HC900 Modbus TCP

[_V_]

Hey everyone, Im kinda of stuck in a situation and Im asking everyone support on this please, I truly need everyone help.

Here is the situation, I am doing a project and I need to communicate between HC900 (using the software designer software) and ABB variator ACS880, and I want to read values from the variator to the PLC and write values from the PLC to the variator.

I am reading manuals and manuals and I can't get nothing, by the way I am using fena-21 on the variator for the ehternet modbus communication.

So guys how do I read and write ? I know I have to use function block modbus tcp, put the IP of the slave (variator) and but big endian, then I use register on the read tab and what now ? what is adress(hex) ?

If you guys could help I appreciate. Thank you.
