The HART Pass-Through feature enables using an external asset management
system to manage HART compatible field devices connected to a 1715
controller.
HART Pass-Through uses the device type manager (DTM) standard, defined by
the HART Communication Foundation, to enable using any asset
management system which using the generic 'Frame' standard. Examples of
compatible tools are the Fieldcare application by Endress+Hauser and the
FactoryTalk® AssetCentre software by Rockwell Automation.

Using HART Pass-Through

The Controller tags created when an analog input module (1715-IF16), or analog
output module (1715-OF8I), are added to an application, contain variables to
monitor HART data.
To use HART Pass-Through, you have to install the 1715-DTM software on the
computer which is running the asset management system. You can then
enable and disable the HART Pass-Through capability of the 1715 Adapter.
For an analog module, HART data is available to the application in the ChHart
array element of the modules input tag when the module has HART enabled,
for example:

Time, in seconds, that indicates the age of the HART data
as follows:
0..127 : Age in seconds of the current data values.
SINT Time
-1 : Values un-initialized (i.e. no successful read at all, this
will be the power up condition )
-2 : Values are > 127 seconds old
