Issue a simple message

Messages can be triggered in 2 ways: simple and complex.

This Sample shows how a simple message is triggered in the PLC. The Code used for a simple message is shorter than for a complex message, but you will have less configuration possibilities.
 

1. Create a new PLC-Project.
• Choose PC (i386) as Target System
• 
• Keep the standard task-settings.
• Create a new ST-program.
• 
• Open the menu Window -> Library Manager and add TcSystem.lib to the project.
  Now you have access to the ADSLOGEVENT function block.
2. Use the TcEventConfigurator to create a quit-requiring message with the SourceID 17001 and EventID 1
3. Add following code to the project:
4. (*Variable-declaration*)
   VAR
       event    : FB_SimpleAdsLogEvent;
       bEvent   : BOOL;
       bQuitEvt : BOOL;
   END_VAR
    
5.  
6. (*PLC Code*)
   Event( SourceID  := 17001,
          EventID   := 1,
          bSetEvent := bEvent,
          bQuit     := bQuitEvt);
4. Start the PLC Program.
5. Start the TcEventbar ('TwinCAT/Eventlogger' directory).
6. By toggling bSetEvent1 the message will be triggered. Rising edge starts the message, otherwise it will be reset.
7. Toggling bSetEvent won't reset the message cause it is a quit-requiring message. It must be deleted before bSetEvent can be reset and bQuitEvent must be set.
