Multiplexing

System feature First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

Added support for channel multiplexing to allow use of all four input channels even in high bandwidth applications, where only one or two channels can be enabled at any one time.

Redundant Tacho Mode

System feature First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

The ability to have the DSP switch tacho sources (between T0 and T1 configured sources) if a tacho returns a Not OK.

Module Security

System feature First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

Changes have been made to module security:

• Module owner credentials (vendor ID and SN) are no longer stored to NV memory such to allow a module power cycle to unlock a module (not normally terminated class 1 I/O connection)
• Compliance mode is no longer used as criteria for allowing a module reset. This feature makesit easier to use software reset to bring module in required out-of-box state for firmware update (API and SIL modes).
• Fixed anomaly to make sure that no reset is allowed when an I/O connection is active or when module is owned.

Wire-Off

System feature First Identified as of Firmware Revision 2.002

IP Addressing

System feature First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

Module will now allow direct BOOTP/DHCP mode when address switches are set to any non-fixed IP address (‘000’). Previously a software Type 1 reset or hardware out-of-box (‘888’) reset was required.

X/Y + HPF Application Type

System feature First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

Added support for X/Y-based Eddy Current Probe measurement with the use of HP filter for overall measurement assessment.

Dynamic Pressure + Filter/Overall Application Type

System feature First Identified as of Firmware Revision 2.002

Bulletin 1444 Buffered Outputs

Corrected Anomaly with Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

This is a hardware change. The change is effective beginning with modules manufactured after 13 July 2017. 

Catalog Number 1444-DYN04-01RA

• Buffered outputs susceptible for injected common-mode noise

• BNC output operational limitations

Buffered output circuit are modified to eliminate injected common-mode noise, and to make the BNC and terminal pin outputs equivalent with respect to performance.

Revised Buffered Output Specifications

1444 Reset Behavior Changes

Corrected Anomaly as of Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Number 1444-DYN04-01RA

Previous behavior would only reset the Auxiliary processor and therefore did not mimic the power startup behavior.

New behavior is that both the Aux Processor and the DSP are restarted.

Type 1, 2 Out of Box Reset

Main functionality is to return the module to Out‐of‐Box defaults.

Previous behavior would reset Auxiliary processor and DSP and upon boot load default configuration to DSP.

New behavior will not reset DSP, but will activate default configuration, reset Auxiliary processor that will then reconfigure DSP with default configuration and restart data acquisition.

4-20 mA Output in Transducer Fault Condition

Corrected Anomaly as of Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Numbers: 1444-DYN04-01RA

Corrected error where 4‐20 mA output channels 1, 2, and 3 (channel 0 OK) would not output defined high or low (typically low) current output to indicate Transducer Fail condition.

Aux Bus Communications when configured for 20 kHz measurements

Corrected Anomaly as of Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Number 1444-DYN04-01RA

An anomaly has been corrected where a module configured for ≥20 kHz could force an ExpBusOrExpModuleFault indication.

For heavily loaded configurations (for example, 20 kHz), the allotted loop processing time may be too short to process all tasks. For these conditions, the typical loop time of 47 ms can be extended to ensure all tasks will be completed.

A problem has been detected in how this algorithm was applied to 20/40 kHz applications and additional algorithm optimization has been applied to keep heavy loaded 20 kHz configurations within 100 ms process time.

Note that the ModuleLoadWarning and ProtectionPerformanceWarning status tags will be set as appropriate when the loop time exceeds 47 or 100 milliseconds, respectively.

Synchronous Sampling-based Transient

Corrected Anomaly as of Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Number 1444-DYN04-01RA

Corrected behavior where transient trigger would occur in sample buffer data time period, which can be long based upon synchronous sampling at low startup speed, such that pre‐trigger data would be included in transient data. Occasionally this effect could also capture data exceeding the high level RPM threshold.

Sample data block processing has now been replaced with RPM trigger and sample time trigger filter to prevent data storage outside low and high threshold levels.

Run‐up Transient at Module Startup

Corrected Anomaly as of Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Number 1444-DYN04-01RA

Corrected issue where a run up transient would be logged (incomplete, single measurement value) in case module would startup with an active speed signal higher than run‐up low RPM threshold.

DSP Reconfiguration – Trip Inhibit Extension

Corrected Anomaly with Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Numbers: 1444-DYN04-01RA

During process that Aux Processor sends configuration to DSP, the Aux Processor will issue a trip Inhibit during reconfiguration and also speeds up the DSP to optimize reconfiguration time. When DSP report first ready state, used to disable DSP speed-up process, the trip inhibit was also disabled, but as further settling may be required as result of enabling normal configuration, the next DSP ready state is now used to disable the Trip Inhibit and as such eliminates potential alarming as result of final settling.

