多個串行端口上的腳本Zaber設備

Question

是否可以將Zaber設備連接到多個串行端口並通過單個腳本控制它們？該腳本正在運行Zaber Console，並且應該能夠協調任一端口上的設備之間的運動。

Answer 1

是的，您可以在腳本中打開更多串行端口。您只需複製我們的Zaber控制檯程序通常爲您所做的所有配置。串行端口打開後，您可以正常使用會話對象。爲了協調兩個設備之間的移動，您使用對話主題對象來等待響應。有關更多詳細信息，請閱讀Zaber庫幫助文件。你可以在腳本編輯器的幫助菜單中找到它。

// Example C# script showing how to open a second serial port and coordinate 
// moves between the two. 
#template(methods) 

public override void Run() 
{ 
    // First port is the one that Zaber Console has already opened. 
    var portFacade1 = PortFacade; 
    // Now, we're going to open COM2 in the script. 
    // The using block makes sure we don't leave it open. 
    using (var portFacade2 = CreatePortFacade()) 
    { 
     portFacade2.Open("COM2"); 

     // Start a conversation with a device on each port. 
     // Note that the device numbers can be the same because they're on 
     // separate ports. 
     var conversation1 = portFacade1.GetConversation(1); 
     var conversation2 = portFacade2.GetConversation(1); 

     while (! IsCanceled) 
     { 
      MoveBoth(conversation1, conversation2, 0); 
      MoveBoth(conversation1, conversation2, 10000); 
     } 
    } 
} 

private void MoveBoth(
    Conversation conversation1, 
    Conversation conversation2, 
    int position) 
{ 
    // Start a topic to wait for the response 
    var topic = conversation1.StartTopic(); 
    // Send the command using Device.Send() instead of Request() 
    // Note the topic.MessageId parameter to coordinate request and response 
    conversation1.Device.Send(
      Command.MoveAbsolute, 
      position, 
      topic.MessageId); 

    // While c1 is moving, also request c2 to move. This one just uses 
    // Request() because we want to wait until it finishes. 
    conversation2.Request(Command.MoveAbsolute, position); 

    // We know c2 has finished moving, so now wait until c1 finishes. 
    topic.Wait(); 
    topic.Validate(); 
}
