Description
電源スイッチ22がオフされると、監視装置3のリレー駆動部14がこの電源スイッチ信号SWのオフ信号を入力するが、電源スイッチ信号SWは波形整形部13を通じて演算装置2の実制御部7にも入力される。演算装置2の実制御部7は、この電源スイッチ信号SWのオフ信号を受け付けると、シャットダウン処理、所謂停止処理を行う。
仮に、カウント禁止フラグを設けるなどの処理を行っていないと、電源スイッチ22がオンからオフ、再度オンされたときに、リセット回数を所定回以上カウントしてしまうことになりフェールセーフ処理に移行してしまう虞がある。
本実施形態の特徴を概念的にまとめる。
演算装置2が異常を生じたときに監視装置3はリセット信号RST2のアクティブレベルをリセット信号線24を通じて演算装置2に出力する。機能監視部19は、リセット信号線24に発行されるリセット信号RST2のアクティブレベルが演算装置2の本来の異常時に生じる監視対象リセット信号となるか又は演算装置2の本来の異常時以外に生じる監視対象外リセット信号となるかを判別する。このため、リセット信号RST2のアクティブレベルがリセット信号線24に発行されたとしても、このリセット信号RST2のアクティブレベルが演算装置2の本来の異常時に生じたものであるか、本来の異常時以外で生じたものであるかを判別できる。このとき、本来の異常時以外で生じたものであるときには、フェールセーフ処理に移行することなく通常制御を継続できる。
本発明は、前述した実施形態に限定されるものではなく、種々変形して実施することができ、その要旨を逸脱しない範囲で種々の実施形態に適用可能である。例えば以下に示す変形又は拡張が可能である。
特許請求の範囲に記載した括弧内の符号は、本発明の一つの態様として前述する実施形態に記載の具体的手段との対応関係を示すものであって、本発明の技術的範囲を限定するものではない。前述実施形態の一部を、課題を解決できる限りにおいて省略した態様も実施形態と見做すことが可能である。また、特許請求の範囲に記載した文言によって特定される発明の本質を逸脱しない限度において、考え得るあらゆる態様も実施形態と見做すことが可能である。
