System integration:
Communication (configuration, parameterization) can be
performed with the DTM (Device Type Manager) available for
the device and the corresponding framework applications as
per FDT 0.98 or 1.2 (DSV401 R2).
Other tool/system integrations (e.g., Emerson AMS/Siemens
PCS7) are available on request.
The necessary DTMs can also be downloaded from
www.abb.com/flow.
