    • PROBLEM TO BE SOLVED: To provide a method and a system for performing operation of an external signal input and output unit used for controlling an automatic machine such as machine tool in a numerical control device without installing a diagnostic circuit on an I/O unit.
      SOLUTION: Each of the host transmitting/receiving blocks of a plurality of I/O units (A1, A2, ...) connected to a CNC reads destination specification data and diagnostic result bit data (0 or 1) each time the host transmitting/receiving block receives a signal packet from the CNC. When the diagnostic result bit indicates the execution of a diagnosis (1), the signal packet contains diagnostic DO data, and the relevant DO signal output terminal is short-circuited to the relevant DI signal input terminal to form a diagnostic loop. The diagnostic packet signal passes through the diagnostic loop, the external signal transmitting/receiving block, and the host transmitting/receiving block and returns to the CNC directly (in the case of the I/O unit A1) or through the host transmitting/receiving block of an adjacent I/O unit closer to the CNC. The CNC analyzes the packet signal to determine whether each of the I/O units is operating normally or not.

    • 要解决的问题:提供一种用于执行用于控制数控装置中的诸如机床的自动机器的外部信号输入和输出单元的操作的方法和系统,而不将诊断电路安装在I / O单位。 解决方案:连接到CNC的多个I / O单元(A1,A2,...)中的每个主机发送/接收块每次都会读取目的地指定数据和诊断结果位数据(0或1) 主机发送/接收块从CNC接收信号包。 当诊断结果位指示执行诊断(1)时,信号包包含诊断DO数据,相关的DO信号输出端子与相关DI信号输入端子短路,形成诊断回路。 诊断分组信号通过诊断回路,外部信号发送/接收块和主机发送/接收块,并直接返回到CNC(在I / O单元A1的情况下)或通过主机发送/接收 靠近CNC的相邻I / O单元的块。 CNC分析分组信号以确定每个I / O单元是否正常运行。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To secure process control as much as possible.
      SOLUTION: At least one process module and at least one security module control at least one process device to be controlled, and a process signal of a process module indifferent to security is mutually and logically connected to a security signal of the security module related to the security of a process. As soon as at least one local security signal of a local security sensor is directly supplied to at least one control output of a local control unit related to the process device, a logical connection operation is bypassed, high-speed state changing is performed in the process device to be controlled connected to the control output, a high-speed switching path includes a high-speed switching function, the high-speed switching function evaluates both a result of the logical connection operation and the local security signal, the high-speed state changing in the process device to be controlled is changed again, and reversion is made again, especially when shared evaluation causes a predetermined result.
