PURPOSE:To prevent that the unnecessary signal is outputted from the process output card and to avoid the occurrence of the accident by resetting the output memory of the process output card at the time of return after the abnormality occurs at the part except a CPU. CONSTITUTION:When an electric power source device comes to abnormal, an output 11a of an AND circuit 11 is turned off by the signal from the output normality detecting circuit and the trouble of the system is informed through an output circuit 13 to the external part. A CPU continues the normal action, the CPU 1 receives an interface signal 14 and resets the output memory of a memory part 3-1 of a process output card 13. |
