SPAD346C EPROM (Erasable Progranmable Read Only Memory)。这是一种可擦除的只读存储器在断电情况下存储器内的所有内容保持不变(在紫外线连续照射下可擦除存储器内容)) EPROM (Electrical Erasable Programmable Read Only Memory)。这是一种电可擦
除的只读存储器。使用编程器就能很容易地对其所存储的内容进行修改。
(2) PLC存储空间的分配。虽然各种PLC的CPU的*寻址空间各不相同，但是根
据PLC的工作原理其存储空间一般包括以下三个区域:系统程序存储区、系统RAM存储
区(包括I/O映像区和系统软设备等)、用户程序存储区。
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。
本次实训是借助MCGS组态软件平台来完成组态监控系统人机界面制作和程序的设计的。MCGS(Monitor and Control Generated System, 通用监控系统）组态软件是北京昆仑通态软件公司研发的基于Window平台的，用于快速构造和生成上位机监控系统的组态软件系统。通过对现场数据的采集处理，以动画显示、报警处理、流程控制、报表输出等和多种方式向用户提供解决实际工程问题的开发平台。
由于是国人开发的软件，所以它是全中文的，很适合我们使用，还有它可提供近百种绘图工具和基本图符，快速构造图形界面，此外还提供上千个精美的图库元件及渐进色等多种
动画方式可以快速的构建精美的动画，它还支持温控曲、计划曲线、时实曲线、历史曲线、XY等多种工控曲线。之使用MCGS软件可以较快速的完成一个运行稳定、功能成熟、维护量小并且具备*水准的计算机监控控制系统的开发工作。下面我来介绍在使用MCGS组态软件来完成任务的详细过程及遇到的问题和解决的办法。
All contents in the memory remain unchanged when the device is powered off (the memory contents can be erased under continuous ultraviolet irradiation).
3) EPROM (Electrical Erasable Programmable Read Only Memory)。 This is an electrically erasable
Read only memory except. The stored contents can be easily modified by using the programmer.
(2) Allocation of PLC storage space. Although the maximum address space of the CPUs of various PLCs is different
According to the working principle of PLC, its storage space generally includes the following three areas: system program storage area and system RAM storage
Area (including I / O image area and system software equipment), user program storage area.
1) System program storage area. A system program corresponding to the computer operating system is stored in the system program storage area,
Including monitoring program, management program, command interpretation program, function subprogram, system diagnosis subprogram, etc. By the manufacturer
It is solidified in EPROM and cannot be directly accessed by the user. It determines the performance of the PLC together with the hardware.
2) System RAM storage area. System RAM storage area includes I / O image area and various soft devices, such as logic
Coils, data registers, timers, counters, index registers, accumulators and other memories. Configuration control technology is a kind of computer control technology. It is to use the computer to monitor certain equipment to make it work according to the control requirements. The computer configuration monitoring system composed of configuration control technology is mainly composed of controlled
This training is
Because it is a software developed by Chinese people, it is all Chinese and very suitable for our use. In addition, it can provide nearly 100 kinds of drawing tools and basic symbols, quickly construct graphical interfaces, and also provide thousands of exquisite library elements and progressive colors
The animation mode can quickly build beautiful animation, and it also supports temperature control curve, plan curve, time real curve, history curve, XY and other industrial control curves. In short, MCGS software can quickly complete the development of a computer monitoring and control system with stable operation, mature function, small maintenance and professional level. Next, I will introduce the detailed process of using MCGS configuration software to complete the task, the problems encountered and the solutions.
