霍尼韦尔 51305072-300 CLCN-B 数字输入输出模块 通信冗余系统

产品描述

I0卡是一个工业级的远程Bai采集控制模块，提供开关量采集、跟踪智电器输出、高频计数器等无源节点功能。该系列多个模块可用于总线组网，使lO点可灵活扩展。该模块可以通过远程命令进行控制。

模块采用工业组件，10-30vdc宽电压输入，能在-30C℃~60℃范围内正常工作，采用RS232、RS485通讯方式与上位机交互。IO卡通信协议是工业标准的MODBUS-RTU协议，MODBUS协议定义了控制器可以识别和使用的消息结构，无论通过何种网络进行通信，都规定了消息域的模式和内容的通用格式，描述控制器请求访问其他设备、响应来自其他设备的请求以及检测和记录错误信息的过程。

通过该协议，控制器之间以及控制器与其他设备之间通过网络完成信息和数据的交换和传输，从而使PLC、RTU、SCADA系统、不同公司和制造商的DCS或与Modbus协议兼容的三方设备连接到一个工业现场建立各种复杂的网络监控系统。

Product description

The I0 card is an industrial-grade remote Bai acquisition and control module, which provides passive node functions such as switching data acquisition, tracking of intelligent electrical output, and high-frequency counter. Several modules of this series can be used for bus networking, so that lO points can be flexibly expanded. The module can be controlled by remote commands.

The module uses industrial components, 10-30vdc wide voltage input, can work normally in the range of -30C ~60℃, RS232, RS485 communication mode to interact with the host computer. IO card communication protocol is the industry standard MODbus-RTU protocol. MODBUS protocol defines the message structure that the controller can recognize and use. No matter what kind of network is used for communication, the mode of the message domain and the general format of the content are specified. Describes the process by which controllers request access to other devices, respond to requests from other devices, and detect and log error messages.

Through this protocol, the exchange and transmission of information and data between the controller and the controller and other devices through the network, so that PLC, RTU, SCADA system, DCS of different companies and manufacturers or third-party devices compatible with Modbus protocol are connected to an industrial site to establish a variety of complex network monitoring systems.
