1756-MVI 多供应商接口 （MVI） 模块

【产品详情】

1756-MVI 的散热为 21.2 BTU 小时，其隔离电压为 50 伏连续电压。1756-MVI 模块附带 6 个组件：1756-MVI 模块本身、3 根串行适配器电缆、1 本安装说明小册子和 1 张 CD-ROM（仅适用于 1756-MVID）。该模块具有与BIOS和DOS兼容的嵌入式操作系统。如果安装正常进行，屏幕上应显示启动消息，但如果未显示任何消息，请检查安装跳线是否正确安装以及电缆连接是否正确。

1756-MVI 是一个多供应商接口 （MVI） 模块。与 Allen-Bradley ControlLogix 系列中的所有模块一样，1756-MVI 易于安装，可用于 Allen-Bradley ControlLogix 机箱上的任何插槽。它没有外壳。模块前面板上的 LED 用于指示通道和模块的状态。这有助于对 PLC 进行故障排除。

1756-MVI 的前面板下方有 3 个 DJ% 通信端口，用于连接 ControlLogix 系统和外部设备。通信协议由位于 1756-MVI 侧面的跳线设置。更改跳线后，MVI 可通过 RS-232、RS-422 或 RS-485 通信端口与其他机器进行通信。

【英文介绍】

The 1756-MVI has a heat dissipation of 21.2 BTU hours and an isolation voltage of 50 volts continuous. The 1756-MVI module comes with 6 components: the 1756-MVI module itself, 3 serial adapter cables, 1 installation instructions booklet, and 1 CD-ROM (for 1756-MVID only). The module has an embedded operating system compatible with BIOS and DOS. If the installation is progressing normally, a startup message should be displayed on the screen, but if no message is displayed, check that the installation jumper is installed correctly and that the cable is connected correctly.

The 1756-MVI is a multi-vendor interface (MVI) module. Like all modules in the Allen-Bradley ControlLogix series, the 1756-MVI is easy to install and can be used in any slot on the Allen-Bradley ControlLogix chassis. It has no shell. Leds on the front panel of the module are used to indicate the status of the channel and module. This helps troubleshoot the PLC.

The 1756-MVI has three DJ% communication ports under the front panel for connecting the ControlLogix system to external devices. The communication protocol is set by a jumper located on the side of 1756-MVI. After changing the jumper, the MVI can communicate with other machines via RS-232, RS-422, or RS-485 communication ports.
