HART Test Specification Change Log

• DLL033 was deleted making this a major revision.  
• General improvements were made to DDL010, DLL011, DLL024C, and DLL041.  
• The new Test Case, DLL022B, was added.  
• All burst mode tests were enhanced to abort if the DUT is HART-IP or WirelessHART.

• All test cases were enhanced to isolate Data-Link Layer requirements. 
• Minor improvements to UAL013, UAL011, UAL014, UAL038, and UAL48 were made. 
• A new test case was added to UAL013 for HART-IP. 

• FCG_TT20004{8.0} Common Practice Command Test Specification

• Many test cases were improved and / or simplified.  
• Modifications were made to simplify Voltage-Mode device testing.  
• New tests cases, CAL548 and CAL 552, were added for Digital Write Protect and DiffServ.  

• Revised a recommendation for DC power supply to have impedance under 1% of test load across a wide frequency range.
• Modified Oscilloscope requirements in section 10.2 to include filtering with a bandwidth of up to 20MHz and deep memory capacity.
• Clarified that a Frequency counter (section 10.3) is only required if the frequency of the signal generator needs to be verified.
• Updated Test Setups in sections 12 and 13 to ensure that standard set-up applies signals across the test load.
• Amended Waveshape Test in section 13.1 to include requirements and test procedures for amplitude variation, use of a specific test pattern, and generation of test patterns if standard responses do not yield the desired result. Also, updated the use of an oscilloscope for frequency measurement and provided updated sample waveforms.
• Revised Carrier Transients in section 13.3 to clarify start/stop transients.
• Updated figure in section 13.4.6 by removing reference to the inability to use a filter.
• Adjusted limits for receive impedance in section 13.6.

No changes for this release.

No changes for this release.

• Retired select test points which are superseded by the implementation of the Standard DDs in the latest FDI IDE and the Import/Redefinition Macros. 
• Additional test points were added to address the macros in the Standard DD. 
• Reorganized sections and test points that were previously in incorrect sections and made editorial adjustments for clarity and accuracy.

Specification) and those specific to the Token-Passing Data-Link Layer (which remain in DLL032).

• DLL034 (UAL004) and DLL038 (UAL015) were moved to Slave Universal Command Test

Specification.

• The "References" Subsections have been updated and typos in them fixed;

• Confirmation (in DLL018) that the Device Variable list is populated;

• DLL023 now confirms the Burst-mode Bit is set per Specification requirements;

• In FindNextDeviceVariable, use of Response Code "Dynamic Variables Returned for Device

Variables" is confirmed

• Added a couple of failure point numbers resulting from above improvements.

• Document number corrected from FCG TT20005 to FCG TT20003

• Corrected UAL009. msg1 no longer getting overwritten near FP 2785

• Improved UAL048 to reduce probability of false failures due to entering the test with More Status

Available set of Condensed Status interactions.

• Test cases were re-factored between the Token-Passing Data-Link Layer and Universal Command

Test Specifications. Application Layer specific requirements from DLL032 and DLL034 were moved to this Test Specification resulting in new test cases including:

• UAL003 Write Polling Address (Commands 6 and 7)
• UAL004 Read Unique Identifier with Tag (Command 11)
• UAL014 Read Unique Identifier (Command 0)
• UAL015 Read Unique Identifier With Long Tag (Command 21)

• Improved UAL011 to assess only Device Variables are used in Command 3.

• Removed UAL010 Verify Cold Start Bit. Cold Start Bit not useable on WirelessHART, HART-IP and questionable on HART 4-20mA.

• Corrected some entries in Table 5.

• Replaced Response Code 0 with "Success"

• Made some improvements to CAL104A

• Made a correction in CAL108A

• Fixed a typo in CheckBurstCommands - Table 26

• Made an improvement in CheckForCommand

• CheckReadyForBurst enhanced to initialize all burst message to a known configuration

• DisableBurstMode and EnableBurstMode modified to Disable/Enable all Burst Messages.

• Changed FP 109 to an Abort (not a Fail).Rearranged Test Sequence (§ 5.1) so that tests requiring UI are performed last.
