用于工业控制器的输入模块
摘要：
公开了一种用于工业控制器的输入模块。根据一个实施例的输入模块包括：多个输入端子，其被配置成从远程装置接收输入信号；存储器装置，其被配置成存储多个配置参数，其中，配置参数将输入端子中的第一部分定义为计数器端子，并且将输入端子中的第二部分定义为除计数器端子之外的端子；计数器逻辑电路；以及另外的逻辑电路，其被配置成从输入端子的第二部分接收输入信号。计数器逻辑电路被配置成：读取配置参数以识别每个计数器端子；从输入端子的第一部分接收输入信号；检测来自输入端子的第一部分的每个输入信号的状态转变；以及将转变累积值存储在存储器装置中。
摘要（英）：

An input module for an industrial controller is disclosed. The input module according to one embodiment includes a plurality of input terminals configured to receive an input signal from a remote device, a memory device configured to store a plurality of configuration parameters, wherein the configuration parameters define a first part of the input terminals as a counter terminal, and define a second part of the input terminals as terminals except the counter terminal; a counter logic circuit; and another logic circuit configured to receive the input signal from the second part of the input terminals. The counter logic circuit is configured to read the configuration parameters so as to identify each counter terminal, receive the input signal from the first part of the input terminals, detect the state change of each input signal from the first part of the input terminals, and store a change accumulated value in the memory device.
