7.16 Operation with Emerson DeltaV
7.16.1 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. Install the Analyzer onto DeltaV
TM
NOTE:
The following procedures assume that the DeltaV and the analyzer are installed and powered.
