The following list contains information about the structure of these input boxes and the format
in which you can enter information in these boxes:
Parameter Meaning Example Default
Polling address HART address of the WirelessHART adapter.
● Default setting 15
● Range 0 ... -63 63 15
Master mode In a current loop, a device configurator such as
SIMATIC PDM and the WirelessHART adapter
(as examples) must be assigned different HART
master types.
● The default setting is primary master
● There is a primary master and a secondary
master.
● If you connect a device configurator or a an‐
other master/host, this must be set to secon‐
dary master.
Primary master
