ProSoft Technology以其“工业无线”系列解决方案而 事实上，该公司的根源在于自动化应用的“工业协议”解决方案：ProSoft Technology的 个产品系列（始于1988年！）是罗克韦尔自动化控制器（安装在控制器机架内的模块）的通信接口。由于ProSoft Technology在为该系列控制器的用户提供紧密集成的网络接口解决方案方面的长期经验，通信 也能够为新的Logix-XT（eXTreme环境）产品系列提供接口解决方案。 罗克韦尔自动化公司的这一Logix-XT新平台帮助自动化 降低安装和维护 ，减少了在 环境中对控制器机柜额外加热和冷却设备的需求。

4301-MBP-DFCM几余，指重复配置系统的一些部件，当系统发生故障时，几余配置的部件介入并承担故障部件的工作，由此减少系统的故障时间。模块化几余是指将系统构成上采用复式模块化结构[1]，当一部件出现故障时，可自动或人工重构结构，由另一部件替代故障部件工作，系统降级使用，除故障部件外，其余部分仍保持正常运行。4301-MBP-DFCM几余技术就是增加多于的设备，以保证系统可靠地工作。模块化几余是指将系统分层不同的功能模块，并采用几余技术，当系统某个功能模块出现故障时，用几余功能模块结构代替出故的模块，使系统正常工作。模块化几余是一种动态几余技术，属于硬件几余范畴。动态几余是指采用标准模块配置工作，一旦检测与诊断出故障发生的位置,系统能进行重组或恢复，并继续正常运行。

4301-MBP-DFCM以检测或屏蔽故障为目的而添加一定硬件设备的方法。常见的方法如下硬件容错方法之一是硬件堆积几余，在物理级可通过元件的重复而获得(如相同元件的串、并联，四倍元件等)。另一硬件容错的方法叫待命储备几余。该系统中共有M+1个模块，其中只有一块处于工作状态，其余M块都处于待命接替状态。-日工作模块出了故喧，立刻切换到一个待命模块，当换上的储备模块发生故障时，又切换到另一诸备模块，直到资源枯竭，显然，这种系统必须具有检错和切换的装置

4301-MBP-DFCM混合几余系统是堆积几余和待命储备几余的结合应用。当堆积几余中有一个模块发生故障时，立刻将其切除并代之以无故障待命模块。这种方法可达到较高的可靠性。

ProSoft Technology is famous for its "industrial wireless" series of solutions. In fact, the company's roots lie in the "industrial protocol" solutions for automation applications: ProSoft Technology's 10 product series (started in 1988! ) is the communication interface of Rockwell Automation Controller (a module installed in the controller rack). Because of ProSoft Technology's long-term experience in providing tightly integrated network interface solutions for users of this series of controllers, communication can also provide interface solutions for the new Logix-XT(eXTreme Environment) product series. Rockwell Automation's new Logix-XT platform helps automation reduce installation and maintenance, and reduces the need for additional heating and cooling equipment for the controller cabinet in the environment.

4301-MBP-DFCM redundancy refers to the repeated configuration of some components of the system. When the system fails, the redundant components intervene and undertake the work of the failed components, thus reducing the failure time of the system. Modular redundancy means that the system adopts a compound modular structure [1]. When one component fails, the structure can be reconstructed automatically or manually, and another component replaces the failed component to work, so the system is degraded and used. Except for the failed component, the rest parts still maintain normal operation. The redundant technology of 4301-MBP-DFCM is to add more equipment to ensure the system to work reliably. Modularization redundancy means that the system is divided into different functional modules, and redundancy technology is adopted. When a functional module of the system fails, the failed module is replaced by a redundant functional module structure to make the system work normally. Modular redundancy is a dynamic redundancy technology, which belongs to the category of hardware redundancy. Dynamic redundancy refers to working with standard module configuration. Once the fault location is detected and diagnosed, the system can be reorganized or restored and continue to operate normally.

4301-MBP-DFCM is a method of adding certain hardware equipment for the purpose of detecting or shielding faults. The common methods are as follows: one of the hardware fault-tolerant methods is to accumulate more than one hardware, which can be obtained by repeating components at the physical level (such as serial, parallel, quadruple components of the same component, etc.). Another method of hardware fault tolerance is called standby redundancy. There are M+1 modules in the system, only one of which is in working state, and the other m modules are in standby replacement state. -If the daily work module goes wrong, switch to a standby module immediately, and when the replaced reserve module goes wrong, switch to another standby module until the resources are exhausted. Obviously, this system must have error detection and switching devices.

The 4301-MBP-DFCM hybrid redundancy system is a combination of stacking redundancy and standby redundancy. When one module in the stack breaks down, it will be removed immediately and replaced by a trouble-free standby module. This method can achieve high reliability.
