MVI56-MCM Modbus 主站/从站通信模块

【产品详情】

使用 MVI56E 增强型 Modbus 主站/从站通信模块，罗克韦尔自动化® ControlLogix® 处理器可以轻松连接采用 RTU/ASCII 串行通信协议的设备。

MVI56E-MCM 和 MVI56E-MCMXT 作为 ControlLogix 背板上的输入/输出模块，使得 Modbus 数据对于处理器来说就像是 I/O 数据。与处理器进行的数据传输与 Modbus 网络上的通信异步。模块具备两个可独立配置的串行端口，可运行在相同或不同的 Modbus 网络中。每个端口都可配置为 Modbus 主站或从站，共享同一个由用户控制的 10000 字数据库。

两个模块在功能上完全相同。MVI56E-MCM 用于标准过程应用项目。MVI56E-MCMXT 用于 Logix-XT™ 控制平台，可工作在极端环境中。它能耐受更高的工作温度，并且具备在严苛或腐蚀条件下提供保护的敷形涂层。

MVI56-MCM Modbus 主站/从站通信模块

【英文介绍】

With the MVI56E Enhanced Modbus master/Slave communication module, Rockwell Automation ® ControlLogix® processors can easily connect devices using the RTU/ASCII serial communication protocol.

The MVI56E-MCM and MVI56E-MCMXT act as input/output modules on the ControlLogix backplane, making Modbus data look like I/O data to the processor. The data transfer with the processor is asynchronous with the communication on the Modbus network. The module has two independently configurable serial ports that can operate in the same or different Modbus networks. Each port can be configured as a Modbus master or slave, sharing the same user-controlled 10,000-word database.

The two modules are functionally identical. The MVI56E-MCM is used for standard process application projects. The MVI56E-MCMXT is used in the Logix-XT™ control platform to operate in extreme environments. It withstands higher operating temperatures and has a form coating that provides protection under harsh or corrosive conditions.
