Expert Answer
a) The forcing capability of PLC allow the user to external input output turn on or off regardless of the users device.
b)
Practical uses of the forcing function is selfevidently useful in safety critical work process.
For example consider a user wants to delete five files if it done by human the user may continues to delete the file even when he deleted the five files and so inorder to show him that it is sixth file there needs an extra feature thus here the forcing function can be used.
