PRODUCT SAFETY ADVISORY
Notice of Potential Unsafe Condition
Rockwell Automation issues a Product Safety Advisory when it identifies a product(s) anomaly that may potentially cause harm to personnel, capital equipment loss or environmental damage. Immediate action is required as identified below.
Potential I/O Anomaly with 1732ES ArmorBlock Guard I/O Modules
Reference: 2017-10-003
Date: October 2017
This is a Preliminary Release of Product Safety Advisory 2017-10-003. Rockwell Automation is currently investigating the described anomaly and will provide additional details at a later date. The Knowledgebase Article ID 1066074 will be updated when this additional information is available.
This Product Safety Advisory informs you of a potential anomaly that exists with the 1732ES ArmorBlock® Guard I/O™ Modules. On some modules, connections internal to the product may short together. Depending on the application, this may result in the product not performing its intended safety function.

– Product Identification –
The potentially affected products are Bulletin 1732ES ArmorBlock Guard I/O modules, catalog numbers
1732ES-IB12XOB4, 1732ES-IB12XOBV2, 1732ES-IB12XOBV2-F, 1732ES-IB16, 1732ES-IB8XOB8, 1732ES-IB8XOBV4, and 1732ES-IB8X0BV4-F. Potentially affected modules will have a manufacturing date prior to October 1, 2017 (date code 2017/10/01).
New and unused product in the original factory packaging will show the product identification information on the carton label. The catalog number is in the CAT field and the manufacturing date is in the DATE field in the format of YYYY/MM/DD, where YYYY is the year, MM is the date code, and DD is the day of the month.
In the example shown to the left, the catalog number is 1732ES-IB12X0BV2 and the manufacturing date is 2016/05/24, or May 24, 2016. This product matches the catalog number and manufacturing date range and would be subject to this notification.
Installed product will show the product identification information on the product nameplate. The catalog number is in the CAT field and the manufacturing date is in the DATE field in the format of YYYY/MM/DD, where YYYY is the year, MM is the date code, and DD is the day of the month.
In the example shown to the left, the catalog number is 1732ES-IB12X0BV2 and the manufacturing date is 2016/05/24, or May 24, 2016. This product matches the catalog number and manufacturing date range and would be subject to this notification.
– Description –
A potential anomaly exists with the 1732ES ArmorBlock® Guard I/O™ Modules. On some modules, connections internal to the product may short together. Depending on the application, this may result in the product not performing its intended safety function.
Internal to the module, a product anomaly may result in various shorts between module signals. Specific to the safety function of the product, inputs and outputs can short to other signals. The effect of the anomaly depends on the module’s configuration and may affect the system’s safety performance level.
PRODUCT SAFETY ADVISORY

Important – Most shorts within the module will be detected when pulse testing is enabled on inputs and outputs. However, some specific shorts may go undetected as described below even with pulse testing enabled. The following table lists test output / input pairings that may result in undetected faults. The effect on your safety function depends on the channel configuration.

 In a single channel configuration, the listed test output / input pairings may result in undetected faults. If your configuration does not use one of these pairings the safety function of your module is maintained.
 In a dual channel configuration, if an individual dual channel pairing uses only one of the listed test output / input pairings, the anomaly will be detected and the safety function of your system will be maintained. If an individual dual channel pairing uses two of the listed combinations the anomaly may go undetected affecting the safety function of your system.
– Temporary Workarounds –
Important – Only individuals qualified, authorized, and responsible to secure safety in the design, installation, operation, and maintenance or the machine should perform the actions listed in this document. Consult Rockwell Automation Technical Support or your Rockwell Automation representative if you have any questions or concerns. Additional information on safety performance levels and categories may be found in ISO standard ISO-13849.
Important – Be sure to review the Description section of this document to determine whether this anomaly could adversely impact the safety performance level of your machinery, as determined by the required safety performance level for each of your safety functions. Customers who determine their safety systems are not adversely impacted by the anomaly associated with these modules may continue to operate their machinery. Customers must also review the conditions listed in the Description section of this document when system changes are made that affect the configuration of this product to ensure the product continues to perform its intended safety function.
Correction of this anomaly requires replacement of the affected module. Until a replacement module can be obtained and installed, customers whose safety performance level may be impacted by this anomaly are advised to discontinue use of this product or implement the following temporary workarounds.
 Enable pulse testing on all safety outputs and safety inputs.
PRODUCT SAFETY ADVISORY

 In a single channel configuration, re-configure your system to eliminate the use of test output / input combinations listed in the table above.
 In a dual channel configuration, re-configure your system to eliminate any individual dual channel pairings where both channels use test output / input combinations listed in the table above.
 Implement additional external safety systems to provide the required level of safety.
 Perform periodic manual tests of each impacted safety function.
If you’re unable to implement these workarounds, you may replace the 1732ES type module with a corresponding 1791ES, 1732DS or 1734 module. Implementation of one of these modules may require hardware and/or programming configuration changes.
– Correction –
Correction requires replacement of potentially affected modules. To request replacement product, contact your local Rockwell Automation Distributor or Sales Office, or other place of purchase, and reference this Product Safety Advisory PSA 2017-10-003. As of the release of this notification Rockwell Automation is replenishing inventory and expects to have product available by the end of November 2017 with limited availability until further notice. The Knowledgebase Article ID 1066074 for this notification will be updated when replacement product is released. Until replacement product is available customers are advised to take appropriate temporary actions as listed in the Temporary Workarounds section of this document.
