Abstract

PURPOSE:To increase the safety of a process, by commonly using a display element for a display of a process relating data, storing the career even for a temporary failure and leaving the result as far as the operator erases the result with an operation key. CONSTITUTION:Through a display mode switching key, a display element DPE is commonly used and the information of result of diagnosis and control operation is displayed selectively on a set dispaly SDP. The contents of failures are stored as heavy failures and light failures, and if a heavy failure takes place, a display mode is selected to the RUN mode for automatically immediate display and the renewal of the control operation output is stopped. On the other hand, in case of a light failure, display is made when the RUN mode is selected with a display mode switching key, and when the display mode is switched into the FUNC mode from the RUN mode through the operation of this key, the storage of the contents of failure is erased and an element DPE is commonly used and the failure of automatic recovery can be confirmed.
