Chapter 7 Configure the Modules with RSLogix 5000 Software
HART Configuration
The Input Data formats on the General tab let you access HART field device data
through automatic collection of the HART Field Device Process Variables and
Health information.
You can also access HART field device data with pass-through messages. See
Getting HART Data By Using CIP MSG on page 121
and HART Modules
Used with Asset Management Software on page 141 for more information.
Table 20
shows which configuration options provide HART data in the input tag
and which provide pass-through message access.
Even if you are not enabling HART on all channels, the Analog and HART PV
input tag includes space for the data, but it will be marked with a HARTFault to
indicate it is not valid. This lets you add HART instruments later without
disturbing the tag layout.
