2. セットアップとインストール

Proper installation is crucial for the reliable operation of the NI-9203 module. Follow these steps carefully:

1. 電源オフシステム: Ensure the CompactDAQ or CompactRIO chassis is powered off before inserting or removing any modules.
2. モジュール挿入: Align the NI-9203 module with an available slot in the chassis. Gently push the module until it clicks into place.
3. 安全なラッチ: Press the module's latch down to secure it firmly in the chassis.
4. 配線接続: Connect your current input signals to the screw-terminal connector. Refer to the pinout diagram on the module for correct wiring.
   • Connect current sources to AI0 through AI7.
   • Connect the common return path to the COM terminal.
5. システムの電源オン: Once all modules are securely installed and wired, power on the chassis.

3. 操作手順

The NI-9203 module is designed to acquire current signals. Operation typically involves configuring the module through National Instruments software, such as LabVIEW or NI-DAQmx.

3.1.ソフトウェア構成

1. ドライバーのインストール： Ensure NI-DAQmx drivers are installed on your host computer.
2. デバイスの検出: Open NI Measurement & Automation Explorer (MAX) to verify the module is detected and recognized by the system.
3. Create Task: In MAX or your programming environment (e.g., LabVIEW), create a new DAQmx task for analog input.
4. チャネルを構成する: Add the NI-9203's analog input channels (ai0 to ai7) to the task. Specify the measurement type as current and set the input range to ±20 mA.
5. Timing and Triggering: sを構成するampling rate and any necessary triggering parameters for your application.
6. Start Acquisition: Run the DAQmx task to begin acquiring data from the current input module.

3.2.データ取得

The NI-9203 converts analog current signals into digital data. The 16-bit resolution provides precise measurements. Ensure your current sources are within the ±20 mA range to prevent saturation or damage to the module.

4. メンテナンス

The NI-9203 module is designed for robust industrial use and requires minimal maintenance. However, periodic checks can ensure optimal performance and longevity.

• クリーニング： モジュールは清潔に保ち、ほこりやゴミが付かないようにしてください。清掃には柔らかく乾いた布を使用してください。研磨剤入りの洗剤や溶剤は使用しないでください。
• 接続の整合性: Periodically inspect the screw-terminal connections for tightness and ensure no wires are loose or frayed. Loose connections can lead to intermittent readings or signal loss.
• 環境条件: Ensure the module operates within its specified temperature and humidity ranges to prevent damage.
• ファームウェアの更新： Check the National Instruments website periodically for any available firmware updates for the NI-9203 module. Follow the provided instructions for any updates.
