HART COMMUNICATION
The Logix 420 series positioners use the HART
communication
protocol specified by the HART
Communication Foundation.
11.1 ValveSight DTM
Flowserve Corporation has produced a custom Device
Type Manager (DTM) for the Logix 420 digital positioner to
support the ValveSight diagnostics platform.
The DTM contains a high level “Dashboard” view of the
system health and status information. It also contains
comprehensive user-friendly interfaces for control and
reporting of alarms, of-line and on-line diagnostic tests,
calibrations and system configurations.
The ValveSight DTM is available from a Flowserve
representative or from www.valvesight.com.

11.2 HART 475 Handheld Communicator
The Logix 420 digital positioner supports and is supported
by the HART 475 Handheld Communicator. The Device
Description (DD) files can be obtained from the HART
Communication Foundation or from your Flowserve
representative.
11.3 Burst Mode
Burst Mode is available with a handheld device. In the
menu of the handheld, select the Burst Mode feature under
the Configuration Menu.
NOTE: The DTM will not function while the positioner is in
Burst Mode.

The Logix 420 positioner comes standard with the HART 6
communication protocol. Follow this procedure to change
to HART 7.
