What happens is that by wanting to read the IR tags (30000) could only get the variables of integer type, but to pass it to floating from the label of data type This gives me a very high value, I am new to the subject and I would appreciate if anyone can support me in this.

I’m not sure I understand your questions. Can you show the Modbus value you’re trying to read, and the configuration of the tag that’s not giving the unexpected value?

Hello witman, look on the Ignition side I entered this address:

 ![ignition](https://us1.discourse-cdn.com/inductiveautomation/original/2X/e/e2ae9493fbe0896ca6793be7c25669aa9bd1eab0.png)

But I do not get the correct data, what brings me is the following:

If I put (holding Register (Float) also gives very high data, thanks for helping.

Maybe you need to use the Reverse Word Order setting?
