本发明涉及一种安全系统的菊花链。一种系统包括第一计算机、第二计算机和活跃计算机系统确定模块。第一计算机从第二计算机接收表示第二计算机中的故障的第二计算机正常信号并且生成表示第一计算机和/或第二计算机中的故障的第一计算机系统正常信号。活跃计算机系统确定模块接收第一计算机系统正常信号并且基于第一计算机系统正常信号生成待机信号。第二计算机接收待机信号并基于待机信号禁用其输出端口中的一个或多个。
摘要（英）：

The invention relates to a daisy-chain of safety systems. The system includes a first computer, a second computer, and an active computer system determining module. The first computer receives a second computer health signal from the second computer indicating a fault in the second computer and generates a first computer system health signal indicating a fault in the first and/or second computer.The active computer system determining module receives the first computer system health signal and generates a standby signal based on the first computer system health signal. The second computer receives the standby signal and disables one or more of its output ports based on the standby signal.
