Now it's working. It was a user error as usual.
Display->Variable->Single : $SEN_PREA type of monitoring is kind of difficult to do. Once I did SPS to PLC and HMI monitor mapping I noticed that it is working after all.
I made the change to all Tx template files so i can get the force feedback in all the applications.
For some reason I'm missing all the decimal numbers of the force value. I tried to multiply the force values by 1000 in RSIVisualShell to move the decimal dot, but wasn't able to do that.
