Description
Use this parameter to define the HART protocol via which the device is to communicate.
•
HART 5 – HART® Protocol 5.9
•
HART 7 – HART® Protocol 7.2 (factory setting)
Note
•
If the HART® 7 function 'Write protection (Lock ALL)' has been activated via the DTM / EDD and
communication has been switched to HART® 5 on the device, write protection is canceled when the
device is restarted.
•
In the event of a switch from HART® 7 to HART® 5, if write protection has been activated via HART 7,
it is deactivated when the device is restarted.
•
When switching from HART® 5 to HART® 7, device addresses greater than number 15 are set to 0.
If 'Find Once' is selected, after HART command #73 is received the device responds once with HART
command #73, which has the same content as command #0.
If 'Find Continuous' is selected - after HART Command #73 is received, the device responds recurrently
with HART Command #73, which has the same content as Command #0.
Selecting the 'Off' parameter ends the 'Find Device' function.
