Line Overload Status#

Line Overload Statusカメラ機能を使用すると、GPIOラインが過負荷（つまり、電力供給が不適切）になっているかどうかを判断できます。

機能を使用する#

Line Overloadの原因#

GPIOラインが出力ラインとして設定されている場合は、カメラのトピックで指定されている適切な出力信号電圧を適用する必要があります。カメラのトピックは、「モデル」セクションにあります。

If you don't apply the appropriate voltages, a line overload may occur. As long as the absolute maximum voltage of the camera is not exceeded, the camera can detect the overload and report it via the BslLineOverloadStatus parameter.

I/Oラインの過負荷ステータスの判別#

GPIOラインが過負荷になっているかどうかを確認するには、次の手順に従います。

  1. Set the LineSelector parameter to the desired I/O line, e.g., Line1.
  2. Get the value of the BslLineOverloadStatus parameter. The parameter is read-only.

A value of false (0) means that the GPIO line is not overloaded.

A value of true (1) means that the GPIO line is overloaded. Check the configuration of your I/O lines.

全I/Oラインの過負荷ステータスの判別#

To determine the overload status of all I/O lines in a single operation, read the BslLineOverloadStatusAll parameter. The parameter is reported as a 64-bit value.

情報

The BslLineOverloadStatusAll parameter is only available via the pylon API, not via the pylon Viewer feature tree.

値内の特定のビットは、I/Oラインに関連付けられています。各ビットは、関連するラインのステータスを示します。

  • ビットが0の場合、関連付けられたラインは過負荷になりません。
  • ビットが1の場合、関連付けられたラインは過負荷になります。I/Oラインの設定を確認してください。

ビットとラインの関連付けは次のとおりです。

  • ビット0はLine1のステータスを示します。
  • ビット1はLine2のステータスを示します。
  • ビット2はLine3のステータスを示します。

Example：すべてのラインが高 = 0b111

情報

If the Line Inverter feature is enabled, the camera inverts the BslLineOverloadStatusAll parameter value. All 0 bits change to 1, and vice versa.
