The HART Technology Working Group has improved the three Test Specifications (Token-Passing Data Link Layer, Universal Command and Common Practice Command) and created the new, TP-DLL Master Test Specification. The improvements are marked in blue with change bars on each specification. Please click on the red button below to view and comment on the specifications. Highlights of the improvements include: Token-Passing Data-Link Layer: 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. Universal Command: 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. Common Practice Command: 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.
See the Preface and Revision History in the individual documents for more information. The objective of the new TP-DLL Master Test Specification is to assure that a master properly arbitrates its access to the HART Token-Passing Data-Link Layer network. This is done (indirectly) by requiring the DUT to communicate with a network device (FD7) while the response TP-DLL tests are performed on a different device (FD0). This test specification is applicable to a variety of devices like HART 4-20mA I/O, WirelessHART adapters and Bluetooth HART modems. |
