I have no access to this address ... 

The Modbus holding register (50514) is a double register (50514 + 50515). You have to transfer 2 words at the start address 50514.

But there is a problem. This value is a 32 Bit unsigned integer value. The LOGO! can only read 32 bit or 64 bit float values with the F/I converter, but not 32 bit or 64 bitunsigned integer values.

Example:

You transfer 2 words from the start address HR50514 to the LOGO!, start adress VW0, 2 words.

If the value is smaller then 32,768 then can you read the value in the right 2 bytes, in this case VW2 with a normal analog network input.

But are you sure that the Modbus port is 505? And the Unit-ID is 255?

Maybe, you have to enter 50515 (+ 50516) as the start address because it works with an offset of +1.

By default, the Modbus server has port 502. I'm surprised why you entered port 505 in the data transfer table.

I don't know what unit ID your Modbus device has, nor does it appear from the documentation.

What is the voltage you are measuring?

Is it a 230VAC? If so, you can get by with the simple analogue network input. For example, at 230 VAC it would be 230.00. The analog network input could read up to a maximum of 327.67 VAC.
