Intermittent Fault of FLEXHA 5000 Backplane Interface Module

Known Anomaly First Identified as of Firmware Revision 1.011

Catalog Number 5015-BIMXT

A FLEXHA 5000™ can intermittently indicate the presence of a Base Interface Module (BIM) fault that is not the result of a failing BIM.

When this anomaly occurs, both the S:Basex.InterfaceAInternalFault and S:Basex.InterfaceBInternalFault adapter tags for the same base transition to 1. (x represents the base number.)

These faults may clear without user intervention and may reassert at a later time.

An event that results in only a single S:Basex.InterfaceAInternalFault or single S:Basex.InterfaceBInternalFault adapter tag transitioning to 1 is not the result of this anomaly, and should be diagnosed accordingly.

Known Anomaly First Identified as of Firmware Revision 1.011

Catalog Number 5015-U8IHFTXT

An anomaly exists in the following conditions:

• A FLEXHA 5000™ 8-channel Universal I/O module resides on an I/O base.
• A channel on the module is configured for analog output mode and is connected to a HART device.
• The backplane A and B connections from Adapter base to the I/O base break.

When the backplane connections are restored, the connection between the channel and the HART device isn’t restored. As a result, the channel faults and HART data is not available. The channel’s status indicator flashes red and its NoLoad input tag changes to 1.

To restore the connection and resume normal operation, complete one of the following:

• Change the channel’s ResetFault output tag to 1 and then change it back to 0 after the fault is cleared.
• Cycle power to the I/O either by removing and reinserting it or unlocking and relocking it.
