A backplane communication error may occur and trigger a complex sequence of events which can result in a 1756-L6X or 1756-L55 controller experiencing a major nonrecoverable fault, or cause other communications modules to assert. This anomaly can be triggered by using a 1756-ENBT module with unconnected message traffic in a system that does not include one or more of the following modules in the same chassis with the 1756-ENBT module: • 1756-EN2F • 1756-EN2T • 1756-EN2TR • 1756-EN3TR • 1756- EN2TXT • 1756-CN2/B • 1756-CN2R/B • 1756-CN2RXT • 1756-DNB/C • 1756-DNB/D • 1756-L7X • 1756-RM

As new firmware revisions of the 1756-ENBT module are released, previous versions of RSLogix 5000 software may not have those
newer 1756-ENBT module firmware revisions available in the Logix 5000 device selection list. To use a newer firmware revision of the
1756-ENBT module with an older version of the RSLogix 5000 software, add an older 1756-ENBT firmware revision to the project
and select compatible keying as the keying option. For example, if using version 16.00.00 of RSLogix 5000 software, selecting a 4.005
firmware revision with compatible keying will allow a revision 6.006 1756-ENBT module to function.
