RapidData "hidden GeneralException" on FP SDK 5.14

Developer Tools
1

Hi,
I have found a “hidden ABB.Robotics.GeneralException” by console connection to controller when I try to get a RapidData that is not present in a specific system module. I need to know if this RapidData is present to do some things or if not present to do other…

If RapidData is present there aren’t “hidden exception” and “[Fp]: …” message from console.

now a piece of my code:

…
Task tasks = controller.Rapid.GetTasks();
try
{
Trace.WriteLine(string.Format(“DataController() → getting RapidData _EFdo”));

RapidData _EFdo = tasks[0].GetRapidData(“SM_CONF”, “EFDoButtons”);
//“SM_CONF” is my system module and always is present, “EFDoButtons” if present is a CONS string

if(_EFdo != null)
{
// do some things…
}
else
{
// do other things…
}
}
catch(ArgumentNullException ex) //as wrote on FP SDK about working with RapidData in “Using the FlexPendant SDK - Using the Controller API - Rapid domain”
{
Trace.Fail(string.Format("DataController() Error: → RapidData EFDoButtons is not present in SM_CONF " + ex.Message));
}

I tryed also with “ABB.Robotics.GeneralException” instead of “ArgumentNullException” in catch statement but on HyperTeminal always I can read this message from FP:

[fpsdk]: DataController() → getting RapidData _EFdo

  • Is normal this message also if my get statement is in try/catch block?? where is wrong?
  • This hidden exception ban create some problems for the proper execution of the application? (yes, I’m always verify if my variabile if “null” before using it).

Sorry that I don’t have the time to make a proper test+answer. So I can’t answer why you get the error you do.

Now as a workaround you can check if the data is there using SearchRapidSymbol before using it. Since you know where its location, name and type it shouldn’t even be a drain on any resources.

But why do you use the tasks instead of direct access? Is it a multimove system?

For the lurkers; direct access is like this:
RapidData rd = aController.Rapid.GetRapidData(“T_ROB1”, “USER”, “reg1”);

Hi John,
tank you for you answer and suggestion. Don’t worry if you haven’t time to try it, mee too and with too many things to do.. :stuck_out_tongue_winking_eye:
About your questions:
The system is not a multi move, I probably made ?_ misuse of “tasks[..].GetRapidData(..)” method.
So I’ll try to use first “SearchRapidSymbol” and after “…Rapid.GetRapidData(..)” to see the other any “new” messange by console connection with controller, and I’ll get to you a right feedback about it.

Tank you very much
regards Emanuele

Hello,
I have tried with direct access “acontroller.Rapid.GetRapidData(“T_ROB1”, “MyModule”, “MyVar”);” but the problem it’s same..
