Abstract
An industrial automation controller module includes a main module and an energy storage module (ESM) releasably connected to the main module. The ESM includes a back-up electrical power source such as a battery or a capacitor that is electrically connected to processor circuitry of the main module when the ESM is physically connected to the main module. In case of interruption of operating power to the processor circuitry of the main module, the back-up power source of the ESM supplies back-up power to the main module to allow for completion of an emergency save operation to save data to non-volatile memory in the main module. If the ESM includes a capacitor back-up power source, it is charged by the main module and the capacitor charge is dissipated if the ESM is separated from the main module. In all cases, the ESM can include one or more configuration parameters stored therein that allow the main module to validate (or not) the ESM for the requirements of the main module, with respect to type of back-up power source, product code or model, capacity of back-up power source, and the like. The main module can also initiate periodic testing of the back-up power source of the ESM.
