  • Patent number: 8117434
    Abstract: Aspects of the invention support a component configuration mechanism when rebooting a circuit module (201) of a programmable logic controller (101). A component (application) may be configured from a plurality of sources, including flash memory (204) and a web-based configuration source. The configuration mechanism avoids using invalid configuration data when replacing the communication module. The circuit module may support a plurality of components, where some of the components may be associated with a web-based configuration while other components may be associated with a CPU-based configuration. If the configuration data in the flash memory of the communication module is determined to be invalid, the communication module obtains configuration data from a web-based configuration source for a web-based configured component and from an associated CPU module (202) for a CPU-based configured component.
