    • PROBLEM TO BE SOLVED: To provide a safety output device for a controller including a self-diagnostic function capable of performing safe control and self-diagnosis in parallel, and to provide a self-diagnostic method for the same. SOLUTION: The safety output device includes: an output control part 1 instructing to output normal output data and first self-diagnostic pattern data in synchronization with a control period; a normal output part 2 outputting the normal output data in synchronization with the control period; a test pattern generation part 3 encoding the self-diagnostic pattern data as a pulse train signal having a pulse width not larger than a preset pulse width, and outputting the pulse train signal by a base band transmission system; a composition output part 4 composing and outputting the pulse train signal and a normal output signal; a reconfiguration part 5 decoding an operation end part 13 output signal, and reconfiguring it as second self-diagnostic pattern data; and a comparison part 6 comparing the first self-diagnostic pattern data and the second self-diagnostic pattern data to decide the presence/absence of a difference.

    • 要解决的问题:提供一种用于包括具有能够并行执行安全控制和自我诊断的自我诊断功能的控制器的安全输出装置,并提供用于其的自我诊断方法。

      解决方案:安全输出装置包括:输出控制部分1,其指示与控制周期同步地输出正常输出数据和第一自诊断模式数据; 正常输出部分2,与控制周期同步地输出正常输出数据; 将自诊断图形数据编码为具有不大于预设脉冲宽度的脉冲宽度的脉冲串信号的测试图形生成部3,并且通过基带传输系统输出脉冲串信号; 构成输出脉冲串信号和正常输出信号的合成输出部分4; 重新配置部分5,解码操作结束部分13的输出信号,并将其重新配置为第二自诊断模式数据; 以及比较部6,比较第一自诊断图案数据和第二自诊断图案数据,以确定差异的存在/不存在。 版权所有(C)2011,JPO&INPIT
