After replacing the module, you must reinitialize the hardware configuration in your engineering software (TIA Portal, RSLogix 5000, etc.). The UPD presents a different device ID (0x342F vs. 0x299A for the original).
Component lifecycles in industrial automation typically last 10–15 years. The original FC22340960 debuted around 2013, with the UPD version released in 2018–2019. Given current trends, we can project:
software patch, firmware update, or system-specific configuration code
