System integration:
Communication (configuration, parameterization) can be
performed with the DTM (Device Type Manager, software
version B.10 and higher) 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.
