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.

In the example collection tool data file output shown above, the serial number of AADvance T9110 module in the A slot is 84-1407-9110-5-00091. The date code for this module is 1407, or July 2014. This module would be subject to this notification.

DESCRIPTION

A potential anomaly 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 control system will lose all power and shut down without system notification.

Internal to the potentially affected modules are blocking diodes that prevent power from one power supply affecting the detection circuitry for the other power supply. When a single supply becomes non-operational, the detection circuitry signals the system of the loss resulting in an LED indication on the module’s faceplate and the generation of a fault alarm. The system will continue to operate on the remaining supply.

On a small percentage of modules, the blocking diodes may allow power from the remaining operational power supply to affect the detection circuitry for the non-operational power supply. This will prevent detection circuitry for the non-operational supply from signaling a loss supply condition to the system.

TEMPORARY WORKAROUND

No temporary workaround has been identified. Customers are advised to check for this condition and, if determined the module or card is affected, take appropriate corrective actions as described in the Correction section of this document.

CORRECTION

ATTENTION: Only persons skilled in the maintenance of industrial control and electrical equipment should attempt to perform the following test and remediation actions. Failure to follow industry standard safety procedures, including Lock-Out / Tag-Out (LOTO) and use of appropriate levels of personal protective equipment (PPE), may result in harm to personnel or loss of equipment. Make sure you read and understand all warnings as provided in the product installation and service documentation.

Important – Prior to requesting module repair or replacement, customers must perform a power loss test to determine if the module or card is affected by this anomaly. Test procedures specific to module type are included in Appendix B of this notification. [Refer to the attached PDF documents].  If testing determines your module is not affected, no action is required.

Customers requesting repair should submit a request for a Return Material Authorization (RMA) by sending an email to returns@ra.rockwell.com with subject line “PN 2019-07-002 RMA Request”. An RMA will be returned by email with processing instructions.

Customers requesting replacement or exchange product should contact their Rockwell Automation System Integrator, Distributor, or Sales Office, or other place of purchase. Make sure to reference this Product Notice PN 2019-07-002 when requesting replacement product.
