converted array -> msg.payload : undefined ??

[Patrick]

hi.. new here and first steps with node-red.

I had convert a global integer (filled with: 32785) split in a 16Bit-Array.
the array shows as well.

but when I try to compare an object of thay array (p.e. array_status_base2[15]) I receive an msg.payload : undefined

what do I wrong, or where is my fault?

thanks in advance
Patrick


here's my flow:

[{"id":"56f842d.16df13c","type":"debug","z":"d27eace5.68918","name":"","active":true,"console":"false","complete":"false","x":510,"y":60,"wires":[]},{"id":"c4cadc76.48a9a8","type":"function","z":"d27eace5.68918","name":"Test","func":"var status      =   {payload:context.global.wBetriebsStatus_01};\nvar array_status_base2      =   {payload:(context.global.wBetriebsStatus_01.toString(2)).split(\"\")};\nvar heiz  =  {payload:array_status_base2[15]}; \nvar kuehl =  {payload:array_status_base2[14]}; \n\n//    if (array_status_base2[15] === \"1\") var Status_text = \"Heiz-Betrieb\" ;\n//    if (array_status_base2[14] === \"1\") var Status_text = \"Kühl-Betrieb\" ;\n//    if (array_status_base2[13] === \"1\") var Status_text = \"Totzone\" ;\n//    if (array_status_base2[12] === \"1\") var Mode_text = \"Automatik\" ;\n//    if (array_status_base2[11] === \"1\") var Mode_text = \"Handbetrieb\" ;\n    \nreturn [status, array_status_base2,heiz,kuehl];\n","outputs":"4","noerr":0,"x":290,"y":60,"wires":[["56f842d.16df13c"],["56f842d.16df13c"],["56f842d.16df13c"],["56f842d.16df13c"]]},{"id":"b474b5e9.eb98","type":"inject","z":"d27eace5.68918","name":"Test Trigger","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"x":130,"y":60,"wires":[["c4cadc76.48a9a8"]]}]

you have defined 

var array_status_base2      =   {payload:(context.global.wBetriebsStatus_01.toString(2)).split("")};

so array_status_base2 is now an object with a property called payload - which is in turn an array ...

so you would be better off not making that into an object before you do all your comparisons. and then setting that as a pyload just before you send it... eg

var status      =   {payload:context.global.wBetriebsStatus_01};

var array_status_base2      =   context.global.wBetriebsStatus_01.toString(2).split("");

var heiz  =  {payload:array_status_base2[15]}; 

var kuehl =  {payload:array_status_base2[14]}; 

//    if (array_status_base2[15] === "1") var Status_text = "Heiz-Betrieb" ;

//    if (array_status_base2[14] === "1") var Status_text = "Kühl-Betrieb" ;

//    if (array_status_base2[13] === "1") var Status_text = "Totzone" ;

//    if (array_status_base2[12] === "1") var Mode_text = "Automatik" ;

//    if (array_status_base2[11] === "1") var Mode_text = "Handbetrieb" ;

    

return [status, {payload:array_status_base2},heiz,kuehl];

return [status, {payload:array_status_base2},heiz,kuehl];

 
Dave, you made my day!
