CI854AK01 冗余伙伴自动激活

AC 800M控制器与PROFIBUS主模块CI854A相连。什么时候CI854A模块故障或总线通信中断，冗余伙伴自动激活。CI854A对通过CEX总线。线路冗余线路冗余需要冗余传输介质和冗余总线PROFIBUS主设备上的连接。这两种传输介质是电气的在最简单的情况下是电缆，或者在更高要求下是光纤电缆。对于具有两个总线终端的线路冗余、主/从/链路的最佳使用必修的。

主、从或链路检测到线路故障并继续通信在完整的冗余线路上。线路冗余的要求包括对电缆的开路、短路和误差自适应的免疫力，连接器、中继器、媒体转换器和链路。如果PROFIBUS从设备尚未实现冗余PROFIBUS接口，但是，如果对系统可用性的分析表明有必要对于冗余PROFIBUS布线，建议使用冗余链路模块RLM 01。从设备冗余 从属冗余是指至少有冗余链路/网关的情况并且可选地存在冗余I/O模块。如果网关模块出现故障或通信发生干扰，第二网关模块接管任务同样的原理也适用于I/O模块。冗余模块在出现错误的情况下继续记录和/或输出测量值。这个连接的传感器或致动器，包括信号线和命令线，通常仅设置为单个。

The AC 800M controller connects to the main PROFIBUS module CI854A. When the CI854A module fails or the bus communication is interrupted, the redundant partner is automatically activated. The CI854A pair uses the CEX bus. Line redundancy Line redundancy requires the connection of redundant transmission media and redundant bus PROFIBUS master devices. The two transmission media are electrical in the simplest case is cable, or in the higher requirements is fiber optic cable. Required for optimal use of line redundancy, master/slave/link with two bus terminals.

The master, slave, or link detects a line failure and continues communication on a complete redundant line. Requirements for line redundancy include immunity to open, short, and error adaptive cables, connectors, Repeaters, media converters, and links. If the PROFIBUS slave device does not yet implement a redundant PROFIBUS interface, however, if the analysis of system availability indicates that it is necessary to route redundant PROFIBUS, the redundant link module RLM 01 is recommended. Slave device redundancy Slave redundancy is a situation where there are at least redundant links/gateways and optionally redundant I/O modules. If the gateway module fails or interferes with communication, the second gateway module takes over the task. The same principle applies to the I/O module. The redundant module continues to record and/or output measured values in the event of an error. This connected sensor or actuator, including signal and command lines, is usually only set to a single.
