You also might have a look at the VPN MTU settings, as your problems seems related to that.

i do see now, i got some Years in there that are far from now, gehehe . thats why it didnt had effect probably..

thnx for the pointers.

i was refering to this :

Thanks Phil(lips) , i am going to play with it , little stupid off topic question :

"How to purge all Information on "Urgent events" or "information " . seems there is no option/knob when viewing the list. ( clear dates , seem to do nothing when selected periode )

Did made some progress, via an other approach ;

Created : tcp/ip source ( 2 sec update period )
Created : Data Point to that :

     "loggingType":"NONE",
     "dataType":"ALPHANUMERIC",
     "queryable":true,
      "readCommand":"<your_hex_request_for_your_device>",
      "settable":false,
      "valueIndex":0,
      "valueRegex":".*",

Created META-source
Created : Data Point to that :

     "name":"DoorAlarm",
     "enabled":true,
     "dataType":"ALPHANUMERIC",
     "updateContext":true,
     "varName":"p110"

added in script field :

// get Hex from source

// Alarm relays Bit ( 1 is Alarm )
var DoorAlarm = /[0-9A-Fa-f]{185}([0-9A-Fa-f]{1}).*/.exec(p110.value); 
var extractedValue = DoorAlarm[1];

// payload
return "DoorAlarm- " + DoorAlarm[1];

...

So i added some other "Meta-data points" for other values.
This works ok, and i can understand how it works.

Now the first approach has probably benefits in setting up many same kind devices/values i guess , so i am focusing on that as well , as i would like to understand how that should work.

Alright. made some changes as, reading where not what the should be. now i get the right results from reading the Hex.

Script "message Queue"

// get Hex from source

var busVoltage = /[0-9A-Fa-f]{30}([0-9A-Fa-f]{16}).*/.exec(source.value); 
var extractedValue = busVoltage[1];

var PsuLoad = /[0-9A-Fa-f]{78}([0-9A-Fa-f]{16}).*/.exec(source.value); 
var extractedValue = PsuLoad[1];

// Alarm relays Bit ( 1 is Alarm )
var Alarm = /[0-9A-Fa-f]{185}([0-9A-Fa-f]{1}).*/.exec(source.value); 
var extractedValue = Alarm[1];

// door alarm Bit (1 is Door open )
var DoorAlarm = /[0-9A-Fa-f]{185}([0-9A-Fa-f]{1}).*/.exec(source.value); 
var extractedValue = DoorAlarm[1];


var message = busVoltage[1];

function toASCII(message) {
  var result = "";
  while(message.length > 1) { //parse two characters at a time
     var charCode = message.substr(0, 2);
     result += String.fromCharCode( "0x" + charCode );
     message = message.substr(2); 
  }
  return result;
}

// swap bytes /hex

function swap32(val) {
return ((val & 0xFF) << 24)
       | ((val & 0xFF00) << 8)
       | ((val >> 8) & 0xFF00)
       | ((val >> 24) & 0xFF);
}

//print (message);


function hex2float(num) {
    var sign = (num & 0x80000000) ? -1 : 1;
    var exponent = ((num >> 23) & 0xff) - 127;
    var mantissa = 1 + ((num & 0x7fffff) / 0x7fffff);
    return sign * mantissa * Math.pow(2, exponent);
}


function roundToTwo(num) {    
    return +(Math.round(num + "e+2")  + "e-2");
}


// covert Hex to String
var subresult = (toASCII(message));
// create human readabe number
var result = (roundToTwo(hex2float("0x" +subresult)));

// send payload
return target.value + "MainAlarm-" + Alarm[1] + ";" + "Door-" + DoorAlarm[1] + ";" + "busvolt-" + result + ";" ;

at this point i get as result : MainAlarm-0;Door-0;busvolt-53.68;

thats correct.

so i have right input , further i am still completely lost in how i should proceed.

i added my other (modbus) device and thats straight forward , enter the source and add data points to it. thats easy.
now why cant i see the logic for the other source..

Well, looks something is working :

i ques this is normal ?

this is what i got,

and point link details :

"messageIdentiefier" is the variable/object coming from point link script right ?

ok learned "Object"

Can someone point me some explanation links about :

var identifierMap = { "messageIdentifier" : contextPoint1 ....  } 

cant find much on " indentifierMap " on internet somehow.

identifiers, object etc, is probably JavaScript terms....hmm and i was thinking it was almost done, gehehe.
i need a neighbor with programming skills ( the neighbors house is for sale btw )
so back to learning books ..

i got this in " point links as script " , is this ok ?

and what to put in :

the script - source script. ?

i tried 1000 different combinations. and reading the wiki / manuals. but sorry, i don't
get it...

can you simply , ping the server ?

now put all this in Mango needs again some pointers i think..

Perfectum Resultativum ;

little update ,

i found that i need to convert in javascript the with sort of

function hex2float(num) {
var sign = (num & 0x80000000) ? -1 : 1;
var exponent = ((num >> 23) & 0xff) - 127;
var mantissa = 1 + ((num & 0x7fffff) / 0x7fffff);
return sign * mantissa * Math.pow(2, exponent);
}



window.alert (hex2float("0xA4703942"));
//flipped does the trick
window.alert (hex2float("0x423970A4"));
// outcome 46,36..... ( not rounded )

``

so little progress here.

Alright i got it. thnx.

i had little play with :

var busVoltage = /[0-9A-Fa-f]{46}([0-9A-Fa-f]{8}).*/.exec(source.value);
var extractedValue = busVoltage[1];

print (busVoltage[1]);

Script result:
42453939

so that works, i found code for converting the hex to float, but no knowledge of writing (java) coding structure is a show stopper at the moment. but i do have fun learning , gehehe

That fixed it indeed.

i noticed i can check scripting code by clicking on the "little green Script dot".

Its still not clear to me.

• Data source collects makes connection to device. ( interval for set here )
  that is the easy part,

• tcp/ip Data point asks for data ( command data point )

• tcp/ip Data point response listen for data

• tcp/ip Data point "link" this to Scripting data point, "message queue" datapoint.

• in the "link" script screen i put in ?? which pieces of code ?

• in the Script Data source i also put in which pieces ?

i tried a lot of combinations, but i don t see it.

i removed everything and restarted Mango.

The "value index: set to 1 was indeed the bottleneck. ( i checked to see what difference 0 or 1 made.

so i have data again,

The errors
"

in terminal are still there do.

i don t care at the moment, as getting things running is more important to me at the moment.

now i start building COMMAND and RESPONSE from the beginning of the forum..

Nope, reboot did not help, rebooting device and connections did not help.
