0100-20100 AMAT 美国应用材料 半导体行业应用

0100-20100应用AMAT系列半导体行业设备数控板卡进口供应控制下，电路设计或顺序的任何更改只需重新输入逻辑即可。在 PLC 中纠正错误的时间非常短，而且效益高。节省空间： 我们可以生成越来越多的触点、线圈、定时器、计数器、序列等，在一个 PLC 中可以有数千个触点定时器和计数器。： 可编程逻辑控制器的价格从几百到几千不等。测试： 可编程逻辑控制器程序可在实验室中进行测试和评估。可以对程序进行测试、验证和修正，从而节省宝贵的时间。更容易排除故障： 电路故障排除非常快速、轻松和简单。

PLC 的缺点是

- 难以发现错误，需要熟练的操作人员。

- 一旦出现问题，滞留时间不确定，通常较长。

- 接线工作量大

- 更改或更换困难

PLC 的类型：

PLC 可集成为单个或模块单元。PLC 的类型有

- 集成或紧凑型 PLC- 模块式 PLC小型 PLC中型 PLC大型 PLC

它是一种微型 PLC，设计紧凑，可安装或放置在需要控制的设备旁边。它可用于替代硬接线继电器逻辑、计数器、定时器等。它使用逻辑指令表或继电器语言作为编程语言中型 PLC 是工业中常用的 PLC，因为它允许在系统的黑色平面上安装插件模块。通过添加额外的 I/O 卡，可提供通信模块设施和输入/输出。

0100-20100 Under the import supply control of AMAT series semiconductor industry equipment CNC board, any change in circuit design or sequence can be simply re-entered logic. The time to correct errors in PLC is very short and the efficiency is high. Space saving: We can generate more and more contacts, coils, timers, counters, sequences, etc. There can be thousands of contact timers and counters in one PLC. Programmable logic controllers range in price from several hundred to several thousand. Testing: Programmable logic controller programs can be tested and evaluated in the laboratory. Programs can be tested, validated, and corrected, saving valuable time. Easier troubleshooting: Circuit troubleshooting is fast, easy and simple.

The disadvantages of PLC are

- Difficult to detect errors and requires skilled operators.

- Once there is a problem, the retention time is uncertain and usually long.

- A lot of wiring work

- Difficult to change or replace

Type of PLC:

PLCS can be integrated as single or modular units. The types of PLC are

- Integrated or compact PLC- Modular PLC Small PLC Medium PLC Large PLC

It is a miniature PLC with a compact design that can be installed or placed next to the equipment that needs to be controlled. It can be used instead of hardwired relay logic, counters, timers, etc. It uses a logic instruction table or relay language as a programming language Medium-sized PLCS are commonly used in industry because it allows plug-in modules to be installed on the black plane of the system. Communication module facilities and input/output can be provided by adding additional I/O cards.
