Input field interaction and bool dew is not taking any values

I want to give possibility of entering a real value from the display to operator. For that i am using Input field and configured all the parameters correctly in 800xA Rev 6.1.0.1. But I am not able to enter any value in it after saving. Same thing is happening with bool dew. I have checked doing same configuration in 800xA 6.0 version. there it is working fine. Any special configuration need to be done in 6.1.0.1 version to accept values from display?