Disabled Measurement Alarm no longer allowed in Voted Alarm Logic

Corrected Anomaly with Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Numbers: 1444-DYN04-01RA

The AOP will no longer allow a configuration that includes voted alarms that reference disabled measurement alarms. However, in addition, the Aux Processor firmware has implemented a second level configuration validation scheme where for each voted alarm the used measurement alarm input is validated to be enabled. In case of detected issues, the configuration will be rejected as FW cannot force enable of alarms nor disable of active voted alarms or ignore disabled measurement alarm inputs. It is simply handled as a bad configuration.

Expansion Module Hot Swap

Corrected Anomaly with Firmware Revision 4.006

Known Anomaly First Identified as of Firmware Revision 3.002

Catalog Numbers: 1444-DYN04-01RA

Note that with the ExpansionModuleSummary status set, a configuration write will be forced even if the ‘existing’ configuration is just being refreshed (no difference is required).

Bulletin 1444 Electronic Keying

Known Anomaly First Identified as of Revision 2.002

Catalog Number 1444-DYN04-01RA

For the Add On Profile Version 79, the Alternate Path signal source selection is selectable even when Alternate Path signal processing is OFF.

ADC-out Source Selection

Known Anomaly First Identified as of Revision 2.002

Catalog Number 1444-DYN04-01RA

For the Add On Profile Version 79, the ADC-out signal source selection should not be selectable when using a 40 kHz Module Personality.

Module Definition Default Unicast Setting

Known Anomaly First Identified as of Revision 2.002

Catalog Number 1444-DYN04-01RA

When Module Definition changes are made the AOP will reset the Unicast selection to default.

Time Sync

Known Anomaly First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

In some cases, the module can report that it is synced when it has large discrepancies in System Time.

Redundant Controllers Support

Known Anomaly First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

Support for redundant controllers is not provided.

gSE FFT Improperly Scaled

Known Anomaly First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

gSE FFT data, as read by software, is off (high) by a factor of 2.828.

Module Firmware May Default to Recovery Mode

Known Anomaly First Identified as of Firmware Revision 2.002

Catalog Number 1444-DYN04-01RA

During pulsed power cycles, it is possible for the module to fault to Recovery mode, which requires you to update the firmware. This can occur if power is lost while the firmware is updating nonvolatile memory.

4…20 mA Output Measurement Wrapping

Known Anomaly First Identified as of Revision 2.002

Catalog Number 1444-DYN04-01RA

If the measurement value is much larger than the configured scale, the 4…20 mA value may wrap around as normal measurement result.

Use Local Bus Extension Cables

Application Notes

Catalog Number 1444-DYN04-01RA

The system is designed to be installed in a specific manner. Expansion modules fit to the right-hand side. The base-mounted headers are latched and, for additional security, cannot be removed (or inserted) while there is a module in place on that base.

Voted Alarm Status Values

Application Notes

Catalog Number 1444-DYN04-01RA

IMPORTANT: Voted Alarm Status records do not associate 1:1 to the 13 Voted Alarm definitions. Reference the Alarm Number attribute (bits 10-13) of each Voted Alarm Status record to identify the Voted Alarm that the entry applies to.

Voted Alarm Status Record Assignment

Voted Alarm Status records are applied first to physical relay. This assures that every physical relay has an associated Voted Alarm Status record even if the relay is not used. For example, if an application includes one 1444-REX00-04RB Expansion Relay module (address 1) and the configuration enabled relays 0 and 2 from the expansion module referencing them to Voted Alarms 0 and 1, plus enabled the main module’ s onboard relay with it referencing Voted Alarm 12, then the Voted Alarm Status records would be allocated as shown here:

Once Voted Alarm Status records are allocated to any physical relays, any remaining Voted Alarm Status records will be assigned to any Voted Alarms that were not already assigned, having been associated with a physical relay. This allocation is done simply by assigning unreferenced enabled Voted Alarms, in order, to the next available Voted Alarm Status record. For example, if the above configuration also enabled voted alarms 7-11 to use as ‘ virtual’ alarms, then the Voted Alarm Status record allocation would be:

Note that it is possible for an enabled Voted Alarm that is not referenced by a physical relay to not be referenced by a Voted Alarm Status record.
