Http request payload

General
1

Hello
Somehow I can't get to the solution.
Is intended for an IO-Link Device with two analog out.
I have two sliders for entering the target output value, adding folders to 16bit Value Topic, merging them into one number, and now I want to transfer this to the master with an http request, but how do I pass the new value to the sliders?
I'm grateful for any help.
Philipp

You should have value not "value" in function node 7.

var value = msg.payload.pdOut
msg.payload = { 
    code: "request", 
    cid: "4", 
    adr: "/iolinkmaster/port[1]/iolinkdevice/pdout/setdata",
    data: value   // <<<<<<<<<<< here
};

return msg;
3

Thanks Dave,
it was my fault, but the return value have to be inside some quotation marks like this "value".

4

Do you mean that msg.payload.data has to be a string not a number, for example "42" ?
If so try const value = msg.payload.pdOut.toString()

Hi and welcome to the forum.

I hope @dynamicdave reply helped you.

I just want to add you are using far to many function nodes, which have overheads. here is an example of your flow minimised.
