CPU capacity, this won't be a problem. However, if your computer does not have enough capacity, you must avoid using higher Settings.

Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driving device to realize the control of high-power equipment with low-power control. It has been widely used in AC and DC motor speed control system, power regulation system and servo system.

Thyristors are divided into two kinds: unidirectional thyristors and bidirectional thyristors. Bidirectional thyristor is also called TRIAC, or TRIAC for short. The bidirectional thyristor is structurally equivalent to two unidirectional thyristors in reverse connection, and this thyristor has a dual pilot pass function. Its on-off state is determined by the control pole G. Adding a positive pulse (or negative pulse) to the control pole G can make it forward (or reverse) conduction. The advantage of this device is that the control circuit is simple and there is no reverse voltage problem, so it is particularly suitable for AC contactless switch use.
