Read Instructions Modbus Node


I’m new here on the platform and beginner in programming. I have a question about when to use it and what are the differences between the types of Node reading instructions.

More precisely in types ( input-register, holding-register, discrete-input, coil or read-device-identification).

I didn’t find information in the node docs.
Could someone help me understand better?

Hi @ROMULO_ACERBI_MARIN, and welcome to the Losant Forums!

This is more of a Modbus question than a Losant question; there are several articles that explain the difference between the different register types. I find this one especially helpful:

I would also consult the operating manual of the hardware you are trying to integrate with for the different register types, addresses, and lengths you are trying to read.

Let us know if you have any other questions!
