Connection with RFID reader via modbus tcp

Hi everyone, it's my first post on this forum. I am a beginner.

I'm trying to connect with INVEO RFID IND2 via modbus tcp. I created connections with no errors, I made the tags in mapping but all values has value zero. Nothing else. only zero. I can't wride to values on modbus device.

I can use only port 44818 - others are blocked. I can set port 44818 on the device and in configuration in Ignition.

Where I can looking for a mistake?

Port 44818 is used by EtherNet/IP. It is not generally used by Modbus. Are you sure this is a Modbus device?

Can you link to the device's user manual or other documentation?

Manual here:

Try using explicit node addresses in your tags. Like [D-28]1.HR2.

with this way of description address it works the same. I can see only zeros, but I’m sure the value must be other.

I must use port 44818 because others are block by other department of my company. In their opinion port 502 is dangerous.
