Software Signal Pulse#

Software Signal Pulseカメラ機能を使用すると、複数の目的に使用できるソフトウェアコマンドを実行できます。

The feature serves as an alternative to software commands that are limited to a specific purpose, e.g., the TriggerSoftware command.

Why Use Software Signal Pulse Commands#

Standard software commands can only be used for a single purpose. For example, you can use the TriggerSoftware command only to trigger the camera and the UserSetLoad command only to load a user set.

イメージ SoftwareSignalPulse command, however, can be used for multiple purposes. You can also use the command to control multiple camera features in a single operation.

仕組み#

Supported Camera Features#

カメラのモデルによっては、Software Signal Pulse機能を使用して次のカメラ機能を制御できます。

• Triggered Image Acquisition
  必要に応じてカメラをトリガーできます。
• Sequencer (ace Classic/U/L USB)
  You can advance the sequencer, reset the sequencer, or both.
• Counter
  特定のカメライベントをカウントできます。
• Timer
  タイマー出力信号を設定できます。

Signal Channels#

Depending on your camera model, up to three signal channels are available, e.g., SoftwareSignal1 and SoftwareSignal2.

別々の信号チャンネルを使用すると、制御するカメラ機能を分離したままにしておく場合に便利です。例えば、信号チャネル1を介してカメラをトリガーし、信号チャネル2を介してシーケンサーを進めることができます。

Using Software Signal Pulse Commands#

To configure the SoftwareSignalPulse command:

1. Set the source of the desired camera feature to one of the available signal channels. For example, set the TriggerSource parameter to SoftwareSignal1.
2. Software Signal Pulse機能で制御するすべてのカメラ機能について、上記の手順を繰り返します。複数の機能を同時に制御する場合は、それぞれに同じ信号チャンネルを割り当てます。制御された機能を分離しておく場合は、それぞれに異なる信号チャンネルを割り当てます。

To execute a SoftwareSignalPulse command:

1. パラメーターを SoftwareSignalSelector parameter to one of the available signal channels, e.g., SoftwareSignal1.
2. Execute the SoftwareSignalPulse command.
   A software signal is sent. The signal uses the selected signal channel and executes the assigned action(s), e.g., advances the sequencer.

サンプルコード#

// Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.SequencerTriggerSource.SetValue(SequencerTriggerSource_SoftwareSignal1);
// Select software signal channel 1
camera.SoftwareSignalSelector.SetValue(SoftwareSignalSelector_SoftwareSignal1);
// Execute the command
camera.SoftwareSignalPulse.Execute();

INodeMap& nodemap = camera.GetNodeMap();
// Set software signal 1 as "path 0" trigger signal (sequencer reset)
CEnumParameter(nodemap, "SequencerTriggerSource").SetValue("SoftwareSignal1");
// Select software signal channel 1
CEnumParameter(nodemap, "SoftwareSignalSelector").SetValue("SoftwareSignal1");
// Execute the command
CCommandParameter(nodemap, "SoftwareSignalPulse").Execute();

// Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.Parameters[PLCamera.SequencerTriggerSource].SetValue(PLCamera.SequencerTriggerSource.SoftwareSignal1);
// Select software signal channel 1
camera.Parameters[PLCamera.SoftwareSignalSelector].SetValue(PLCamera.SoftwareSignalSelector.SoftwareSignal1);
// Execute the command
camera.Parameters[PLCamera.SoftwareSignalPulse].Execute();

CHECK(errRes);
/* Execute the command */

# Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.SequencerTriggerSource.Value = "SoftwareSignal1"
# Select software signal channel 1
camera.SoftwareSignalSelector.Value = "SoftwareSignal1"
# Execute the command
camera.SoftwareSignalPulse.Execute()
