What am I doing wrong here? You can see the values have the ascii data in the top message but after my function I get no values? Im trying to just take the ascii values in the buffer or array out of the modbus read and put them into a string so I can pass it to a web service. [image]

Try to use the array spread operator (...) in the function msg.value = String.fromCharCode(...msg.payload.data) return msg;

I was probably not using it right. Ok, i deleted the unused parts of the msg and got it the same as the pic 2 above but still no go quite yet. See how i dont get that soap envelope back like in pic 2? [image]

Rather than a screenshot of the function paste it here using the </> button at the top of the forum text entry field when pasting it in.

Yea the modbus breaks and the soap so i figured it wasn't very useful to post the code but here it is so far. [{"id":"e6693df7.a3cfa","type":"tab","label":"Flow 4","disabled":false,"info":""},{"id":"eb571ded.e53f3","type":"modbus-read","z":"e6693df7.a3cfa","name":"","topic":"","showStatusActivities"…

Edit you post and paste again using [image]

Also what is the global context variable SN showing in the context side bar?

Also you need to post the flow correctly so we can import it, as described by @UnborN and myself.

I had to change from complete msg to normal debug and than you see the envelope data. All good. Deleted the pics and posts so people dont get confused.

All you needed to do to see the contents of the payload object was to click on it in the debug. So is everything working now?

This worked and than I had to change the debug output

Unless you tell us which function is the "soap function", what the input to the function is and what output you are expecting then we don't know where to look.
