HMI Modbus TCP/IP Device Communication

Hello,

I have Delta DOP110 IS hmi and i have a modbus tcp device.

I want to communicate hmi and device with modbus tcp/ip but i didn't understand device's register address. I have never seen like this type addressing.

For example, output bytes 2,3 fault code, What is the register address?

Modbus is 16 bit what you have there is 32 bit, you have to combine 2 ond 3 in the plc to read it, I think that is your problem
 
I think the source of the confusions is because you are looking at documentation for the wrong protocol.

The image you show seems to be from the product's PROFIBUS documentation:

Try the Modbus documentation here:

Maybe you are right. In Lamtec website this document is modbus tcp document. I cant attech the document because of its size
