Abstract

ＥＣＣメモリの永久故障の存在を知ることができ、永久故障が累積して予兆ないまま修正不可能となることを避けることができる制御装置を提供する。メモリ診断手段(１１)は、電源投入のときに電源投入ステータスをセットしてＥＣＣメモリ(１２)を診断し、再起動手段(１３)は、メモリ診断手段(１１)が電源投入ステータス中にＥＣＣメモリ(１２)の修正可能エラーを検出したときは再起動を掛ける。動作処理手段(１４)は、メモリ診断手段１１がＥＣＣメモリ(１２)の修正可能エラーを検出しないときは電源投入ステータスをリセットして通常動作を行うとともに、ＥＣＣメモリ(１２)の修正可能エラーを検出したが電源投入ステータス中でないときは通常動作を行う。
