Send multiple data in a single message

Hi everyone!!

I hope you are very well!

I have the following problem, I am receiving data via modbus in array, but I need the transformed value.

The problem is that I am dividing the message into parts to be able to convert it into float(le), the issue is that now 3 final messages are being sent instead of just 1.

I need these 3 messages:

It is sent in 1 single message that contains the 3 previous ones

You need to look at the join node.

Why are you dividing up the data in an array?

Do you have a specification? Without info of what the values should be I can only guess the LE/BE/Swap and byte offsets.

e.g. what are you expecting from the demo data in your testArray of [66,80,148,245,66,80,148,245,66,80,148,245,66,80,148,245,148,245] ?

Given this data ↑ what would you expect to see in CT1. CT2 and CT3?

As far as I can see you can simply add all of the parts to 1 buffer parser...
