AB 1756-CN2R/B 控制网通信模块

使用1756-CN2 ControlLogix ControlNet系列B模块，如果  多余的媒体是不必要的。 应用程序需要冗余  介质必须使用1756-CN2R模块。  

理解独立控制和冗余控制  您可以使用1756-CN2R系列B模块独立或  冗余控制。 

对于独立控制，只有一组模块是  必需的。 对于冗余控制，两个ControlLogix机箱是  用称为伙伴的完全相同的模块对填充。 底盘  执行主动控制的被称为主底盘和  机箱中的模块称为主模块。 

另一个底盘  称为次机箱，机箱中的模块是  被称为辅助模块。  这些安装说明讨论了独立安装和冗余安装  控制; 仔细阅读它们，区分程序和  每种控制类型的需求。  如果使用冗余控制，则必须选择相同的控制网  每组伙伴模块(主要和  二次)。 还必须将合作伙伴模块放在相同的位置  对应的插槽在各自的冗余控制机箱 

Use the 1756-CN2 ControlLogix ControlNet Series B module if excess media is not necessary. Applications requiring redundant media must use the 1756-CN2R module.

Understanding Independent and redundant control You can use the 1756-CN2R Series B module for independent or redundant control.

For independent control, only one set of modules is required. For redundant control, the two ControlLogix enclosures are filled with identical pairs of modules called partners. The chassis that performs active control is called the main chassis and the module in the chassis is called the main module.

The other chassis is called a sub-chassis, and the modules in the chassis are called auxiliary modules. These installation instructions discuss independent and redundant installation controls; Read them carefully, distinguishing between the program and the requirements of each control type. If redundant control is used, the same control network must be selected for each set of partner modules (primary and secondary). It is also necessary to place the partner modules in the same position as the corresponding slots in the respective redundant control chassis
