(tagName 1, value 1, timestamp 1, value 3)

can you help me.

msg.payload : Object
object
deviceName: "cell_3"
**tagName: "HMI_H1_Temperature"**
deviceID: "49D9941E-8915-44E2-BCC9-0A0D0652389F"
success: true
datatype: "real"
timestamp: 1654751958598

metadata: object
registerId: "E87D5CED-0734-4947-8963-0F111A6BCF1E"
description: "Temperatura H1 cela 3"

msg.payload : Object
object
deviceName: "cell_3"
tagName: "C31_Tracking_Data"
deviceID: "49D9941E-8915-44E2-BCC9-0A0D0652389F"
success: true
datatype: "word"
**timestamp: 1654752905277**

const a = new Date();
const top = msg.topic;
const pay = msg.payload;
const temp = msg.payload.success;
const temp1 = msg.payload.tagName;




if(temp  && temp1)
{
 if(temp  && temp1 === "C31_Tracking_Data")
    {
         let datafilter1 = msg.payload;
         let current1 = datafilter1.value;
         let obj1 = datafilter1.tagName;
         let previous1 = context.get(obj1);
        context.set(obj1,current1);  
     }

 if(temp  && temp1 !== "C31_Tracking_Data") // Checks if the message succeeded and if the tag name exists before continuing.
    {
           let datafilter = msg.payload;
           let current = datafilter.value;
            let obj = datafilter.tagName;
            let previous = context.get(obj);
             context.set(obj,current);
    }  
          
            msg.topic = "Dom/SC3";
          msg.payload = {"location": obj, "utctimestamp_ms": a.getTime(), "code": current, "taskID": current1 };
   node.status({fill:"blue",shape:"dot",text: (obj, current)});
  return msg;
}

What do you expect the output to be from these 2 objects? Do you want all values avaiable in 1 message OR do you really want values of 2 objects merged into 1 object & if so, then what happens when there are 2 properties with the same name but different values?

Yes, but you will need to correctly export the data - use the "copy value" button that appears under your mouse when you hover over the debug message properties.

I have connect to PLC, , when parts stop on station I would like add to IDparts to fiew parametes.

(tagName.paylad 2, value.paylad 2, timestamp.paylad 2, value.paylad 1)
(tagName.paylad 3, value.paylad 3, timestamp.paylad 3, value.paylad 1)
(tagName.paylad 4, value.paylad 4, timestamp.paylad 4, value.paylad 1)
(tagName.paylad 5, value.paylad 5, timestamp.paylad 5, value.paylad 1)
end next
part go on next station,

IDparts = payload 1 -> C31_Tracking_Data
value: 10
data = payload 1,2,3,4.. -> HMI_H1_Temperature
tagName: "HMI_H1_Temperature"
timestamp: 1654751958598
value: 37.457176208496094

I can't download the data and add it.
msg.payload = {"location": tagName, "utctimestamp_ms": a.getTime() ,"code": payload2.value restCode, "taskID": " payload1. value "};
