    • The inventor has recognized that industrial controllers may be updated after they are deployed in the field, while actively controlling an industrial process and without costly downtime, by storing a replacement machine-readable component in an allocated program space, locating and modifying one or more dependent machine-readable components copied in the allocated program space to instead depend on the replacement machine-readable component, re-linking a copy of the control program in the allocated program space, and redirecting execution to the control program in the allocated program space. Replacement machine-readable components could be instructions, libraries, or subroutines of the control program, and are not limited to user logic. The control program in the allocated program space may optimally be tested by verifying an operation before redirecting execution to the control program in the allocated program space.
