【产品详情】

MODBUS TCP是一个开放的行业标准，由于其易用性而得到广泛传播。它是一种请求响应协议，提供由功能代码指定的服务。

MODBUS TCP将MODBUS RTU与标准以太网和通用网络标准TCP相结合。它是一种应用层消息传递协议，位于 OSI 模型的第 7 级。CI867A/TP867 用于使用 Modbus TCP 协议的 AC 800M 控制器和外部以太网设备之间的连接。

CI867扩展单元包含CEX-Bus逻辑、通信单元和DC/DC转换器，通过CEX-Bus从+24 V电源提供适当的电压。以太网电缆必须通过以太网交换机连接到主网络。

CI867A 模块仅适用于 System 800xA 6.0.3.3、6.1.1。和后续版本。

特点和优势

CI867A可以设置为冗余，并支持热插拔。

CI867A是单通道以太网单元;Ch1 支持速度为 100 Mbps 的全双工。支持主功能和从功能。

每个CI867A最多可以使用70个从站和8个主站。

【英文介绍】

MODBUS TCP is an open industry standard that has spread widely due to its ease of use. It is a request-response protocol that provides services specified by functional code.

MODBUS TCP combines MODBUS RTU with standard Ethernet and the common networking standard TCP. It is an application-layer messaging protocol that is located at level 7 of the OSI model. The CI867A/TP867 is used to connect AC 800M controllers using the Modbus TCP protocol to external Ethernet devices.

The CI867 expansion unit contains the CEX-Bus logic, communication unit, and DC/DC converter, providing the appropriate voltage from a +24 V power supply via the CEX-Bus. Ethernet cables must be connected to the main network through an Ethernet switch.

The CI867A module applies only to System 800xA 6.0.3.3 and 6.1.1. And later versions.

Characteristics and advantages

The CI867A can be configured as redundant and supports hot swap.

CI867A is a single channel Ethernet unit; The Ch1 supports full duplex with a speed of 100 Mbps. Supports master and slave functions.

Each CI867A can use up to 70 slave stations and 8 master stations.
