FPD-375.16PC24 KNIEL 控制器  采用紧凑型设计

型号：FPD-375.16PC24.4

品牌：KNIEL

FPD-375.16PC24是一种安全相关控制器，其作用是扩展I/O级别，不能单独运行任何用户程序。

FPD-375.16PC24采用紧凑型设计，具有丰富的输入输出端口、多样化的信号处理电路、控制逻辑电路等组成，可以接收来自控制系统的数字信号，并将其转换为工业现场的执行器或传感器能够识别的信号，同时也可以将工业现场的传感器或执行器的信号转换为数字信号传输给控制系统。FPD-375.16PC24具有高精度、高可靠性、高抗干扰性等特点，被广泛应用于各种工业自动化控制系统中。

I/O（Input/Output）是指输入/输出，即数据或信号的输入和输出。在计算机领域，I/O指的是与计算机交互的过程，包括读取、写入、处理数据等操作。I/O设备是指能够进行输入输出操作的各种设备，例如键盘、鼠标、显示器、打印机、扫描仪等。在现代计算机中，I/O通常是通过总线、接口或网络等与计算机系统连接的。

FPD 375.16PC/24.4 KNIELPLC、DCS、PC的交叉点:

在现有技术的发展过程中，因为IC技术、通信技术、软件技术的高速发展。PLC、DCS、IPC在近几年出现了相当多的交叉和重复，基本上变成了PLC看起来像DCS,而IPC改头换面之后与大多数的软PLC并无二样，也采用模块化结构，也使用IEC61131-3的五种语言，在使用上面比大多数的PLC加容易加偏软件。

这些年经常见到一些朋友问到底DCS与PLC的区别是什么，IPC+软逻辑之后是不是PLC?

这个问题真是一个很模糊的问题，因为差别实在是太小了。我曾经研发了五年的DCS又研发了四年的PLC，其中多次使用IPC+软逻辑开发过PLC产品，所以从我!

]做研

发的定义来分辨这几种产品吧。

DCS原来设计主要是为顺序控制开发的，大多数执行是定时扫描方式，循环的速度要求不高，多数在50ms~1秒以上可以设，但DCS应用的场合主要是电厂的主控造纸等，这些场合是一些比较复杂的模型，需要较强的模拟量运算能力，同时大多数DCS都针对不同的开发不同的功能块，使用户在使用时不需要自己用PID之类

的算

法做控制，而是抽象到了模型或者回路这—层。

另外DC的用途点数通常比较多，很多大系统加上中间点可以达到20万点以上，硬IO点数也在数万点之多，如果用一台控制器当然是很困难的，所以大多数DCS在基于网络的多DPU协同工作方面有很强的能力。

Pfd-375.16 The PC24 is a safety-related controller whose role is to extend the I/O level and cannot run any user programs alone.

FPD-375.16PC24 adopts compact design, with a wealth of input and output ports, a variety of signal processing circuits, control logic circuits, etc., can receive digital signals from the control system, and convert them into signals that can be recognized by actuators or sensors in industrial sites. At the same time, it can also convert the signal of the sensor or the actuator in the industrial field into a digital signal for transmission to the control system. Pfd-375.16 PC24 has the characteristics of high precision, high reliability and high anti-interference, and is widely used in various industrial automation control systems.

I/O (Input/Output) refers to input/output, that is, the input and output of data or signals. In the computer field, I/O refers to the process of interacting with a computer, including operations such as reading, writing, and processing data. I/O devices refer to various devices capable of input and output operations, such as keyboards, mice, monitors, printers, scanners, etc. In modern computers, I/O is usually connected to the computer system through a bus, interface, or network.

FPD 375.16PC/24.4 Intersection of KNIELPLC, DCS and PC:

In the process of the development of existing technology, because of the rapid development of IC technology, communication technology and software technology. PLC, DCS, IPC in recent years there has been quite a lot of crossover and repetition, basically becoming a PLC looks like DCS, and IPC after a makeover with most of the soft PLC and no two, also using modular structure, also using IEC61131-3 five languages, in the use of the above than most PLC plus easy to add software.

These years often see some friends ask what is the difference between DCS and PLC, IPC+ soft logic is not PLC?

This is a really vague question because the difference is so small. I have developed DCS for five years and developed PLC for four years, of which IPC+ soft logic has been used many times to develop PLC products, so from me!

] do research

Hair definition to distinguish these products.

The original design of DCS is mainly developed for sequence control, most of the execution is timed scanning mode, the speed of the cycle is not high, most of the 50ms~1 second or more can be set, but the DCS application occasions are mainly the main control of the power plant papermaking, etc., these occasions are some more complex models, require strong analog computing power, At the same time, most DCS have different functional blocks for different development, so that users do not need to use PID and so on

Calculation of

Method to do control, but abstract to the model or loop this layer.

In addition, the use of DC points is usually more, many large systems with intermediate points can reach more than 200,000 points, hard IO points are also tens of thousands of points, if you use a controller is of course very difficult, so most DCS in the network-based multi-DPU collaborative work has a strong ability.
