PFEA111-20  输入寄存器反映输入信号状态，输出点反映输出锁存器状态

可编程逻辑控制器（PLC）模块是PLC系统的重要组成部分，PFEA111-20 主要通过各种输入/输出模块与外界联系。

PLC的对外功能，主要是通过各种输入/输出模块与外界联系的，按I/O点数确定模块规格及数量，I/O模块可多可少，但其最大数受CPU所能管理的基本配置的能力，即受最大的底板或机架槽数限制。

输入单元是用来链接截取输入组件的信号动作并透过内部总线将数据送进存储器由CPU处理驱动程序指令部分。PFEA111-20 而输出模块在工业环境中用来控制制动器、气阀及马达等。

此外，PLC模块集成了PLC的I/O电路，其输入寄存器反映输入信号状态，输出点反映输出锁存器状态。

可编程逻辑控制器模块（Programmable Logic Controller Module）是一种PFEA111-20 用于工业控制的数字电子设备。它通常由微处理器、存储器、输入/输出接口和编程接口组成，可以通过编程实现各种逻辑控制功能，例如顺序控制、定时控制、计数控制、模拟量控制等。

可编程逻辑控制器模块通常用于自动化生产线、机器人控制、工业过程控制、电力系统控制等领域。它们可以通过网络连接到上位计算机或其他设备，实现集中控制和监测。

可编程逻辑控制器模块的优点包括可靠性高、易于编程、灵活性强、可扩展性好等。它们可以大大提高工业生产的效率和质量，减少人力成本和误差。

Programmable logic controller (PLC) module is an important part of PLC system, PFEA111-20 mainly through a variety of input/output modules to contact the outside world.

PLC external functions, mainly through a variety of input/output modules to contact the outside world, according to I/O points to determine the module specifications and quantity, I/O modules can be more or less, but its maximum number by the CPU can manage the basic configuration of the ability, that is, by the maximum number of chassis or rack slots limited.

The input unit is used to link the signal action of the input component and send data to the memory through the internal bus to be processed by the CPU driver instruction part. The PFEA111-20 output module is used to control brakes, valves and motors in industrial environments.

In addition, the PLC module integrates the PLC I/O circuit, the input register reflects the input signal state, the output point reflects the output latch state.

The Programmable Logic Controller Module is a PFEA111-20 digital electronic device for industrial control. It is usually composed of a microprocessor, memory, input/output interface and programming interface, and can be programmed to achieve a variety of logic control functions, such as sequence control, timing control, counting control, analog control, etc.

Programmable logic controller module is usually used in automatic production line, robot control, industrial process control, power system control and other fields. They can be connected to the upper computer or other devices through the network to achieve centralized control and monitoring.

The advantages of programmable logic controller module include high reliability, easy programming, strong flexibility and good expansibility. They can greatly improve the efficiency and quality of industrial production and reduce labor costs and errors.
