FAULT DECIDING METHOD FOR CONTROLLER

摘要

PURPOSE:To decide the fault of a certain controller through another controller. CONSTITUTION:The faults are decided between the controllers 4 and 7 provided with the computers 11 to program-control each controlling/ object system. Each of both controllers 4 and 7 produces the fault diagnostic signals in each fixed cycle by a program. The fault diagnostic signal of one of both controllers is received by another controller. The controller that received the fault diagnostic signal decides whether this signal is normal or not to decide the fault of another controller.
