When using a commercial gateway to test WirelessHART Device's Application Layer, the messages burst by the DUT must be able to pass through the Gateway. Command 533 is the standardized command to enable publishing the burst messages through HART-IP devices (I/O Systems and Field Devices). Unfortunately, many WirelessHART Gateways do not yet support Common Practice Command 533 (which was added to the HART Protocol in 2016).  


So, even though the WirelessHART field device may be publishing burst messages, the packets do not reach the test application (the Gateway does not facilitate their passage).


Please make sure that you have the latest firmware update from your GW vendor. If they do not implement Cmd 533 yet, potentially false failures will be seen in the following tests -


CALU103B-C
CALU104B
CALU107A
CALU108B
CALU109A-C

At this time, we will accept submissions with these failures and confirm compliant operation of these tests in the FieldComm Group test labs.
