Rockwell Automation Allen-Bradley 1715-AENTR - HART Pass-Through

Rockwell Automation Publication 1715-UM001J-EN-P - December 2020 145
Chapter 5 Using 1715 Analog I/O Module Features
HART Pass-Through 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:
FieldStatus SINT Status
Field Device status:
Bit 7: field device malfunction.
Bit 6: configuration changed.
Bit 5: cold start.
Bit 4: more status available.
Bit 3: analog output current fixed
Bit 2: analog output saturated
Bit 1: non-primary variable out of limits
Bit 0: primary variable out of limits
ExternalDeviceStatus SINT Status
Extended field device status:
Bit 7: undefined.
Bit 6: undefined.
Bit 5: undefined.
Bit 4: undefined.
Bit 3: undefined.
Bit 2: critical power failure.
Bit 1: device variable alert.
Bit 0: maintenance required.
DataAge SINT Time
Time, in seconds, that indicates the age of the HART data
as follows:
0..127 : Age in seconds of the current data values.
-1 : Values un-initialized (i.e. no successful read at all, this
will be the power up condition )
-2 : Values are > 127 seconds old
