Patent ID: 8001419

Claim:
An industrial automation controller module comprising: a main module comprising processor circuitry, volatile memory, and non-volatile memory, wherein said processor circuitry, volatile memory, and non-volatile memory are electrically powered by operating power; an energy storage module removably connected to the main module and adapted for selective manual separation from the main module, said energy storage module comprising a back-up power source; wherein said back-up power source of said energy storage module selectively supplies back-up power to said processor circuitry, volatile memory and non-volatile memory of said main module for an emergency save operation in which data from at least one of said processor circuitry and said volatile memory are saved to said non-volatile memory in response to interruption of said operating power; wherein said energy storage module includes one or more configuration parameters related to said back-up power source that enables the main module to validate the energy storage module for requirements of the main module.
