UNIOP TCM08A 控制板是采用"顺序扫描,不断循环”的方式进行工作的。即在PLC运行时,CPU根据用户按控制要求编制好并存于用户存储器中的程序,按指令步号(或地址号)作周期性循环扫描,如无跳转指令,则从条指令开始逐条顺序执行用户程序,直至程序结束。然后重新返回条指令,开始下一轮新的扫描。在每次扫描过程中,还要完成对输入信号的采样和对输出状态的刷新等工作。PLC的一个扫描周期必经输入采样、程序执行和输出刷新三个阶段。PLC在输入采样阶段:首先以扫描方式按顺序将所有暂存在输入锁存器中的输入端子的通断状态或输入数据读入,并将写入各对应的输入状态寄存器中,即刷新输入。随即关闭输入端口,进入程序执行阶。PLC在程序执行阶段:按用户程序指令存放的先后顺序扫描执行每条指令,经相应的运算和处理后,其结果再写入输出状态寄存器中,输出状态寄存器中所有的内容随着程序的执行而改变。输出刷新阶段:当所有指令执行完毕,输出状态寄存器的通断状态在输出刷新阶段送至输出锁存器中,并通过一定的式(继电器、晶体管或晶闸管)输出,驱动相应输出设备工作。PLC的工作过程,PLC的运行方式初研制生产的PLC主要用于代替传统的由继电器接触器构成的控制装置,但这两者的运行方式是不相同的:
(1)继电器控制装置采用硬逻辑并行运行的方式,即如果这个继电器的线圈通电或断电,该继电器所有的触点(包括其常开或常闭触点)在继电器控制线路的哪个位置上都会立即同时动作。
(2)PLC的CPU则采用顺序逻辑扫描用户程序的运行方式,即如果一个输出线圈或逻辑线圈被接通或断开,该线圈的所有触点(包括其常开或常闭触点)不会立即动作,必须等扫描到该触点时才会动作。为了消除二者之间由于运行方式不同而造成的差异,考虑到继电器控制装置各类触点的动作时间一般在100ms以上,而PLC扫描用户程序的时间一般均小于100ms,因此,PLC采用了-种不同于一般微型计算机的运行方式扫描技术。这样在对于I/O响应要求不高的场合,PLC与继电器控制装置的处理结果上就没有什么区别了。
UNIOP TCM08A 控制板
The SCHNEIDER 140CPU67160 processor module is part of the Modicon Quantum family and is a high-performance controller. With a processor frequency of 266 MHz and 1024 KB of RAM, it can handle large amounts of data and complex control applications. The 140CPU67160 also supports multiple communication interfaces, including Ethernet, Modbus and Modbus Plus, to connect multiple devices and systems. In addition, the 140CPU67160 has an industrial-grade design that allows stable operation over long periods of time in harsh environments.
Digital Signal processors (DSPS) are specialized for signal processing.
Graphics Processing Unit (GPU) processors are primarily designed to render images in real time.
Other specialized units exist for video processing and computer vision. (See: Hardware acceleration.)
Microcontrollers in embedded systems and peripherals.
Systems on a chip typically integrate one or more microprocessors and microcontroller cores with other components such as radio modems for use in smartphones and tablets.
Microprocessors can be selected for different applications based on their word length (a measure of their complexity). The longer word length allows more calculations to be performed per clock cycle, but corresponds to physically larger IC core power consumption with higher standby and operation. 4 -, 8 -, or 12-bit processors are widely integrated into microcontrollers running embedded systems.
Use 16 -, 32 -, or 64-bit processors when the system is processing large amounts of data or requires a more flexible user interface. An 8-OR16-bit processor can be selected instead of a 32-bit processor for system-on-chip or microcontroller applications with low power electronics or a portion of mixed-signal integrated circuits with noise-sensitive on-chip analog electronics such as high-resolution analog-to-digital converters or both. Some say that running a 32-bit algorithm on an 8-bit chip can consume more power because the chip has to execute the software with multiple instructions. However, others say that modern 8-bit chips are always more power-efficient than 32-bit chips when running equivalent software routines.
