Device Port Tracking

ondrovic

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

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?

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