特点和优点

通过以太网连接PROFINET IO设备

CI871 通信接口（communication interface）是指中央处理器和标准通信子系统之间的接口。在计算机领域中，通信接口用于实现计算机与外部设备之间的数据传输和信息交换。常见的通信接口包括串口、并口、USB接口、以太网接口等。

串口（serial port）是一种常见的通信接口，采用串行通信方式进行数据传输。串口通信时，数据一位一位地顺序传输，每一位数据占据一个固定的时间长度，适用于短距离通信，如计算机与外部设备或不同计算机之间传输数据。常见的串口包括RS-232、RS-485、USB等。

并口（parallel port）也是一种常见的通信接口，采用并行通信方式进行数据传输。并口通信时，多位数据同时传输，提高了数据传输速率，但传输距离较短，适用于短距离、高速率的通信场合。常见的并口为打印机接口。

USB接口（Universal Serial Bus）是一种常用的通信接口，采用串行通信方式进行数据传输。USB接口具有即插即用、支持热插拔、高速数据传输等特点，广泛应用于各种设备之间的数据传输，如手机、平板电脑、数码相机等。

以太网接口（Ethernet Interface）是一种网络通信接口，采用以太网协议进行数据传输。以太网接口可以实现计算机与局域网、互联网之间的数据传输和信息交换，具有传输速率高、传输距离远等特点。常见的以太网接口为RJ-45接口。

总之，CI871 通信接口是实现计算机与外部设备之间数据传输和信息交换的重要手段，不同的通信接口适用于不同的应用场合。随着技术的发展，新的通信协议和接口标准也不断涌现，为人们提供了更多的选择和更好的通信体验。

The CI871A is an AC 800M communication interface that connects to PROFINET IO devices over Ethernet. The TP867 Baseplate has two RJ45 Ethernet connectors, but the PROFINET IO connection only uses a CH1 connector that supports 100Mbps. Ethernet cables must be connected to the PROFINET IO network through an Ethernet switch.

The CI871 expansion unit contains the CEX-Bus logic, communication unit, and DC/DC converter that provides the required voltage from a + 24v power supply via the CEX-Bus.

The CI871A module is only applicable to System 800xA 6.0.3.3, 6.1.1, and later versions

Features and advantages

Connect the PROFINET IO device via Ethernet

CI871 communication interface refers to the interface between the central processing unit (CPU) and the standard communication subsystem. In the computer field, communication interfaces are used to realize data transmission and information exchange between computers and external devices. Common communication interfaces include serial ports, parallel ports, USB ports, and Ethernet ports.

serial port is a common communication interface that uses serial communication for data transmission. In serial communication, data is sequentially transmitted bit by bit, and each bit of data occupies a fixed length of time, which is suitable for short-distance communication, such as the transmission of data between computers and external devices or between different computers. Common serial ports include RS-232, RS-485, and USB.

parallel port is also a common communication interface that uses parallel communication for data transmission. In parallel port communication, multi-bit data is transmitted at the same time, which improves the data transmission rate, but the transmission distance is short, and it is suitable for short-distance and high-rate communication occasions. The common parallel interface is the printer interface.

Universal Serial Bus (USB) is a common communication interface that uses serial communication for data transmission. USB interface has the characteristics of plug and play, support hot swap, high-speed data transmission, etc., widely used in data transmission between various devices, such as mobile phones, tablet computers, digital cameras, etc.

An Ethernet Interface is a network communication interface that uses the Ethernet protocol for data transmission. Ethernet interface can realize data transmission and information exchange between computer, local area network and Internet, and has the characteristics of high transmission rate and long transmission distance. The common Ethernet interface is the RJ-45 interface.

In short, CI871 communication interface is an important means to realize data transmission and information exchange between computers and external devices, and different communication interfaces are suitable for different applications. With the development of technology, new communication protocols and interface standards continue to emerge, providing people with more choices and better communication experience.
