Modbus RTU - NeuronL503 - Mervis
I'm used to working with Codesys and I can't find my way fully around Mervis yet :)
So I am trying to read out some PPM CO2 readings from a Modbus RTU transmitter
I'm trying to read out the CO2 fast parameter: Address: 29 + 30
It seems I can read out some values, but I have to combine them into a REAL, in Codesys I use UNION to combine both words (and swap them) into a REAL.
What is the easiest way to achieve this within Mervis?

Hi @OlivierP ,
you can change the byte order via MultiByte Order:
