Hi, Nilesh
First check wheather u have configured proper module in hardware configuration in Simatic Manager. Check what u have confgured that channel as i.e 0-10 v or 4-20 mA or RTD type ...the check the connections made to the terminals of the modules r correct or not and try to read the counts in VAT table. Also get the transducer catalog or manual for reference.

Hope this will show you the way ..
