This Product Notice provides awareness of Global Positioning System (GPS) events that may affect time keeping capabilities of the 1756HP-TIME and 1756-TIME ControlLogix® GPS Time Synchronization modules. The GPS uses fixed size counters to manage various aspects of time keeping. When a counter rolls over (maximum value to zero) time keeping devices dependent on that counter may need to be updated to compensate.
