CANopen SDO and PDO

Hi All
 
I am new to CANopen protocol.
In my application , i have to communicate with a device using CANopen protocol.
The device is a sensor.So it will only transmit the data. I have to read that data.I am not able to start the communication (reading).I have supply 10 VDC to the sensor externally.
 
Now i am not able to understand SDO and PDO,NMT etc.
Whether i have to use PDO read function or SDO read function.
 
Please explain and if somebody is having any link then please send it
If possible , please send the example also
 
Thanks
Jass
