  Are you trying to dertmine if a port has been defined for a particular TP or what port on a TP may have triggered the current event?
  
  In either case you would need to use the embedded object.
  
  If you're trying to determine if a port has been defined then you would need to use a DATA_EVENT handler since if a port is defined it will generate an online event during start up so you could use that event to set a flag in an array like this:

  DATA_EVENT[dvTPDevicePort]//IP or SERIAL COMMS 
       
       {
       ONLINE:
  	  {
  	  nTP_PortsUsedArry[data.device.port] = 1 ;
  	  //other stuff ;
  	  }
       }
  

  
  I don't now what you would do with this but I suppose it might have its uses.
  
  To determine what port initiated an event you could something like this:

  BUTTON_EVENT[dvTPDevicePort,nBtnArry] 
       
       {
       PUSH:
  	  {
  	  nCurrentTP_EventPort = button.input.device.port ;
  	  //stuff
  	  }
       }
  
  

  
  For level events use "level.input.device.port" & channels events use "channel.device.port".
  
  What are you trying to do?

  is there a way to track which port on a touch panel is being used? Say if port 4 on a touch panel is being used? ex: 10001:4:0

  You can look at the online tree in Netlinx Studio and each port in use will show up under the device.
