So I`ve been reading data through the serial modbus node. I then connected it directly to a write text file node hoping that I could use the data later. Only issue is - the data comes through as a raw format like this ----
apologies as I know nothing about modbus - but that looks more like serial data received at the wrong speed / baud rate - does modbus have a fixed baud rate ?
In addition (or alternatively) is not modbus data binary rather than human readable?
I would start by feeding the output of the modbus into a debug node and make sure you get sensible data.
The modbus response reads it as a buffer but I dont know what the initial decoder is doing , ie what the serial modbus node reads it as before its changed into something else
