XBTGK5330施耐德触摸屏电气变压器处理单元(CPU)处理单元

检查电源、存储器、VO以及警戒定时器的状态，
并能诊断用户程序中的语法错误:当PLC投入运行时，首先它以扫描的方式接收现场各输
入装置的状态和数据，并分别存入IO映像区，然后从用户程序存储器中逐条读取用户程
序，经过命令解释后，按指令的规定将逻辑或算术运算的结果送入Vo映像区或数据寄存
器内。等所有的用户程序执行完毕之后，后将1/O映像区的各输出状态或输出寄存器内
的数据传送到相应的输出装置，如此循环运行，直到停止运行为止。1)系统程序存储区。在系统程序存储区中存放着相当于计算机操作系统的系统程序，
包括监控程序、管理程序、命令解释程序、功能子程序、系统诊断子程序等。由制造厂商
将其固化在EPROM中，用户不能直接存取。它和硬件一起决定了该PLC的性能。
2)系统RAM存储区。系统RAM存储区包括I/O映像区以及各类软设备，如:逻辑
线圈、数据寄存器、计时器、计数器、变址寄存器、累加器等存储器。组态控制技术属于一种计算机控制技术。它是利用计算机监控某种设备使其按照控制要求工作。利用组态控制技术构成的计算机组态监控系统主要由被控对象、传感器、I/O接口、计算机及执行机构等部分组成。

Check the status of the power supply, memory, VO, and alert timer,
And can diagnose syntax errors in user programs: when the PLC is put into operation, it first receives various on-site inputs in a scanning manner
Enter the status and data of the device, store them separately in the IO image area, and then read the user program one by one from the user program memory
After command interpretation, the result of logical or arithmetic operations is sent to the Vo image area or data storage according to the instructions
Inside the device. After all user programs have been executed, the output states or output registers of the 1/O image area will be updated
The data is transmitted to the corresponding output device and runs in a loop until it stops running. 1) System program storage area. In the system program storage area, there are system programs that are equivalent to the computer operating system,
Including monitoring programs, management programs, command interpreter programs, functional subroutines, system diagnostic subroutines, etc. By the manufacturer
Fix it in EPROM so that users cannot access it directly. It, together with the hardware, determines the performance of the PLC.
2) System RAM storage area. The system RAM storage area includes the I/O image area and various software devices, such as logic
Memory such as coils, data registers, timers, counters, index registers, accumulators, etc. Configuration control technology belongs to a type of computer control technology. It is the use of computers to monitor a certain device and make it work according to control requirements. The computer configuration monitoring system composed of configuration control technology mainly consists of controlled objects, sensors, I/O interfaces, computers, and execution mechanisms.
