Is it possible to read the code which has been saved in RCM4000?

Is it possible to read the already saved code in RCM4000 which has been set up for stand alone operation ?
If so can it be read in Dynamic C?

By the time the code is downloaded to the RCM4000 as a .bin file it is in machine code. It is unreadable by a human. You will need the source code that was used to create the .bin file.
