About AMS and DeltaV
Software
AMS and DeltaV software allows users to manage their instrumentation, and
to perform on-line configurations of their instruments.
The ability to communicate with instruments and configure instruments on-line
facilitates instrument commissioning and loop validation.
With AMS, users can also access status and diagnostic data from smart
devices and monitor their performance.
AMS leverages the I/O capabilities of the control system to gather asset
management data without interfering with the control system’s operations.
