    • An input termination board for use with an industrial controller in a safety system is disclosed herein. The industrial controller may be populated with standard analog input modules according to the requirements of the application. The termination board may selectively receive a single analog input signal from a remote device and transmit the signal to corresponding channels on two analog input modules or, alternately, receive two analog input signals and transmit each signal to one of the two corresponding channels. In addition, a program executing on the controller of the safety module monitors and tests each of the analog input channels on the input modules, verifying proper operation of the modules. If the program detects a fault in either input module, the safety system may alternately shut down according to a fail-safe procedure or continue operating under a fault-tolerant mode of operation.
    • 本文公开了一种与安全系统中的工业控制器一起使用的输入端接板。 工业控制器可以根据应用的要求填充标准的模拟量输入模块。 终端板可以选择性地从远程设备接收单个模拟输入信号,并将信号发送到两个模拟输入模块上的相应通道,或者交替地接收两个模拟输入信号,并将每个信号发送到两个对应的通道之一。 此外,在安全模块的控制器上执行的程序监视和测试输入模块上的每个模拟输入通道,验证模块的正确操作。 如果程序检测到任一输入模块中的故障,则安全系统可以根据故障安全程序交替关闭或在容错操作模式下继续运行。
