  • Control device
    Patent number: 9952579
    Abstract: A control system CPU card includes a control CPU chip having a first core and a second core, and a main memory for storing information. A standby system CPU card includes a standby CPU chip having a first core and a second core, and a main memory for storing information. An I/F performs communication to allow the CPU cards to share the information. In the control system CPU card, when the first core is normal, the first core performs control calculation and outputs a calculation result. When the first core is abnormal, the second core is switched to a control core, to perform control calculation and continue output of a calculation result. When the cores are both abnormal, system switching is performed from the control system CPU card to the standby system CPU card.
