This Product Notice informs you of a potential anomaly that exists with the Allen-Bradley® 1715-AENTR Ethernet/IP Adaptor Module, the AADvance® T9110 Processor Module, and the AADvance T9120 Processor Eurocard. When used with redundant power supplies, the affected module may not detect and report the loss of a single supply. If the redundant supply is subsequently lost, the system will lose all power and shut down without system notification
Product Notice 2019-07-001: An anomaly exists with firmware versions 29.011 and 32.011 used with CompactLogix and Compact GuardLogix controllers. Customers may experience a major non-recoverable fault. Correction requires firmware update. Hardware is not affected and may not be returned on this notification. |
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.
