セキュリティコードは、データロガーを保護する最も古い方法です。セキュリティコードは、悪意のないいたずら、ハッカー志望者によるデータの整合性に大損害を与える可能性のある行為を阻止することができます。この記事では、さまざまなセキュリティコードと、それらを使用してデータと設定を保護する方法について説明します。
データロガーのセキュリティは最大 3 つのレベルに設定できます。CR1000 より新しいデータロガー (CR6 や CR1000Xe を含む) の場合、有効なセキュリティ コードは 1 ～ 65535 です (0 はセキュリティなし)。3 つのレベルごとに固有のコードを使用することをお勧めします。
銀行に例えると、レベル 3 は銀行の正面玄関です。ロックされている場合、鍵なしでは誰も入れません。レベル 2 は受付エリアで、一部の情報にはアクセスできますが、すべての情報にはアクセスできません。レベル 1 は金庫です。金庫の正しい組み合わせがあれば、すべてにアクセスできます。 レベル 1 (金庫) はレベル 2 (受付エリア) を設定する前に設定する必要があります。また、レベル 2 はレベル 3 (正面玄関) を設定する前に設定する必要があります。レベルが 0 に設定されている場合、それよりも高いレベルもすべて 0 に設定されます。たとえば、レベル 2 が 0 の場合、レベル 3 も...

Why should you use a Constant declaration in your CRBasic program? What is a Constant anyway? In a previous article ("Going Public with Your Variables in CRBasic"), we talked about the Public and Dim variable declarations. Variables are just that—variable; they change. Constants, on the other hand, don’t change;...
