The AADvance provides a transparent connection between the asset management
software and the field device. AADvance controller provides a global control variable
allowing the user to control HART Passthru via the application, the AI and AO
channels each provide variables for monitoring HART Passthru activity:
 one to monitor the elapsed time since the last non-pass-through communication
(AIM_HART_FULL_xx.ELAPSED)
 and one to indicate that HART messages are in progress
(AIM_HART_FULL_xx.PASSTHROUGH).
To use the pass-through feature you must configure a communication path for the
AADvance DTM, provide the control to enable the communications through the
Processor and configure the HART structure to each I/O channel connected to a
HART Field Device.
