Posted by plcsoft on 13 November, 2007 - 12:03 am
I am using Twido 40 DRF to communicate with Magelis XBTN400 HMI to monitor some temperatures which are in % Mw0 % Mw1 ...and so on.

I am using Modbus and the communication setting at Twido is
Baud rate: 9600
Parity: Even
Stop bit: 1

The settings are same at Magelis.

I am geting ???? at the fields where I should see the temperature.

What could be causing this?

Thanks.
