I want to split the data stream I receive into different variables. The values are separated by a comma. Enclosed a copy of the data stream 50,57,51,54,0,1,2,2013,2024,32,40561,0,587,0,0,61536,4000,8675,0,1392,45600,3485,52935 Enclosed the node with which I want to read a PV memory via Modbus TCP …

Please see this post for how to format a flow so that it can be imported. How to share code or flow json Please post a screenshot of the output from the modbus node in a debug node so we can see exactly what we are dealing with.

Look at the buffer-parser node. It is ideal for taking a buffer and turning it into a nice key/value object.

or if it is really just a string then maybe the CSV node

I suspect as the OP mentions Modbus TCP and "values are separated by a comma" is more so an array data items that need coercing into nice values. I could be wrong - it happens :smiley:

Indeed - but when they include more than just bytes it looks less like a buffer. so ... who knows... (well hopefully OP :wink:

I am now getting values. How can i convert the value to sint16 now?
