From the course: PLC Program Flow and Control Instructions
Return from subroutine (RET)
- [Instructor] The return from subroutine is an output instruction that marks the end of the subroutine file. It causes the scan to return to the main program, at the instruction following the GSR instruction where it left the program. It is a block type. Nothing is written inside because it simply just returned the scan back to where the subroutine came from. So the three instructions work together. JSR to jump to a subroutine, SBR to specify the number of the subroutine, and return is to return back to the main program.
