    • A safety PLC includes an I/O module to which a safety device for detecting a predetermined condition at any time is connected, a CPU module that executes a safety program for managing the I/O module, and a communication unit that interconnects the I/O module and the CPU module with each other. The CPU module includes: a PIN code memory that stores a PIN code for authenticating that the safety program satisfies a predetermined standard; a PIN code input unit that allows a user to designate the PIN code; a program auto-creating unit that automatically creates the safety program; and a program authentication unit that puts the safety program into an executable condition when the PIN code designated by the user coincides with the PIN code stored in the PIN code memory.
    • 一个安全PLC包括一个I / O模块,一个用于检测任何时间的预定条件的安全装置被连接到该I / O模块,执行用于管理该I / O模块的安全程序的CPU模块,以及一个将I / O模块和CPU模块相互连接。 CPU模块包括:PIN码存储器,其存储用于认证安全程序满足预定标准的PIN码; PIN码输入单元,其允许用户指定PIN码; 自动创建安全程序的程序自动创建单元; 以及程序认证单元,当由用户指定的PIN码与存储在PIN码存储器中的PIN码一致时,将安全程序置于可执行状态。
