Converting a Data Event Variable to a Level

Have you tried SEND_LEVEL? Sounds like the right thing to do in your application.

this is too funny, a month or so ago I had reason to look at a very similar question. Here's what I did (it works):

		if(find_string(data.text,'DL,[',1))
		{
			remove_string(sTextBuffer,':',1)
			nzone = atoi(sTextBuffer)
			remove_string(sTextBuffer,',',1)
			nlightLevel[nZone] = type_cast(type_cast(atoi(sTextBuffer)) * 2.55)
			send_level dvTPLights, nLightLevelNbr[nZone], nLightLevel[nZone]
		}

Should we have a separate thread combining all these type of questions? Time's wasting.

What does the TYPE_CAST do?

Allows you to put a float or double into an integer w/o producing a compiler warning. The result of n x 2.55 would require a var delcared as a float or double to contain it. Type Cast allows you to scrap the decimal portion of the result w/o the warning.

If the lights are 0-100 based I would forgo the multiplication and just make the bargragh 0-100 too and then send straight level values w/o conversion.

//Request the current intensity of processor 1, link 1, MI address 0, RPM module 2, zone 4
//                                    //DL, [01:01:00:02:04], 50  //RPM dimmer
if(find_string(DATA.TEXT,'DL,[',1))   //DL, [01:04:03:05:07], 50  //H48 dimmer
     {
     STACK_VAR INTEGER nProcessor ;
     STACK_VAR INTEGER nLink ;
     STACK_VAR INTEGER nRouter ;
     STACK_VAR INTEGER nBus ;
     STACK_VAR INTEGER nDimmer ;
     STACK_VAR INTEGER nLevel ;
     
     nProcessor	= atoi(remove_string(DATA.TEXT,':',1)) ;
     nLink	= atoi(remove_string(DATA.TEXT,':',1)) ;
     if(nLink < 8)
	  {
	  nRouter = atoi(remove_string(DATA.TEXT,':',1)+1) ;//add 1 so it's not zero base
	  nBus	  = atoi(remove_string(DATA.TEXT,':',1)) ;
	  nDimmer = atoi(remove_string(DATA.TEXT,',',1)) ;
	  }
     else //RF Dimmer
	  {
	  nRouter = 0 ; //no router for RF dimmers
	  nBus	  = atoi(remove_string(DATA.TEXT,':',1)) ;
	  nDimmer = atoi(remove_string(DATA.TEXT,',',1)) ;
	  }
     nLevel = atoi(DATA.TEXT) ;
     
     //create a structure or array to hold values globally 
     nDimZone[(*do math on above vars based on your system configuration*)] = nLevel ;
     
     SEND_LEVEL dvTPLights,1 (*level channel*), nLevel ;
     }

Now depending on the value received you may stil need to convert from ascii to integer like above.
