1756-OF8H HART Analog Output Module Shutdown Posted on March 1, 2019 by Brandy McNeil 1756-OF8H HART Analog Output Module Shutdown Product Safety Group 1201 South Second Street Milwaukee, WI USA 53204 productsafety@ra.rockwell.com PRODUCT NOTICE Notice of Potential Product Concern Rockwell Automation issues a Product Notice when it identifies a product(s) anomaly that may cause commercial or customer satisfaction concerns. 1756-OF8H HART Analog Output Module Shutdown Reference: 2019-03-001 Date: March 2019 This Product Notice informs you of a potential anomaly that exists with the ControlLogix® HART Analog Output Module, catalog numbers 1756-OF8H, 1756-OF8H-CC, and 1756-OF8HK. In rare instances, modules manufactured October 1, 2016, through February 28, 2017, may shut down without fault state notification. PRODUCT NOTICE Page 2 of 5 – Product Identification – The potentially affected product is the ControlLogix HART 8-channel Analog Output Module, catalog numbers 1756- OF8H, 1756-OF8H-CC, and 1756-OF8HK. Potentially affected products were manufactured October 1, 2016, (date code 2016/10/01) through February 28, 2017, (date code 2017/02/28). On installed product, the product identification information may be found on the module nameplate label. The Catalog number will be in the CAT field located above the CAT barcode. The manufactured date will be in the DATE field located toward the bottom center of the nameplate and will be of the format YYYY/MM/DD, where YYYY is the year, MM is the month code, and DD is the day of the month. In the example shown to below, the catalog number is 1756-OF8H and the date of manufacture is 2016/09/23, or September 23, 2016. The catalog number matches the product identification, but the manufacture date of this example is not within the potentially affected product date range. This label as shown is an example only and would not be subject to this notification. For unopened product still within the product carton, the product identification information may be found on the shipping carton label. The catalog number will be in the CAT field located on the left side of the label. The manufactured date will be in the DATA field located on the right side of the label and will be of the format YYYY/MM/DD, where YYYY is the year, MM is the month code, and DD is the day of the month. Customers with unopened product are asked to return product with the factory carton seal intact. In the example shown to the left, the catalog number is 1756-OF8H and the date of manufacture is 2016/09/23, or September 23, 2016. The catalog number matches the product identification, but the manufacture date of this example is not within the potentially affected product date range. This label as shown is an example only and would not be subject to this notification. PRODUCT NOTICE Page 3 of 5 – Description – A potential anomaly exists with the ControlLogix® HART Analog Output Module, catalog number 1756-OF8H, and the conformal-coated variations 1756-OF8H-CC and 1756-OF8HK. In rare instances, modules manufactured October 1, 2016, through February 28, 2017, may shut down without fault state notification. In a small percentage of modules manufactured within the listed date range, a component internal to the module may stop operating resulting in a loss of communication between processors within the module. The loss of communication causes the connection to the controller to time out. However, the module itself does not receive a fault state event and the module will continue to output last state instead of the configured fault state. – Temporary Workarounds – No workaround has been identified for this anomaly. – Correction – Correction requires replacing the module. 1756-OF8H modules that match the product identification information above may be returned for replacement or exchange. 1756-OF8H-CC and 1756-OF8HK conformal-coated variations may be returned for replacement only.
